PDFViewer AI— a simpler Bluebeam, free to start
Read, Measure & Mark Up Construction PDFs in Your Browser
“Every person who touches a drawing shouldn't need a Windows license to do it. Reading and marking up a plan set is the most common job in construction, and it was locked behind a desktop seat. We built PDFViewer AI to open that up: any plan, any device, free to mark up.”
Al DramFounder of Blueprints AIEx-Planning CommissionerWhy PDFViewer AI?
Read, mark up, and measure construction drawings in your browser or on iPad — the essential Bluebeam workflow, simplified and free to start.
Runs in Your Browser
Open a plan set on any device — nothing to install, no Windows required, no per-seat license.
iPad + Stylus
Mark up drawings by hand with an Apple Pencil — in the office or out in the field.
Free to Start
Open, view, and mark up PDFs for free. Upgrade only when you need measure and takeoffs.
Everything You Need to Mark Up a Sheet
The everyday toolkit for construction drawings — markup, measure, takeoffs, and compare, all in the browser.
Markup & comments
Highlights, text, callouts, shapes, revision clouds, and stamps — with threaded replies.
Measure to scale
Calibrate to the drawing scale, then measure length, area, and angle.
Quantity takeoffs
Count and total quantities right on the sheet — no spreadsheet juggling.
Compare revisions
Overlay two versions and see exactly what changed between them.
Fill & sign
Complete and sign forms, RFIs, and submittals, then export a flattened PDF.
Cloud collaboration
Share a sheet by link and mark it up together in real time.
Open, Mark Up, Share
Three steps, no install. Drag in a plan set and start working.
Open any PDF
Drag a plan set into your browser or open it on iPad. Multi-sheet sets stream fast — no install, no account needed.
Mark up & measure
Annotate with the full markup set, measure to the drawing scale, and run quantity takeoffs right on the sheet.
Share or export
Send a markup link to collaborate in real time, or export a clean, flattened PDF to hand off.
Built for the Field and the Office
What teams using PDFViewer AI say.
We were buying a desktop seat for everyone who touched a drawing. PDFViewer AI opens the same plan set in the browser, marks up on the iPad in the field, and the takeoffs are right there — for a fraction of the cost.
It opens our whole drawing set instantly on the iPad — the super marks up sheets on site without a laptop.
Takeoffs in the browser saved us buying another desktop seat for every estimator.
Revision overlay caught a wall that moved between addenda — that alone paid for Pro.
