Derive Notes is a canvas-first note-taking app built for math, science, and engineering students. Write equations by hand with Apple Pencil, and let Derive understand what you wrote, so your notes do more than sit on the page. HANDWRITING THAT'S ACTUALLY UNDERSTOOD Draw on an infinite canvas the way you would on paper. Derive recognizes your handwritten math as you work, turning messy strokes into clean, structured expressions you can check, reuse, and build on. A TUTOR RIGHT NEXT TO YOUR WORK Stuck on a step? Open the tutor panel and get step-by-step help tied directly to what's on your canvas. It works alongside your handwriting instead of pulling you into a separate app. BUILT FOR REAL STUDY SESSIONS - Infinite canvas with smooth, low-latency inking - Pen, eraser, and lasso tools for fast editing - Organize your work into notebooks and pages - Two-finger tap to undo, pinch to zoom - Your notebooks sync securely across your devices DESIGNED FOR FOCUS A clean, distraction-free workspace with light, dark, sepia, and high-contrast themes, so long study sessions stay comfortable. Derive Notes keeps your handwriting at the center and adds just enough intelligence to make studying faster by recognizing your math, helping you through hard steps, and keeping every page organized and in sync. Note: Derive uses trusted third-party AI providers to process handwriting and page text for recognition and tutoring. You're asked for consent in-app before these features are used. DESIGNED FOR IPAD AND APPLE PENCIL Handwriting, drawing, and the full authoring tools require an iPad with Apple Pencil. On iPhone, Derive is a companion for reading and reviewing your notebooks: browse your library, open any page, search across everything, and ask the tutor. Notes you write on iPad appear on iPhone automatically. SUBSCRIPTION Derive Pro unlocks writing and editing, handwriting recognition, and the AI tutor.
