Pick a subject.
Five cards a day.
Never the same one twice.

Lorearn writes you a small, finishable set of learning cards every day on whatever you want to learn — in your own language, at your own level, remembering everything it has already taught you so it never covers the same ground again.

Start learning — it's free See how it works No signup. No card. Start in one click.

Why it isn't just asking an AI

You could ask a chatbot to teach you something every morning. Three things make that fall apart by week two — and they are exactly what Lorearn is built around.

It remembers

Every topic you have seen is tracked and fed back in, and anything that overlaps is thrown away before it reaches you. A chat has no memory of yesterday, so it circles the same popular ideas over and over.

It climbs

Beginner to expert is a ladder you actually move along, not a phrase in a prompt. Your level, your progress and what you have finished are all kept — so the material gets harder as you do.

It speaks your language

Cards are written in the language you choose, not translated after the fact. If good technical material in your language is thin on the ground, this is the whole point.

What a card actually contains

Not a flashcard and not a definition dump. Each card is shaped the way a practitioner would explain it to you — including the parts most material leaves out.

Database Indexing Intermediate · 3 / 5

Covering indexes

An index that contains every column a query needs, so the database can answer from the index alone and never touch the table itself.

Where it's used
Read-heavy endpoints that select a handful of columns over and over — a listing page, an autocomplete lookup.
When not to use it
Write-heavy tables. Every extra column in the index is another thing to update on each insert.
Common mistake
Adding columns to the index in the order they appear in the SELECT rather than the order the query filters on.

An example of the shape, not a real generated card — yours are written for your subject, level and language, and include code examples where the subject calls for them.

How it works

Three steps, and the third one is just showing up.

  1. Name your subject

    Anything — Kubernetes, Ottoman history, options trading, organic chemistry. Pick your level and the language you want to read in.

  2. Get your daily set

    Five cards by default, however many you like. Small enough to finish, which is the only reason a daily habit survives.

  3. Keep what you learn

    Mark cards learned, save the good ones, take notes, quiz yourself. Your history is yours — export it whenever you want.

Who it's for

Built for people who already know what they want to learn.

Developers going deeper

You ship working code but can't see the shape of what you're missing. The ladder maps it for you.

"I know React. I don't know what I don't know."

Interview preparation

A date, a subject, and limited evenings. Common mistakes and interview angles are on every card.

"System design interview in three weeks."

Learning in your own language

Technical material in Turkish, Spanish, Portuguese and more — written that way, not machine-translated.

"My English is fine. My own language is faster."

What Lorearn is — and isn't

Knowing where a tool stops is part of trusting it. AI writes these cards, and that sets real limits.

Good for

  • Building the concepts and vocabulary of a field
  • Practitioner instinct — when not to use something, what usually goes wrong
  • Systematically covering a subject you already know you need
  • A small daily habit that actually ends

Not for

  • Decisions that matter — medical, legal, financial. Verify before you rely on it
  • Replacing official documentation or primary sources
  • Fast-moving facts like news, prices or release notes
  • Open-ended chat — this is a daily set, deliberately, not a conversation

Questions

Do I need an account?

No. Open it and start — your stacks and cards are saved to your device straight away. Creating an account later keeps everything you have already learned and lets you reach it from your phone too.

Is it free?

Yes, and the free plan is a real one, not a trial. A paid plan for heavier daily use is planned; nothing you have learned will be taken away when it arrives.

Which languages can I learn in?

Cards can be written in English, Turkish, German, French, Spanish, Portuguese and Dutch. The interface language and the language your cards are written in are set separately.

How does it avoid repeating itself?

Every topic you have been shown is remembered and passed back in when new cards are written, then anything that still overlaps — by topic, title or content — is discarded before you see it, and replacements are generated in its place.

Can the cards be wrong?

Yes. They are written by AI and can be incomplete or mistaken, which is why we say plainly that anything you rely on should be verified — particularly in medical, legal, financial or safety-critical subjects.

Can I get my data out?

At any time, in one click, as an encrypted file you can import again later. You can also delete your account and everything in it from inside the app, permanently.
