Turn any lecture into study notes you'll actually remember, then get flashcards, a quiz, a mind map and a podcast from the same note. Snap your class notes, record the lecture, paste a link or type what you have. VisualNote AI writes clear study notes and draws them as a hand-drawn visual page. From that one note you get every tool you need before the exam. HOW IT WORKS • Add your materials: photos of your notebook or textbook, a voice recording (record live or upload one), a web link, or your own typed notes. Mix them in one note. • Pick what to make: notes come first, then choose a visual, flashcards, a mind map, a quiz or a podcast. • Study: flip cards, take the quiz, follow the map, or listen on the way to class. WHAT YOU GET FROM ONE NOTE • Study notes: clean, structured notes written from your materials. • Visual notes: a hand-drawn page in the style you like, from Teen Diary to Blueprint, Comic or Swiss Design. • Flashcards: made for you, flip and test yourself. • Mind map: see how the ideas connect, in a vertical or radial layout. • Quiz: five questions at a time. Every miss comes with the right answer and why. • Podcast: a solo host, two hosts talking it through, a quick-fire drill or a debate, made from your class. • Chat: ask about your notes, get an explanation, or change the notes and the visual. MADE FOR STUDENTS Built for high school and university: lectures, textbook chapters, revision before tests, and exam prep. Visual notes help you remember more than a wall of text, and active recall with flashcards and quizzes is what makes it stick. FREE AND PRO Start free with a set of visuals, flashcards, mind maps and podcast minutes. VisualNote Pro unlocks more of everything, all styles and no watermark. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the period; manage them in your Apple ID settings. AI-generated content can contain mistakes: check important facts against your course materials.
