Your material never leaves your hands

Every other AI flashcard app uploads your notes to a server. Cerebri doesn't have one.

There is no Cerebri server. Flashcard generation, the AI tutor, handwriting recognition and lecture transcription all run on your device using Apple Intelligence. Nothing you import is uploaded — not your notes, not your recordings, not your questions.

No account. No tracking. No analytics. Works fully offline.

What it does

Capture anything

PDFs and Word docs, photos of handwritten notes, or a recording of the whole lecture. All converted on-device.

Spaced repetition

The proven SM-2 algorithm schedules each card just before you'd forget it. Skip what you know.

A tutor with no usage cap

Miss a card and get a clear explanation instantly. Go deeper with a tutor that knows your whole deck — unlimited, no per-question fees.

Study sheets that are yours

Export any deck to Quizlet, Anki, or a printable PDF — with your saved tutor explanations printed under each answer.

What's free, what's paid

One payment unlocks everything, permanently. No subscription, no per-scan fees, no AI usage limits.
