Dejavu: AI Flashcards & Chat
Spaced repetition + recall
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Learn anything. AI makes flashcards from any topic, photo, or PDF. Spaced repetition keeps them in your head. 7-day free trial.
Learn anything. Tell Dejavu a topic you want to know, or hand it your photos, notes, or a PDF - the AI builds the flashcards. Then spaced repetition makes them stick.
Just give it a topic. Curious about Roman history, music theory, or Korean grammar? Ask the AI and it builds a deck for you. No homework required.
Or bring your own. Take a photo of your class notes, paste a chunk of text, or import a PDF. Dejavu reads it, picks out what matters, and builds cards from it - no more typing out 100 flashcards by hand.
Spaced repetition does the heavy lifting. Each card returns right before you'd forget it. The algorithm learns how well you remember each one and schedules the next review accordingly. Stuff that's about to slip away gets reinforced; stuff you know cold stays out of your way.
Cram on your terms, too. Spaced repetition is the default, but you can grab any deck and run through it as many times as you want - the night before an exam, on a flight, whenever. No daily caps on review.
