One editor for the whole set
Upload a drawing set. Mark it up, measure it, compare revisions, and share it — without leaving the browser.
A complete markup toolkit, in the browser
Revision clouds, callouts, arrows, highlights, approval stamps, and text — on any PDF. Apply a markup to one sheet or push it across all 300 at once. Every markup is stored as structured data you can filter, layer, and export. Nothing is burned into the file.
1.0Markup
Calibrated measurement, built in
Set the scale from a preset or a known dimension, then pull lengths, areas, perimeters, and counts straight off the sheet. Cost codes ride on every measurement, knockouts net out of their areas automatically, and quantities export to Excel ready to price.
2.0Measure
See exactly what changed between revisions
Overlay two issues of a sheet and every difference is highlighted — moved walls, new openings, changed dimensions. Version history keeps every issue of every document, so nobody builds from an old set.
3.0Compare
Share the whole set with a link
Send a view link and anyone opens the current set in their browser — no account, no install, no seat. Send an edit link and a sub or architect is set up to draw in seconds. The field, the office, and the client are all on the same drawing.

One current set, reachable from anywhere — with an assistant on it.

Fast in any browser
Tiled rendering keeps full-size drawing sets smooth — on the office workstation, the trailer laptop, or an iPad. Nothing to install, nothing to update.
