Knowledge layer that gives your AI the context it lacks
Save highlights and insights from webpages, PDFs, videos, social posts, newsletters, Kindle, and email using a browser extension or mobile capture.
Let AI suggest structure, group related insights, and use knowledge triggers and chat to keep your base tidy and searchable.
Feed your stored knowledge to any frontier model or custom agent via an AI Canvas and native MCP, so your context travels with you.
Build a common context space that both people and AI agents draw on for research, feedback, and collaboration.

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.
