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.

Including your location in the prompt makes results context-aware, with plant choices and materials matched to local climate and architectural style.
