Most AI flashcard tools lock generation behind a paywall or limit you to one AI model. Flashcard AI is different — it's completely free with a built-in API key, has zero sign-up required, and lets you pick from 7 AI models including DeepSeek, GPT-4o, and Gemini. Upload a PDF, paste your notes, or even snap a photo of your textbook — flashcards come out in seconds. STEM mode generates problem→solution→answer cards. Arts mode makes concept→definition cards with memory hooks.
I'm a college freshman who spent way too many hours manually making flashcards after every lecture. One night I pasted my bio notes into an AI just to see what would happen — and got 25 decent cards back in 30 seconds. That moment made me realize: the grunt work of card-making should be automated, not the actual studying.
Built this over a few weeks with AI assistance (ironic, I know). It's completely free — there's a built-in API key so you can start generating immediately. If you want to use your own key for GPT-4o or Gemini, that works too.
Would love feedback from other students — what breaks? What would you change?
