ExamTwin: AI Exam Practice

ExamTwin is a personal examiner, not another flashcard app. Upload your own study material — lecture PDFs, slides, Word documents, or just paste text — or start on our built-in demo course, and ExamTwin builds a "Twin": a living map of exactly what you do and don't yet know.

Then you play against it. Every run is a duel: you answer, your Twin answers, and the questions get harder or easier depending on how sure you say you are — guessing right doesn't help you, saying "no idea" doesn't hurt you. Wrong answers open a crack in your knowledge; get the retry right and it seals with gold. Win the boss round, get the five-beat summary, watch your Twin's medals and evolution track what's actually solid.

Written answers get graded by AI, not just multiple choice — and if you disagree with a grade, Challenge it and get a second, independent ruling.

ExamTwin is for students from age 12 up. Under your country's age of digital consent, a parent confirms by email before any material can be uploaded or any account saved — the intake and first challenge work right away either way.

On iPhone you feel every right answer and every "Got you" as a small tap, and ExamTwin can remind you every evening for a three-minute round. Sign-in links from your mail open straight in the app.

No ads. No selling your data. No third-party analytics or trackers. Your uploaded files are deleted the moment their text is extracted; only that text (and your answers) stay, so future questions can point back to where they came from. Full details: examtwin.app/privacy.

Free to use.
