When you upload files, the app extracts the text needed to build your cards and then discards the files immediately. Nothing is written to permanent storage and we keep no copy of your documents.
When you turn on AI, the text of your selected topics is sent securely to our AI provider so it can write questions and suggest related topics. This only happens while AI is switched on. With AI off, nothing is sent anywhere — the cards are made on the server and returned to you.
This test version has no login and no saved decks. Once you leave, nothing about your session remains. To keep your cards, use the Export buttons (Anki, CSV, or PDF).
Use study material and notes only — please don't upload anything confidential, personal, or sensitive.
