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.

Collaborative decision-making software that helps teams ideate and prioritize faster
Let people contribute ideas without attribution to increase psychological safety and reduce hierarchy bias in brainstorming.
Score each idea on value and effort so the team can spot quick wins and high-impact projects at a glance.
Generate starting ideas against a project goal and let AI rephrase, group or refine existing ideas to speed up sessions.
Ideate and prioritize on your own schedule instead of booking another synchronous meeting.
