How it works

Three steps to remember anything

AI builds your plan

We extract the key concepts and turn them into flashcards and adaptive quizzes.

03

Lessons arrive on your schedule

Cards drop into your chat at intervals tuned for long-term recall.

The science

Your brain forgets 70% in 24 hours

In the 1880s, Hermann Ebbinghaus discovered the forgetting curve — without review, most information is gone within a day. Spaced repetition flattens that curve by surfacing concepts just before you'd forget them.

Memodrop turns this proven technique into something that fits your life: a few cards in your WhatsApp, exactly when your memory needs them.
