Changelog

What's new

The latest features and improvements on Learners.Center — newest first. You're on v1.54.0.

v1.54.029 September 2026

Lessons in five short parts

Every lesson now comes in five short, titled parts, with more room to read.

  • Five short parts — Each lesson is split into five parts, each with its own title and a line above it, so you can see where you are and how much is left.
  • Jump to any part — On a laptop or desktop, the sidebar lists the five parts of the lesson you're on and marks the one you're reading. Click a part to go straight to it.
  • More room to read — More space between cards, shorter lines of text and roomier quizzes make every lesson easier on the eyes.
  • Clearer explanations — After you answer a question, the explanation sits apart from the options in a lighter style, so the reasoning is easier to follow.
v1.53.027 September 2026

Your school's own portal

Each school now has its own portal, open only to its staff and students.

  • Only your school — Your school's portal is just for your school. Sign in and join your class with the code your school gives you, and everything opens up.
  • Opens when your school is ready — Until your school's portal is open, its page tells you so. Your school will let you know when you can join.
  • Pro through your school — Plans and checkout aren't part of your school's portal. Your school's plan covers you, and Billing shows how.
v1.52.027 September 2026

Courses chosen for your school

Learners.Center now chooses the courses each school gets, including school subjects the main site doesn't show.

  • Your school's own courses — On your school's portal you see the courses Learners.Center chose for your school. They can include subjects you won't find on the main site.
  • Clearer for teachers — When your school's staff add a course to a class, they pick from your school's courses. If one is missing, they can ask for it under Course requests.
  • Find your class's courses anywhere — If your dashboard on the main site has a course from your school that isn't listed there, it links you to your school's portal to open it.
v1.51.026 September 2026

Faster lessons, and pictures you can play with

Pages now load a small part of what they used to, courses can be improved without waiting for a site update, and lessons are ready for a new kind of interactive picture.

  • Courses that keep getting better — We're rewriting lessons with clearer explanations, more examples and better questions. Each update now reaches you as soon as it's ready, without waiting for the site itself to change.
  • Faster pages — Every page used to download every course in the background. Now a lesson loads only the course it belongs to, so pages open faster, especially on a phone.
  • Pictures you can try — New lessons can include interactive pictures. Step through them, press their parts and watch the idea play out. They work with a keyboard and a screen reader too.
  • What each module teaches — Course pages can now show what you'll be able to do after each module, how long it takes, and answers to common questions about the course.
  • Clearer when a lesson won't load — If a lesson can't load, you now see what happened and a Try again button. Your progress stays safe.
v1.49.023 September 2026

Your school, on Learners.Center

Schools can now run their own portal on Learners.Center, at their own address.

  • Your school's own address — Each school's portal has its own address, like dps-noida.learners.center. It shows your school's name, and takes you straight to signing in or creating an account.
  • Join your class with a code — Enter the six-character code your school gave you, pick your class and section, and you're in. You can leave a school from the same page, and your own progress always stays yours.
  • Pro through your school — While your school's plan runs, you get Pro: every course, the AI tutor and certificates, with nothing to pay. Billing & plan shows your school and the date the plan ends.
  • From your school — Your dashboard now shows the courses your school chose for your class, in the order your teachers added them.
  • A console for your school's staff — School staff sign in to their school's portal and open the school console. It shows the join code to share, how many students have joined, and every class and section. Staff choose which courses each section sees, for one section or the whole class at once, and look after their students: roll numbers, moving a student to another section, and removing or restoring them.
  • Ask for a course we don't have yet — Every course in the catalog is your school's to use. If you need one that isn't there, ask from the school console and follow its answer on the same page.
v1.48.023 September 2026

Learn any skill, the simple way

Learners.Center has grown well past coding. The site now says so, and makes it easier to find where to start, whatever you want to learn.

  • Browse by subject — Courses are now grouped into four subjects: coding and tech, AI tools, marketing and search, and money and business. Pick one on the courses page, or follow a link from the home page.
  • Start from your goal — The home page asks what you want, like "I want more people to find my business", and takes you straight to the path or course that gets you there.
  • Paths on every course page — Each course now shows which career paths it belongs to, and a few related courses to try next.
  • Answers up front — Common questions about pricing, the AI tutor, certificates and learning on your phone are answered right on the home page.
v1.47.010 September 2026

Five new career paths

The twelve marketing and money courses now read as a track rather than a pile. Five new career paths, six new onboarding interests, and a catalog that finally describes what's actually in it.

  • Digital Marketer — Six courses, starting with the map — how the channels differ and which ones a business should actually use — then search, social and paid advertising properly.
  • Performance Marketer — The paid-media specialist track: the auction underneath every ad platform, then Google and Meta in depth, then how to prove what your spending actually caused.
  • Freelancer — Getting clients, pricing properly and keeping the money — the business of working independently, plus the marketing skills clients actually pay for.
  • Search Specialist — Everything that happens when someone searches: organic ranking, getting cited by AI answer engines, buying the results you can't earn, and reading your competitors.
  • Creator & Monetisation — Build an audience, then turn it into income — including the arithmetic nobody publishes about what a pageview is really worth.
  • Onboarding finally serves what it asks — "Digital Marketing" has been an option since launch with no courses behind it. It's now a real career path, alongside five new interests that each map to a track.
v1.46.010 September 2026

Ad Library Research is live — and the business track is complete

28 lessons on reading your competitors' ads without fooling yourself, using tools built for election accountability. Six research simulators on two working ad corpora. This completes the twelve-course business and marketing track.

  • Discover that a year-old ad is weaker evidence than a two-month-old one — Advertisers turn off what doesn't work, so survival is evidence. But a share of losers is never turned off, and those pile up in the long tail — so the signal peaks at about day 54 at 4.19× and declines to 2.68× by a year. Nobody tells you the second half of that.
  • Read a competitor's health from the shape of their library — One advertiser has ads at 214, 142 and 96 days — three things that work. Another has four ads under ten days old and a discount that went from 40% to 45% in two days. Neither fact required looking at a single image.
  • Find out who's bidding on your brand name — Conquesting is visible on Google's transparency centre and invisible on Meta, because search ads name their target. And the run length tells you whether it's working for them — 143 days means it is.
  • Build a pricing map nobody meant to publish — Search ads have no image doing the work, so they state prices, shipping thresholds and return windows in the copy. An afternoon gives you a competitor pricing map for a whole category.
  • Find a category gap and check whether it's real — An empty cell might be an opportunity or it might be empty for a reason. The test is whether anything adjacent survived — and interrogating that is what separates a gap analysis from a list of things you noticed.
  • Learn what these tools genuinely cannot tell you — No spend data. No performance data. No targeting. Any tool claiming otherwise for commercial advertisers is estimating from the same public data you can see free — and knowing that boundary is what makes the rest trustworthy.
v1.45.010 September 2026

Meta Ads is live

36 lessons on Facebook and Instagram advertising — interruption instead of intent, and the arithmetic that decides whether the platform can work for you at all. Nineteen simulators, every figure computed.

  • Find out if your budget can work at all — ₹3 lakh a month at a ₹650 cost per conversion supports exactly two ad sets above Meta's learning threshold. Most accounts run ten — which means every one of them is permanently unstable, and no amount of creative skill fixes an arithmetic shortfall.
  • Discover why three creative tests find nothing — About one concept in eight is a winner, so testing three gives you a 67% chance of finding none — and concluding, reasonably and wrongly, that Meta doesn't work for you. Eighteen concepts gets you to 90%.
  • Settle the broad-versus-detailed argument — Detailed targeting genuinely wins for the first 384 conversions. Broad wins after that, and reaches 1.82× by 4,000. Both camps are right; nobody states the condition.
  • See retargeting's beautiful, misleading numbers — Reported, retargeting looks 3.4× better than prospecting. Strip out the people who'd have bought anyway and it's identical. Shifting ₹2 lakh between them looks like +611 conversions and is worth about +2.
  • Learn what the pixel actually sees — Roughly 60% of your conversions, since the privacy changes. And because the learning phase counts what it can see, that raises the real conversions you need each week from 56 to 83 — a cost of poor tracking that never appears as a line item.
  • Find where profit turns, not where conversions do — Profit peaks at ₹16 lakh a month. Spend ₹64 lakh and you take 2,601 conversions — more than twice as many — and lose ₹6.8 lakh. Any team rewarded on volume scales straight past the peak.
v1.44.010 September 2026

Google AdSense is live

24 lessons on the other side of the auction — what it's actually like to sell the attention every other course teaches you to buy. Sixteen simulators, and the arithmetic nobody publishes.

  • Discover that more ads means less money — Revenue peaks at four ad units. Impressions keep climbing to nine. Ten units serves 2.5× the impressions of four and earns 60% as much — and a second, completely independent model about page speed points at the same number.
  • See why Indian readers click more and earn you less — Indian click-through rates run higher than American ones, and the revenue per thousand pageviews is 89% lower. That single fact settles what the lever is — and it isn't your layout.
  • Find out what your income goal actually costs — ₹50,000 a month needs 774,000 pageviews on a legal site and 25 million on a lifestyle blog. Same effort per article, thirty-three times the requirement.
  • Watch why your own clicks are always caught — Ten ad clicks from one device is a 1-in-84-trillion event. Not suspicious — statistically impossible. And that's the weakest evidence Google has.
  • Learn that the best ad slot isn't at the top — The first paragraph break is seen 82% of the time; the top of the page only 68%. The footer earns 11% of what the best slot earns, while still costing you load time.
  • Price your own time honestly — A display-only site on an ordinary subject pays about ₹18 an hour at 300,000 monthly pageviews. The same hours on a different subject with four monetisation layers pays ₹482. Neither number is about working harder.
v1.43.010 September 2026

Google Ads is live

36 lessons on the platform itself — structure, tracking, Smart Bidding and Performance Max — with the arithmetic behind every rule. Twenty simulators, and every figure in the text generated by the same formula the engine on screen evaluates.

  • Watch pinning destroy 93% of your ads — Fifteen headlines and four descriptions assemble 32,760 different ads. Pin one headline and it falls to 2,184. Pin two and you have 156. Almost every pin in almost every account fails the test for whether it was needed.
  • Find the target CPA that actually makes money — The standard advice — set your target at what a conversion is worth — spends ₹39,20,400 to earn exactly ₹0. The profit-maximising target is half of it: ₹9,80,100 spent, ₹9,80,100 kept. Drag the slider and watch the profit curve peak and then fall off a cliff.
  • See why campaigns get killed at 9am — A campaign genuinely returning 3.2× reads 0.30× the morning after, because only 9% of its conversions have landed. Three weeks later it reads 3.04×. Nothing about the campaign changed.
  • Settle the Google Ads versus GA4 argument for good — One thousand real conversions. Google Ads reports 1,000 and GA4 reports 570 — a CPA of ₹1,450 or ₹2,544 for the same customers. Four documented rules explain the whole gap, and neither tool is wrong.
  • Catch Performance Max flattering itself — A campaign reporting ₹1,140 against a ₹1,200 target, green on every dashboard. Strip out the brand searches that would have converted anyway and the real cost is ₹1,953 — with four of its six surfaces individually over target.
  • Learn how long you have to wait — From fifteen conversions, a reported CPA of ₹1,000 could genuinely be anywhere between ₹494 and ₹1,506. Reading it to within 10% takes 384. Most accounts get about four honest evaluation windows a year.
v1.42.010 September 2026

PPC Ads is live

32 lessons on the auction mechanics every paid channel shares, so Google Ads and Meta Ads don't have to teach it twice. A live second-price auction, a four-week campaign with two shocks you didn't cause, and every figure computed by a bit-exact mirror of the engines.

  • Watch the highest bidder lose — Five advertisers, four slots. The one bidding ₹70 never appears; the one bidding ₹32 sits second and pays the least. Then reach position 1 yourself without raising your bid — there's exactly one way.
  • Find out whether you can afford a click at all — Five real-shaped businesses, one ten-minute calculation. Two can advertise, two can't, and one misses by ₹4 — which is a signal to measure properly, not a verdict.
  • Cut a third of the spend in an afternoon — Same customers, ₹28,000 less. The wasted searches cost ₹41 a click against ₹98 for the good ones, which is exactly why nobody notices them.
  • Discover that structure is a price — The same 360 keywords, arranged two ways, differ by 70% in what a click costs. And find out why one keyword per ad group — once the standard advice — is now the wrong answer.
  • Manage four weeks through two shocks — A competitor raises bids on day 11 and a checkout change breaks conversion on day 19. Neither is your fault, both leave different fingerprints, and your choices still change the outcome threefold.
v1.41.010 September 2026

Performance Marketing is live

36 lessons on the economics layer above every paid channel. Twelve simulators, including a deterministic thirty-day campaign engine with a learning phase, creative fatigue and a competitor who turns up on day twelve — and every figure in the course is computed by the same engines you can drag.

  • Run a month of advertising — Choose a creative approach and an audience, and watch thirty days play out day by day. Same budget, same auction — and a 3.5-fold spread in the result from two dropdowns.
  • Find the business losing money on every sale — ₹2,400 an order, growing every month, and ₹484 down on every first order. Learn to compute the break-even ROAS instead of picking a target that sounds disciplined.
  • See what you actually caused — 412 reported conversions. 144 caused. Reported ROAS 2.06, incremental ROAS 0.72 — the campaign lost money. Then find out why most businesses can't run the test that shows this.
  • Discover you should spend a fifth of your budget — ₹50 lakh allocated perfectly still loses ₹13 lakh. The right level is ₹9.5 lakh, and it earns ₹2 lakh. Allocation cannot fix a level problem.
  • Present a quarter in three sentences — Six numbers, one named risk, and a price for the growth you're being asked to buy. Plus the one answer that resolves "how do we know any of this is real".
v1.40.010 September 2026

Social Media Marketing is live

32 lessons on organic social as a system rather than a habit. Fourteen simulators, and every number in the course is computed by the same model you can drag — including the ones that turned out to contradict the standard advice.

  • Find the cliff — Virality isn't a gradient, it's a threshold. Drag the share rate up slowly and reach barely moves — until 1.1% becomes 1.2% and it goes from 400,000 to the whole niche. One tenth of a percent.
  • Price what posting more actually costs — Hold your hours fixed and go from one post a week to seven. Total reach rises 62%. Reach per post falls to under a quarter, and quality per post to 41. Post more is good advice for exactly one kind of account.
  • Beat a creator 150 times your size — A 480,000-follower account has 150x the followers of a 3,200-follower one and about four times the value — and is twenty-one times worse per rupee. Fit multiplies; follower count barely does.
  • Two hours, or seven times the damage — Handle a crisis on the clock. The same excellent response at 72 hours does seven times the damage it would have at two — and a three-minute holding statement beats a perfect one a day later.
  • Report to someone who thinks social is a hobby — Social swings eight-fold across attribution models, more than any other channel. Learn to state the range, name one thing that failed, and offer the test that could disprove you.
v1.39.010 September 2026

GEO is live — getting cited when a machine answers

32 lessons on being one of the handful of sources an AI answer cites. Ten simulators score your writing the way a retrieval system does, live, with every weight shown — so you can see which edit moved it instead of guessing.

  • Watch your paragraph get scored — Edit a passage and watch it move up and down a citation list in real time. Six components, every weight visible, so you learn what actually matters rather than developing superstitions.
  • Beat a source three times your size — A page with a third of the authority of the leader gets cited anyway — because how directly you answer counts roughly twice as much as how authoritative you are. That's the opening this whole course is built on.
  • Find out what machines say about you — One lab has your own homepage losing a question about your own product to a two-line forum comment. It's uncomfortable, it's common, and it takes one sentence to fix.
  • Learn why your measurement is probably too small — To prove your citation rate rose from 20% to 30% you need 294 test questions. Most teams use 30, which can only prove a rise to about 49%. Work out what yours can actually detect.
  • Recognise what not to buy — Nobody can sell you a place in a model's training data or guarantee a citation. One question filters almost every bad pitch in this market, and the course ends by naming which of its own lessons will expire.
v1.38.010 September 2026

SEO is live

36 lessons of search engine optimisation with the folklore removed. Ten simulators, and every number in the course is computed by the same engine you can drag — including the ones that turned out to contradict what we first wrote.

  • Fix a broken site and watch it recover — Crawl a site that lost 74% of its traffic after a replatform, then work out what to fix first. One file is worth more than everything else combined — and until it's fixed, nothing else you do is even visible.
  • Find the clicks you're already losing — Rewrite a search result snippet and watch the click-through rate move at an unchanged position. Ten minutes of writing is worth about as much as climbing a place in the rankings, which takes months.
  • Refresh or write? Price the decision — Forty hours a quarter. Refreshing four decayed pages returns about 6.6 times what writing one new page does — and the split you choose matters more than how well you write.
  • Watch a channel's value swing threefold — Credit the same journeys under five attribution models. Search goes from 20% of revenue to 54% with nothing changing but the model. Anyone quoting one number is quoting a choice.
  • Local search, properly — There's no such thing as position one in local — everyone searching gets a different answer. Find out which 60% you actually control, and which single dropdown is the cheapest fix in all of SEO.
v1.37.010 September 2026

Digital Marketing is live

36 lessons on how marketing actually fits together — diagnosing what's broken before spending, choosing channels by economics instead of fashion, building content and email you own rather than rent, and reading a dashboard without being fooled by it. An analytics simulator runs through the whole course.

  • Diagnose before you spend — Four businesses all say 'our marketing isn't working'. Only one of them actually needs more marketing. Work out which — and learn the habit that catches it every time.
  • See the same data five ways — Credit the same conversions under five attribution models and watch a channel go from worst to best. Nothing about the customers changes — only the accounting.
  • Choose channels by economics — Work out your maximum affordable cost per customer, find where each channel saturates, and allocate a real budget across them. No fashion, no guessing.
  • Finish with a one-page plan — Nine lines including the one nobody writes: what would prove you wrong. It turns a plan from a list of intentions into something you can steer by.
v1.36.010 September 2026

Freelancing is live

32 lessons on the business around a craft — positioning, pricing, finding clients, contracts, delivery, money and scaling. A client-negotiation simulator runs through the whole course: you sit in real conversations, make the call, and see what it costs you. Written India-first, in rupees.

  • Negotiate with real clients — Discovery calls, a scope-creep client who adds five 'small' things, a lowball offer, a rate rise. You pick a response and watch your rate, your scope and the relationship move.
  • A rate floor you can defend — Work out the number below which a job costs you money — including the benefits you now fund yourself and the hours that never get billed. Most people find their first floor was about double their guess.
  • Documents you'll actually use — A positioning statement, a rate card, a proposal, a contract with the six clauses that prevent almost every dispute, a pipeline and a twelve-month cashflow model.
  • Money and tax, explained — Why income arrives in lumps and rent doesn't, how to pay yourself a salary from a buffer, and what GST, TDS and advance tax actually are — with an honest 'use a CA' where that's the right answer.
v1.35.09 September 2026

Finance for Everyone is live

The full course is here — 32 lessons across money, budgeting, debt, the emergency fund, compounding, investing, insurance and retirement. Every number is worked out on screen instead of asserted at you, every model is one you can drag, and it's written India-first in rupees.

  • 32 lessons, 8 practice labs — Each module ends with a lab where you put the ideas through a simulator with a scored goal — budget a real ₹45,000 salary, clear ₹3.2 lakh of debt, build a portfolio and then stress it.
  • Drag the model, watch the answer move — 28 live simulations: compound interest, EMI splits, debt payoff races, retirement gaps and tax slabs. Change one input and the whole picture responds.
  • Six projects that produce something real — A 90-day spending audit, a budget that survives two shocks, a dated debt payoff plan, a protection gap analysis, a goal map, and finally your own one-page financial plan.
  • Written for India — Rupees, Indian tax slabs, EPF and NPS, education inflation, and the products actually sold here — including an honest look at why endowment policies are so widely sold.
  • Education, not advice — No fund, stock or scheme is recommended anywhere. Every projection states its assumptions, and the investing module points you to a SEBI-registered adviser for decisions involving real money.
v1.34.09 September 2026

Lessons you can actually play with

Lessons can now hold live models you drag, charts built from real numbers, and full simulators — an ad auction, a 30-day campaign, a search result, a client negotiation. The first course built this way, Finance for Everyone, is live: budgeting, debt, compounding and net worth, with every number worked out on screen instead of asserted at you.

  • Simulators inside the lesson — Drag a bid and watch an ad auction re-sort. Change a budget and watch a 30-day campaign play out. Move one slider and watch thirty years of compounding respond. The same inputs always give the same result, so you can actually learn cause and effect.
  • New course: Finance for Everyone — Money explained once, properly. Read your own cashflow, build a budget that survives a bad month, understand what interest really costs, and turn a vague goal into a dated number. Written India-first, in ₹.
  • 'Your call' decisions — Some questions don't have one right answer. New decision blocks let you pick a response, see what actually happens, and then read what an experienced practitioner would have done — and why.
  • Jargon, defined where you meet it — Every module now ends with the words that mattered in it — what each one means, and why anyone bothered to name it.
  • Works with motion turned off — Every animation has a still version that teaches the same thing. Nothing is hidden behind a fade — if you've switched off animations, you lose the movement and none of the content.
v1.33.08 September 2026

Pay once. Keep it for life.

We've dropped subscriptions entirely. Basic and Pro are now a single payment — ₹599 and ₹999 — and that's it, forever. No monthly bill, no yearly renewal, and no UPI autopay mandate to approve, so nothing can ever be charged to you again. Every course we publish from here on is added to your account free.

  • One payment, lifetime access — Basic is ₹599 (down from ₹1,199) and Pro is ₹999 (down from ₹2,199). You pay once and every lesson stays open — there's no expiry date on your account.
  • No autopay, nothing to cancel — We don't set up a mandate on your card or UPI, so there's no renewal to remember and no subscription to cancel. Billing & plan now just shows what you paid.
  • Future courses included — Every new course we build is added to your plan at no extra cost — core courses with Basic, everything including the Advanced AI track with Pro.
  • Coupons still stack — Have a code? Apply it at checkout and it comes straight off the one-time price.
v1.32.01 August 2026

Set-up that actually gets to know you

We rebuilt the welcome flow. Instead of a form, it's a short set of questions — including a few that have nothing to do with coding, like what you're into outside of study and which subjects you actually enjoyed at school. At the end, we show you what we understood about you and the courses picked for you, each with a reason. It takes about two minutes, and most of it is skippable.

  • Questions about you, not just code — Tell us what you're into — music, gaming, cooking, art, running a small business. If you've never written a line of code, what you love already tells us where you'd thrive.
  • A learning profile, built for you — At the end we show you what we understood: what you're already good at, how you seem to learn best, and a weekly rhythm that fits the time you actually have.
  • Courses with a reason — Your recommendations now come in order, each with one line saying why that course, for you — connected to something you actually told us.
  • Short, and skippable — About two minutes, a progress bar so you know where you are, and a Skip button on every optional step. You can change any answer later.
v1.31.030 July 2026

Projects, one step at a time

The projects page is now a guided, step-by-step flow. You move through your course projects one at a time with a progress stepper across the top, and each project has a tick-off checklist — check every box and the project is marked complete. It's more visual, more interactive, and it always picks up where you left off.

  • One step at a time — Projects are now a numbered stepper — focus on one project, then move to the next. Jump around freely, and the page resumes at your first unfinished project.
  • Tick-off checklists — Each project's "done when" list is now interactive — check off each requirement as you meet it, and the project completes itself when every box is ticked.
  • Brighter and clearer — A colourful course-themed header, progress that fills as you go, and a little celebration when you finish every project.
v1.30.029 July 2026

Projects you build to get certified

Certificates now mean more. Every course comes with 3–4 hands-on projects to build — real work that proves you can actually apply what you learned. They're not all code: some ask for a written guide, a diagram, or a design doc. Finish the lessons, pass the final exam, and complete your projects to earn the certificate.

  • Hands-on projects for every course — Each course now has a Projects page with 3–4 real-world builds — a starter, a couple of core projects, and a stretch challenge — customized to that topic.
  • Projects count toward your certificate — To get certified you now finish the lessons, pass the final exam, and complete the projects. Mark each one done as you go — you can attach a link or a note to remember what you built.
  • Not just coding — Writing courses ask for a doc, design courses ask for a diagram, command-line courses ask for a transcript — projects fit what each course is really about.
v1.29.024 July 2026

Courses picked for you

Your dashboard now has a “Recommended for you” section — courses chosen from the interests you set during onboarding. We keep the suggestions generous (not just the bare minimum) so you always have a clear next thing to learn, and the onboarding screens got a cleaner, more consistent look.

  • Recommended for you — A new section on your dashboard suggests courses that match the interests you picked — and skips the ones you've already started.
  • Never too few — Recommendations include both the core courses for your path and closely related ones, so there's always a sensible next step — not just one or two options.
  • A tidier welcome — The onboarding screens now use clean, consistent icons throughout for a more polished first impression.
v1.28.024 July 2026

A warmer welcome

The new courses go deeper

We're expanding our newest courses with more lessons, more practice, and advanced topics — plus brand-new interactive diagrams built specifically for each one, so React, Vue, and the rest each get visuals made just for them. Rolling out course by course.

  • React, expanded — The React course now goes from your first useState all the way to custom hooks — immutable updates, lifting state, useEffect cleanup, useRef/useContext, controlled forms, and performance, with four React-only interactive diagrams.
  • Vue, expanded — The Vue course now covers the full reactivity system (ref, reactive, computed, watch), slots, provide/inject, lifecycle, and composables — with four Vue-only interactive diagrams instead of shared ones.
  • FastAPI, expanded — The FastAPI course now goes deep — dependency injection, middleware and CORS, background tasks, async, databases, and testing — with three FastAPI-only interactive diagrams.
  • PostgreSQL, expanded — The Postgres course now covers transactions and ACID, constraints, normalization, and performance — with interactive diagrams for index scans, transactions, and reading a query plan with EXPLAIN.
  • Django, expanded — The Django course now covers class-based views, template inheritance, ORM relationships and the N+1 problem, forms, auth, middleware, and REST Framework — with three Django-only interactive diagrams (MVT flow, ORM→SQL, migrations).
  • System Design, expanded — The System Design course now digs into caching strategies, replication and sharding, CAP and consistency models, rate limiting, CDNs, and SLAs — with interactive diagrams for cache-aside, sharding, and the CAP trade-off.
  • MongoDB, expanded — The MongoDB course now covers query operators, schema-design patterns, compound indexes, the aggregation pipeline, and replica sets/sharding — with interactive diagrams for the document model, embed vs reference, and the pipeline.
  • Redis, expanded — The Redis course now covers all five data types, atomic operations and transactions, pub/sub and Streams, persistence, and eviction — with interactive diagrams for the data types, TTL expiry, and pub/sub.
  • Celery, expanded — The Celery course now goes deep — result backends, retries and idempotency, acks_late, worker concurrency and queues, Canvas workflows (chains, groups, chords), scheduling, and monitoring — with three Celery-only diagrams for the task flow, retries with backoff, and scaling workers.
  • Claude Code, expanded — The Claude Code course now covers the agent loop, its tools, permission modes, plan mode, rewind, slash commands, subagents, hooks, and MCP — with three Claude Code-only interactive diagrams for the agent loop, the tool palette, and permissions.
  • Low Level Design, expanded — The Low Level Design course now covers all five SOLID principles, composition over inheritance, and a full set of creational, structural, and behavioral design patterns — plus a parking-lot worked example — with three new interactive diagrams for classes vs objects, encapsulation, and the Strategy pattern.
  • Microservices, expanded — The Microservices course now covers service boundaries, discovery, the saga pattern, resilience (timeouts, retries, circuit breakers, idempotency), and operations (containers, tracing, independent deploys) — with three microservices-only diagrams for the API gateway, sync vs async messaging, and a saga converging across services.
  • Micro Front-ends, expanded — The Micro Front-ends course now covers the app-shell model, cross-app communication, performance and delivery (shared dependencies, lazy loading, independent deploys), and reliability (fault isolation, contracts, team ownership) — with three new interactive diagrams for team-owned composition, build-time vs run-time, and Module Federation.
  • Web Servers, expanded — The Web Servers course now covers config structure, compression, security (HTTP→HTTPS redirects and hardening), operations (timeouts, zero-downtime reloads), and troubleshooting 502/504 errors — with three web-server-only diagrams for request routing, load balancing with failover, and TLS termination.
  • Every new course, deeper — with its own diagrams — All fourteen of the newest courses now go further (around 18–23 lessons each) and each ships interactive diagrams built specifically for it — over 40 new visuals in total, so no two courses reuse the same generic diagram anymore.
v1.26.07 July 2026

A wave of new courses

We're expanding the catalog with hands-on courses on today's most-used backend, frontend, and architecture tools — each beginner-first, packed with quizzes and playable diagrams, and slotted into the right learning path. Starting with FastAPI, with more rolling out.

  • FastAPI — Build modern, typed Python APIs — path and query parameters, Pydantic request bodies, clean status codes and errors, and a first taste of async.
  • PostgreSQL — Store and query real data with SQL — tables and the relational model, SELECT and filtering, safe writes with transactions, keys and JOINs, plus indexes and JSONB.
  • Redis — Make apps fast with in-memory data — caching, auto-expiring keys, counters and leaderboards, and pub/sub messaging.
  • Celery — Run slow work in the background — define tasks, queue them with .delay(), and add retries and scheduled jobs so your app stays snappy.
  • MongoDB — Store flexible JSON-like documents — collections and CRUD, query filters, embedding vs referencing, and indexes.
  • Claude Code — Pair-program with an AI agent in your terminal — give it context, review its changes, and keep control. Plus a new AI-Assisted Developer path.
  • System Design — Design systems that scale — requirements and estimation, load balancers, caches and queues, replication and sharding, and reliability trade-offs. Starts a new Software Architecture path.
  • Low Level Design — Write clean, flexible code with object-oriented design — the four OOP pillars, SOLID principles, and essential patterns like Strategy and Factory.
  • Microservices — Split a big app into small, independent services — how they communicate over APIs and queues, the role of an API gateway, and the data trade-offs to weigh.
  • React — Build interactive UIs from reusable components — JSX, props and state, lists, events, and effects, plus the 'thinking in components' mental model.
  • Vue.js — The approachable frontend framework — components and templates, reactivity, directives like v-model and v-for, props and events, and the Nuxt ecosystem.
  • Micro Front-ends — Microservices for the browser — split a big frontend across teams, compose pieces at build or run time, and handle shared state, styling, and routing.
  • Django — Build full web apps fast with Python's batteries-included framework — the request flow, URLs, views and templates, the ORM and migrations, and the free admin.
  • Web Servers (NGINX & Apache) — Understand the software in front of every website — serving static files, reverse proxying to your app, load balancing, caching, and handling HTTPS.
v1.25.07 July 2026

Beat the final exam, earn your certificate

Finish a course and a new game-based final exam unlocks — answer questions one at a time, build a streak for bonus points, and score 70% or more to pass. Passing is now how you earn your certificate.

  • A final exam that plays like a game — Ten questions drawn from the whole course, a live score and streak counter, and a results screen that tells you exactly how you did.
  • Certificates you truly earn — Pass the exam to unlock your certificate. Didn't pass? Retake it any time — the questions reshuffle for a fresh challenge.
v1.24.07 July 2026

Start any course over

Want a fresh run at a course? You can now restart it from the course page — your progress for that course resets so you can take it again, and your other courses stay exactly as they are.

  • Restart a course — A new Restart button on each course clears just that course's progress for a clean retake. Your streak and other courses are untouched.
v1.23.07 July 2026

Finished a course? Here's what's next

When you complete a course, we now suggest the perfect next step — the next course in your path, or another great fit — so you never have to wonder where to go from here.

  • A clear next step — Finish a course and a 'what's next' card appears with a recommended course and a one-tap way to jump straight in.
v1.22.06 July 2026

Learning that adapts to you

With your permission, Learners.Center now pays attention to how you learn — the time you spend, how you answer quizzes, and where you get stuck — the groundwork for tailoring your path and recommendations to you. You're always in control: manage it any time in Settings → Privacy.

  • Insights that personalize your learning — We've begun learning how you learn — your reading time, quiz answers, and where you leave off — so we can shape a path that fits you. It records your interactions, never the text you type, and stays private to your account.
  • You're in control — New privacy controls in Settings let you turn learning insights on or off, and opt in to community matching. Turn insights off and we stop collecting and clear anything not yet synced.
v1.21.04 July 2026

Diagrams you can play with

Our concept diagrams are becoming mini-games: resolve a real merge conflict, keep a repo in sync with GitHub, pick the right undo — learn by doing, right inside the lesson. Starting with the Git course and rolling out across every course.

  • Learn by playing — New interactive diagrams give you a goal, let you click and choose your way through, and cheer you on when you nail it — no more just reading.
  • Git, hands-on — Resolve a merge conflict line by line, sync your local repo with GitHub, undo mistakes safely, and predict exactly what .gitignore will hide.
v1.20.04 July 2026

A cleaner, more consistent look

We refreshed the interface around one clean, consistent icon style — across courses, paths, the dashboard, notifications and reminders — so everything feels calmer and more cohesive. Color now comes from our signature pastel blocks, not scattered emoji.

  • One consistent icon set — Course and path badges, notifications, reminders, menus and chips now share a single, tidy line-icon style instead of a mix of emoji.
  • Easier to scan — Cleaner course cards, syllabus and dashboard make it quicker to find your place — the pastel colour-blocks do the pop, the icons stay calm.
v1.19.04 July 2026

Learning reminders that pick up where you left off

Learners.Center now nudges you back to the right place: resume your in-progress course in one tap, or get a recommendation to start when you haven't picked one yet — in the app, and (if you allow) as browser notifications.

  • Resume in one tap — A nudge on your dashboard links straight to the exact lesson you left off on — no hunting for your place.
  • Not sure what to learn next? — When you haven't started a course, we suggest a great one to pick — so you're never stuck at a blank page.
  • Opt-in reminders — Turn on Learning reminders in Settings for gentle nudges to keep your streak going — in the app, and as browser notifications if you allow them.
v1.18.04 July 2026

Notifications — and a Follow button that works

A new notification centre keeps you in the loop: see who followed you, jump to trending courses, and celebrate finishing a course — each with a link that takes you straight there. And the Follow button on public profiles now works reliably.

  • Your notification centre — A bell in the top bar shows your unread count, and a full Notifications page lists everything. Every notification links straight to the action — a learner's profile, a course, or your certificate.
  • Know who followed you — When another learner follows you, you'll get a notification with a link to their profile — so you can follow them back.
  • Trending picks — A weekly nudge points you to a course learners are loving right now.
  • Follow button fixed — Following someone from their public profile now works reliably — and clearly tells you if something goes wrong.

  • Diagrams in chat — When a picture helps, the tutor now drops in one of the module's interactive diagrams right in the conversation — the same animated visuals you see in the lessons.
  • Side-by-side, not on top — On desktop and tablet the tutor now gently shifts the lesson aside instead of covering it, so you can read and chat at the same time.
v1.11.030 June 2026

Meet your AI tutor

Every module now has a built-in AI tutor — tap "Ask AI" on any lesson to get instant, on-topic help.

  • Ask AI, per module — A new "Ask AI" button on lessons opens a chat that knows the module you're studying. It stays on topic, explains things simply, and answers with the same clean cards and code blocks you see in lessons.
  • Focused and fresh each module — The tutor is grounded only in your current module, so its help is relevant. The conversation resets when you move to a new module, and nothing is saved.
  • Tucks in on the side — On desktop it slides in as a side panel so you can keep reading; on your phone it opens full-screen. Suggested follow-up questions keep the conversation flowing.
