Remember 95% of what you study. Turn YouTube videos, PDFs, and lecture notes into AI flashcards — yours to keep, forever.
Cognito uses Gemini AI to generate exam-ready flashcards from anything you read, watch, or hear. Built on FSRS, the modern spaced-repetition algorithm trusted by medical students, lawyers, and engineers worldwide — sharper than the SM-2 algorithm Anki ships with by default.

Cards that stick longer.
We rewrote the algorithm that decides when each card comes back. It now adapts to your memory in real time — tighter intervals on the cards you know, fewer surprises on the ones you don't.
Also in this update:
• Pick which AI-generated cards to keep before saving — tap any one to skip it
• Weak-areas chips on the Generate screen surface the topics where your accuracy is slipping
• Badge on the icon shows how many cards are due today
Thanks for studying with us.
