How lezrn works

lezrn turns anything you want to learn into a course you can actually finish. You bring a subject, a file or a question. lezrn writes the lessons, gives you tools to practice, and brings ideas back at the right time so they stick.

The building blocks

Topic

A home for one subject, like “Organic chemistry” or “Spanish for travel”. It holds your courses, chats, sources and everything the tools make.

Course

A path through the topic, split into chapters and lessons. One topic can hold several courses.

Lesson

A short read of a few minutes. It is written the first time you open it, with pictures where they help.

Concept

One idea a lesson teaches. Concepts are what quizzes test and what Review brings back.

Source

A PDF, document, web page, YouTube video or pasted text you add. Sources steer what gets written.

Credits

The one balance every AI action uses. Buttons show the price before you click.

A typical study loop

1. 1Make a topic with New topic, or type what you want to learn on Home.
2. 2Read the lessons in order. Tap Upbrain or Downbrain on a page so lezrn knows what landed.
3. 3Practice with a tool like Quiz, Flashcards or Blurting from the Tools panel.
4. 4Come back to Review each day. A few minutes keeps your streak and your memory going.
