Upload slides, PDFs, Word or PowerPoint files, scan your notes with the camera, add photos, or paste a YouTube or web link. You can also just type the topics of your course. Bo, your study buddy, reads all of it. Then you pick what you need: - Flashcards with spaced repetition - Quizzes with instant feedback and timed mock exams - Study guides, summaries, reviewers and Cornell notes - Cheat sheets, mind maps and labelled diagrams - Image occlusion cards from the diagrams in your files Start with a short placement check. It shows which topics you already know and where your gaps are. Bo then plans every day until your exam, with a topic and a material for each session. Your course start shows what to study today. Stuck somewhere? Ask Bo. Bo explains from your own notes and shows you the page the answer comes from. Study together: share a course with a link. Everyone who joins studies it with their own progress. Export your material as PDF, Word or an Anki deck. For iPhone and iPad, in light and dark mode, with a widget for today's session.
