Plan viewer

Full markup: revision clouds, highlights, arrows, formatted text and shapes
Undo/redo, multi-select and copy/paste across sheets
Original PDF layers preserved and toggleable
Resumable uploads — big sets without fearing jobsite wifi

Calibrated measurement

Length, area, volume and angle directly on the sheet
Scale per sheet or per detail, in architect's notation (1/8″ = 1′-0″)
Per-vertex handles: the value is always what the shape says now
Printed sheet size visible, to catch half-scale prints

AI counting

Vector counting: finds every exact copy of a repeated symbol
Vision pass for scanned plans
Review card: you approve or reject each proposed detection
Reports what it could not classify — never silence

Connected takeoff

Every approved count and measure feeds the item log
Adjust a measure and the line item recalculates itself
CSI division profiles: which sheets to review and what to look for, per trade
Estimated cost visible before every AI run — no surprises
