ClassNotes

Read full description

ClassNotes is a handwriting-first notebook for iPad, built so what you write is exactly what stays on the page. WRITE, DON'T FIGHT YOUR APP Your Apple Pencil ink is recorded exactly as you draw it — no smoothing, no reshaping, nothing "cleaned up" behind your back. Turn on live beautification only if you want your handwriting typeset as you go. SMART TOOLS, ON YOUR TERMS • Hold a shape steady and watch it snap into a clean line, circle, rectangle, or triangle — still adjustable until you lift the pencil • A real two-finger ruler for straight edges • Paint bucket fill that flows under your ink, not over it • Scribble to erase • Sticky tape, text boxes, and photo/file drops • Full undo/redo history, per page NOVA, YOUR AI STUDY PARTNER Circle anything — a diagram, an equation, a paragraph — and ask NOVA about it. It sees exactly what you circled, not just the text, so it can actually explain a graph or work through the diagram you drew. MADE FOR NOTEBOOKS 28 cover designs, 14 paper templates, custom paper and line colors, multiple page sizes and orientations, and a dedicated whiteboard page for freeform sketching. FIND ANYTHING Search across typed text and your own handwriting — even pages you never touched with a keyboard. STAYS IN SYNC Signs in with your ClassMate account. Notebooks, pages, and attachments sync automatically, and pages you write on iPad show up — searchable, zoomable — right in the ClassMate app. READ ANYWHERE The iPhone companion app is a fast, read-only viewer for your whole library — perfect for a quick look between classes. Free to use. No paywall on the notebook.
