Handwritten notes, PDF markup, and AI study tools on one canvas
Low-latency ink with palm rejection, cross-out to erase, and handwriting-to-text conversion keeps writing close to pen on paper.
Import contracts, papers, or textbooks and mark them up by hand, with searchable annotations and clean exports.
Search across typed text, handwriting, and sketches, and turn notes into summaries, mind maps, or structured plans.
Work together in shared notebooks, documents, and whiteboards simultaneously, without version conflicts or file ping-pong.

Share and access study materials worldwide — with AI study tools built in
Search a vast, student-contributed library of lecture notes, summaries, study guides and past exams organised by course and institution.
Generate notes, summaries and revision material from documents so you can study the essentials instead of re-reading everything.
Turn study material into interactive quizzes and flashcards so you can test yourself and target weak spots.
Use built-in text-to-speech to listen to study documents on the go, useful for revision during commutes or downtime.
