Any class material becomes a complete study system
ClassFactor turns uploaded class material (PDFs, slides, notes, videos and images) into flashcards, notes, guided lessons, quizzes and timed exams, with an AI Tutor and a Study Coach on top.

01The challenge
Students drown in material, then rebuild the same flashcards and quizzes by hand. Most study apps solve one piece and leave the rest to the student.
The product had to feel simple to a first-year student and still be serious enough for high-stakes exam prep.
02What we built
- Upload anything and generate flashcards, structured notes, guided lessons, quizzes and timed exams from it.
- Question types beyond multiple choice: true/false, written and case-based, with auto-graded timed exams on every plan.
- Spaced repetition on FSRS scheduling, plus image occlusion for diagrams on the Pro plan.
- An AI Tutor that explains step by step from the student's own class material, and a Study Coach for plans, reminders and weak-area insights.
- Mastery analytics, a path for educators, clear pricing, study guides and a blog.
03What they have now
One upload produces a whole study system instead of a single deck.
Students see what they know, what to focus on and how they're improving over time.
Core features are free to start, with no credit card, and study material stays private.
