Syllabo is a study app for the IB Diploma, built for the 5 to 30 minutes you actually have. Sessions that choose the content Pick a time and Syllabo picks the content: your weakest syllabus points, the mistakes you haven't fixed and the topics your next test covers. Warm-up, lesson card, recall, application and an exam-format question, then done. Your IB subjects, HL and SL 29 IB Diploma subjects across Groups 1 to 5, from Biology, Chemistry, Physics and both Maths courses to Economics, Business, Global Politics, Geography, History, Psychology, Computer Science, ESS and language courses. More than 53,000 original questions, each tagged to an official syllabus point and given a difficulty level from Warm-up to Expert, with key terms, lesson cards and common misconceptions. Calculation questions come in many versions with different numbers. Marking against the mark scheme Write your answer in your own words. Syllabo marks it against the mark scheme by meaning, not word-for-word, shows which marking points you earned and highlights the ones you missed. If you disagree, you can override the mark. Diagrams you draw Sketch the diagram the question asks for, from supply and demand shifts and externalities to energy profiles, molecular shapes, field lines, hydrographs and curve sketches. Compare it with a model diagram, tick off the marking points, or have AI mark your drawing when you're signed in. Works with a finger, Apple Pencil, or a trackpad on Mac. Your notes, turned into practice Scan or photograph your class notes, paste them, or send a PDF, Word or PowerPoint file to Syllabo. It turns them into flashcards tagged to the syllabus, and with AI switched on, exam-style questions too. Past papers and an exam countdown Questions in IB paper format with command terms and mark allocations. Add your tests and exams, and sessions lean towards what is coming up. Group syllabus points into the units your school actually teaches. An AI tutor that knows your syllabus Ask it to explain, quiz you, mark an answer or set an IB-style question. It knows your subject, syllabus point, mastery and recent mistakes. It works offline from the built-in curriculum, and with an online account it becomes a full AI tutor powered by Claude. Teach it back Explain a topic to your study buddy by typing or speaking, and see which parts you left out. Streaks, skins, leagues and duels Keep a daily streak with your study buddy. Studying earns coins, which open crates of skins for your buddy. Join a weekly league, challenge friends to duels on the same ten questions, and choose exactly what friends can see. Your account on every device Create an account to back up your progress and sign in on iPhone, iPad or Mac, or continue as a guest and create one later without losing anything. Daily reminders are optional. Themes and text size Navy, dark and light themes, and adjustable text size. No ads, no tracking No ads, no analytics and no tracking.
