PDF markup & review

Mark up drawings together, right in the browser

Upload a PDF, calibrate the scale, and measure, cloud and comment on it with your whole team. Everyone owns their markups; others reply, accept or reject them.

Everything you need to review a PDF

The tools of a desktop markup app, shared with your team and nothing to install.

Calibrate & measure

Set the real-world scale from a known dimension, then measure lengths, circles and areas in feet and inches.

Clouds, arrows & notes

Revision clouds, cloud callouts, leader notes, rectangles and arrows — move, resize, rotate and restyle them.

Replies & stages

Reply to any markup, and accept, reject, cancel or complete it. Authors get notified.

Filters

Show only one person's markups, a category, a stage, a type or a date range.

Shared or private

PDFs are shared with your company by default, or locked to just you.

Export

Download the PDF with every markup as real annotations that Acrobat and Bluebeam can edit.

How it works

1. Upload

Sign up your company, invite your team, and upload a PDF — plans, specs, submittals.

2. Mark up

Calibrate once per page, then measure and annotate. Each person's markups are their own.

3. Review

Reply, accept or reject, filter what matters, and export the marked-up PDF.
