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.
