Use pressure-sensitive ink, a highlighter and erasers. Palm rejection keeps pen strokes separate from finger scrolling and zooming.
Select your writing with the lasso and choose Recognise. AI can transcribe handwriting, identify formulas and open a function in a coordinate plane. Check the result before using it in your notebook.
Import PDFs and images, or open a document beside your notebook. Keep annotations with the material they belong to.
Insert coordinate systems, functions, matrices and geometric shapes. Edit them afterwards; explore derivatives, tangent lines and points on a graph.
Group notebooks by subject and folders. Find them through search, tags, recent items and favourites, and export backups when you need them.
Group the steps of a worked exercise with labels explaining what each part does. Write them yourself or ask AI for suggestions, then use them to revise the procedure.
