Stop typing flashcards. Start studying. StuhDee is a spaced-repetition flashcard app built for students who are tired of spending hours making decks by hand. Paste your notes, drop in a PDF, share a link, or snap a photo of your textbook — AI turns your material into clean, study-ready flashcards so you can focus on learning, not formatting. AI that does the busy work Your study material is already there. StuhDee reads it and builds question-and-answer cards for you — the kind you’d actually want to review. No more copying definitions line by line or guessing what to put on the front of the card. • Generate full decks from pasted notes, PDFs, URLs, and images • Get smarter cards with AI suggestions — shorter answers, clearer questions, memory hooks, and splits when a card tries to do too much • Study coach helps when you miss a card — practical explanations and memory tricks, not just “wrong, try again” • Language learning support — translations, native script, examples, and reverse cards for vocabulary and phrases • Weekly AI insights that point you at weak spots and tell you what to study next Spaced repetition that actually works StuhDee schedules your reviews using proven spaced-repetition science (SM-2).
