AI document assistant that drafts PRDs, help docs and wikis from a short brief
Describe a problem and a feature, and get a structured first draft you can adapt to your team's PRD template.
Highlight a section and let AI expand, restructure or refine it, with tools like PRD Review that surface gaps before you ship.
Turn a short text prompt into flowcharts, sequence diagrams, Gantt charts and other professional diagrams.
Work in the same document simultaneously, follow edit history, and organize complex documentation in flexible hierarchies.

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.
