The gap

Bluebeam was built for a 200-person GC. You're not that.

"We just need to redline a plot plan, measure a setback, and know who fixed what — not a Windows license, a training course, and a seat for every sub who touches the file." — roughly every small firm we've talked to

What it does

Everything a review needs. Nothing it doesn't.

Redline in the browser

Freehand markup, survey stamps, and callouts — no install, works on Mac, Windows, or an iPad on site.

Measure & calibrate

Scale the sheet once, then measure distances and areas directly on the drawing — the tool the general markup apps skip.

Built for your org chart

Admin, PLS, PM, drafter — roles that match how a survey or drafting firm actually reviews work.

Every markup, tracked

Nothing gets marked resolved without a name and a timestamp attached — so "still open" always means something.
