Why it works

Built around the forgetting curve

Most of what you read is gone within days. CourseBox is designed to interrupt that — turning a one-time lesson into lasting memory.

Recall over 30 days

100%0%≈90%≈10%D1D3D7D14D30
With timed reviewsLeft to fadeMemory kept

Memory fades fastest right after you learn something. Two well-studied techniques flatten that curve, and both are built into every course.

01 / 02

Active recall

Every lesson ends by making you retrieve the idea instead of rereading it. The effort of remembering is what builds durable memory.

02 / 02

Spaced repetition

Flashcards return on a widening schedule — a day later, then a few days, then weeks — catching each idea just before it slips.

Comparison

Why not just a chatbot or a video course?

General AI tools and off-the-shelf courses each solve part of the problem. CourseBox is built end-to-end around remembering.

FAQ

Frequently asked questions

Everything you might want to know before you start.

01How long does it take to generate a course?

Your outline appears in about a minute, then lessons are generated one by one in the background — you can usually open the first lesson within a couple of minutes while the rest of the course builds.

02What topics can I learn?

Almost anything — from machine learning to history to a new language. If you can describe it, we can build a course around it.

03Do I need to pay to start?

No. You can create your first course for free, with no credit card required.

04How does spaced repetition work?

Flashcards from your lessons are scheduled to reappear right before you'd forget them, so knowledge sticks for the long term.

05Can I share a course with someone?

Yes. Any course can be made public with a read-only link — anyone can open the lessons, while your progress, flashcards and bookmarks stay private.

06Which languages are supported?

You can generate and study courses in English and Russian today, with more languages on the way. Just describe your topic in the language you want to learn in.

07How accurate is the AI-generated content?

We use the latest large language models and structure every course for clarity, but AI can still make mistakes. Treat it as a fast, well-organized starting point and verify anything critical.
