Get your first deckAdd a PDF, slides, a Word document, photos of your notes or a recording. Peter reads all of it, works out what matters and builds a path of short sessions — with questions written from your material, so you study what your course actually covers.
Ask your own notes
Students are using Peter to study from their own lecture notes and slides. Here’s what they’re saying.
Yes. Peter writes only from the material you give it. Every question, flashcard and answer comes from your own slides, notes or recording, and carries the page it came from, so you can check the source in one tap. If it isn’t in your material, it isn’t in your study set.
Peter works only from the file you give it. Every question and answer points to the page or moment it came from, so you can check it — and instead of one long chat, you get a structured path of sessions and flashcards to work through.
Your material is used only to make your study set, and never to train AI. There are no ads and no tracking. Recordings are transcribed on your device, and deleting your account deletes your library.
If you study from lecture slides, readings, notes or recordings — at school, at university or for a professional exam — Peter was built for you. It turns what you already have into something you can work through.
PDFs, photos of your notes, Word, PowerPoint and Excel files, audio and video, and recordings you make in the app. One file becomes one study set.
Turn your next lecture into a study set you can trust — and walk into the exam knowing where every answer came from.
