Upload once. Study your way. ClassFactor turns your notes, PDFs and lectures into guided lessons, flashcards, quizzes and timed exams, then tells you what to study next. Start with 25,000 free AI credits. More than flashcards: ClassFactor is a complete AI study system built around your own material. Add your notes, PDFs, slide decks, lecture recordings or photos of handwritten pages, then create what you need. GUIDED LESSONS Turn a chapter, a slide deck or a lecture into a guided lesson that walks you through the material section by section. Learn it first, then go straight into flashcards or a quiz on the same content. CLEAN NOTES Get clear, structured notes from a PDF, a slide deck or a lecture recording, ready to study from or turn into anything else. AI FLASHCARDS ClassFactor reads your material and writes the cards for you, based on your content and your course, not someone else's deck. No more making flashcards by hand. QUIZZES AND TIMED EXAMS Turn any set of notes into a quiz or a timed practice test: multiple choice, true/false and written answers. Set the length and difficulty, retake it, and see which topics still need work before exam day. AI TUTOR THAT KNOWS YOUR MATERIAL Stuck on a card? Ask why. Got a question wrong? Ask what you missed. The AI Tutor answers from the content you uploaded, so every explanation stays tied to what your class actually covers. AI STUDY COACH Tell the Coach your subjects, your habits and your real exam dates. It builds a study plan you can follow, checks in daily, reminds you when cards are due and tells you what to focus on today. SPACED REPETITION THAT RUNS ITSELF Cards come back right before you would forget them. Missed cards return in the same session until they stick. Just open the app and review what is due. TRACK YOUR PROGRESS Streaks, topic mastery and quiz history show what you know, what to focus on and how you are improving.

Miles takes the notes. You pay attention. Start Class Mode when the lecture begins. Miles puts on his headphones, keeps track of what your professor says, and keeps the distracting apps you choose locked until class ends. Calls always get through. When class is over, Miles hands you your notes: • A clear summary of the lecture • Key notes with when each topic was discussed • Exam mentions and important callouts • Key terms and to-dos LOST FOR A MINUTE? Tap "I'm lost" and Miles catches you up on the last few minutes. Have a question but don't want to raise your hand? Ask Miles during class. He answers using what your professor has said so far, without leaving Class Mode. STUDY MODE Studying on your own? Miles locks the same apps while you study. The mic stays off. • A timer (25, 50 or 90 minutes, or until you stop) or Pomodoro rounds with breaks • Your apps unlock by themselves for each break and when the session ends • Studying for a class? Its notes are one tap away • See your focus time for the week, in class and studying, and a streak that counts both MADE FOR REAL SCHEDULES • Add your classes from a screenshot of your schedule • Get a heads-up before class: "Physics starts in 5 minutes. Ready to focus?" • Choose how strict Miles is, in class and while you study: from no way out to a few emergency unlocks YOUR NOTES ARE YOURS Review your summaries, key notes and transcripts anytime. Export them to study with your favorite AI chatbot, your notes app, or whatever works for you.
