Retentit

Remember what you study.

Retentit turns your notes into recall practice and schedules each card for the moment you're about to forget it.

Recall first

Every card asks you to remember before it shows the answer. That effort is what makes memories stick.

Spaced for you

Reviews are scheduled with FSRS, an open spaced-repetition algorithm, so short daily sessions go a long way.

Notes and cards together

Outline a subject as a tree of topics and turn any line into a card with "question :: answer".

Draft with AI, if you want

Paste notes and Claude drafts recall questions. You review every one before anything is saved.

Progress that means something

See how well cards hold after a week or a month, and whether your confidence matches your recall.
