For students who are done rereading
Your notes,
turned against you.
Recall reads what you upload — typed or handwritten — and builds eight study games that quiz you on it, catch what you're confidently wrong about, and resurface what you're about to forget.

How it works
From a messy PDF to knowing it cold, in three moves
1.Drop in your notes
PDFs, docs, slides, photos of handwritten pages. Processing runs in the background while you watch it work.

Finding concepts…
2.Recall maps the material
Concepts, definitions, formulas, dates, and how they connect — every single one linked back to the page it came from, so nothing is invented.
"…the proton gradient drives ATP synthase…" — your notes, p. 12
3.Play until it sticks
Eight games drill the same material from different angles. One mastery model watches every answer and steers you at what you don't know yet.

The games
Eight ways to attack the same material
Different angles keep mastery honest — recall, matching, connections, error-spotting, application.
Sam studies from your notes — and gets things subtly wrong. Catch the errors, then teach the fix.
Erroneous-example learning + the protégé effect, as a chat
Three lives, rising difficulty, personal bests.
Five timed minutes on what the model says you need most.

Rebuild how your concepts link — cause, part, contrast.

The engine
One mastery model watches every answer — and it doesn't forget that you do
Spaced repetition
Recall at the right moment counts more, and pushes the next review out.
Confidence calibration
Confidently-wrong answers get flagged as misconceptions and hunted down.
Forgetting curve
Mastery decays between sessions, so stale knowledge resurfaces on its own.
EVERY CONCEPT'S JOURNEY
Weak concepts surface more often. Mastered ones come back just before you'd lose them.

FAQ
Fair questions
More detail — including how we treat AI accuracy and your data — lives in the full FAQ, Terms and Privacy Policy.
What counts as an AI credit?
Only the moments AI does heavy lifting: processing a document (5), a tutor answer (1), a flashcard deck (3), exam predictions (5), review notes (2), a case-study scenario (3). Playing the games is unlimited on every plan.
How does the free trial work?
Pick any plan and you get 3 days with its full credit allowance before the first charge. Cancel during the trial from Settings and you pay nothing.
Does handwriting really work?
Yes — photos of handwritten pages are transcribed with vision AI before extraction. Clear handwriting works best.
What happens when credits run out?
Nothing you've built goes away. Games, flashcards, concepts, and progress keep working — new uploads and tutor questions wait for the monthly reset or an upgrade.
Is there a mobile app?
Yes — all eight games, uploads from your phone, flashcards, and the tutor, synced to the same account and streak.
Can I cancel anytime?
Anytime, from the billing portal in Settings. Your data stays either way — AI features just pause until you resubscribe.
Your next exam is coming either way.
Upload one set of notes and see what Recall finds in it — three free days is more than enough to know.
