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.

Automate site plans and test development deals in hours, not weeks
Map any parcel or draw custom boundaries, then generate a buildable plan with road layout, turning radii and topography handled so you avoid redesign later.
Produce optimal surface and structured parking layouts, set custom stalls and drive aisles, and validate parking ratios without manual drafting.
Overlay parcel, environmental and zoning data, model 3D terrain with cut-and-fill analysis, and check power and utilities infrastructure before design assumptions harden.
Connect financial models directly to your design, with live pro forma figures and import of your own Excel templates, to see whether a deal pencils.
