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.
