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.

AI takeoff and estimating software built around real construction drawings
Automatically detects and measures rooms, walls, doors, windows and custom areas, assigning each element a name, type and ID, with a second review pass that re-fits outlines against the drawing.
Point at a single element and AI locates and counts every matching object across all pages of a drawing, grouping similar elements separately for accurate quantities.
An in-platform agent that reads drawings, executes measurements and returns exact quantities, with visible steps and approval gates for critical actions.
A no-code visual designer for compiling, testing and publishing repeatable estimating playbooks, plus ready-made skills such as CountFlow and Excel Template Builder.
