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.
Capture your ideas, then swipe to see which ones really matter
Capture thoughts instantly with a simple interface so nothing is lost; ideas drop straight into your evaluation flow.
Evaluate ideas like a dating app — swipe right to upvote, left to discard — for repeated, mood-independent judgment.
Organize ideas in lists, apply filters and track status, then mark winners as 'to implement' when it's time to decide.
Come back regularly, add new thoughts and let ideas grow and develop over time rather than stall after capture.
