Revision that remembers what you're weak on.
Turn your lecture PDFs, slides, and photos into AI-graded quizzes and a notebook that tells you exactly what to study next.
No spam, ever. One email, the day your invite is ready.
See it in action
From lecture to AI-graded quiz to a smart review queue — the whole loop, start to finish.
Upload once. Study smarter every time after.
No flashcard decks to build by hand. No re-reading the same 40 slides before every exam.
Upload a lecture
Drop in a PDF, a set of slides, or a photo of the whiteboard — StudyStack reads the diagrams too, not just the text. Confirm the credit estimate and it processes in seconds.
Get AI-built notes
Your lecture comes back as clean, structured notes — key concepts, definitions and testable facts, with the important diagrams pulled straight out of the slides. Nothing to organise by hand.
Take a graded quiz
AI-written questions from your own material, graded the moment you submit — not just right or wrong, but a specific explanation of what you nailed and what you missed.
Review what you got wrong
Every weak answer is saved and resurfaced on a spaced-repetition schedule — so the gaps close before exam day, right when you'd otherwise forget them.
Built on your lectures, not the open internet
The more you upload, the more StudyStack notices — patterns no flashcard app or general AI chat can see.
Ask AI, grounded in your notes
Answers sourced from your own lecture concepts — never the open web.
Adaptive spaced repetition
Weak answers are quietly rescheduled so gaps close before exam day.
