Spaced repetition · Bring your own model
Cards that come back right before you forget.
Name a topic or drop in a file. The AI model you choose writes the deck and a study note. Spaced repetition does the rest.
Bring your own API key. No credit card.
How it works
Three steps, then it runs itself.
Add a file or a topic
Drop in a PDF, a DOCX, or plain notes, or just name what you're studying.
Your model writes the deck
Cards, hints, and a study note, from whichever AI provider and model you pick.
Study on a schedule
Rate each card and spaced repetition brings it back right before you'd forget it.
Works with your key from

Free to use
Your key, your model, your deck.
