How it works
Create an exam with your AI.
Share your material or a topic with ChatGPT or Claude. Connect it to Shadow Study and it saves the exam straight to your library, or paste the exam in yourself.

Learn from your results.
Every attempt goes into your history. Your Dashboard shows what you miss repeatedly, how often you practise and what to review next, and can prepare a summary of your mistakes for your AI to turn into a study plan.

What Shadow Study does not do
- It makes no AI calls of its own. The AI work happens in your own ChatGPT or Claude account. If you connect one to Shadow Study, it can read your exams and results only with your permission, and you can turn that off in your profile at any time.
- It never creates or processes images, audio or video. Exams are text, with tables and formulas.
- Signing in with Google or Microsoft only identifies your account: Shadow Study receives your name, email address and profile picture, and reads nothing else from that account.
