Markup and measure in one place
Twelve annotation tools and eleven takeoff tools on the same sheet, organized on layers, worked by multiple users at once.
Construction plan software
A browser-based workspace for construction plans.
Upload plan PDFs, mark up drawings with a full annotation toolset, measure into cost-loaded categories grouped by room, and connect the field through QR-linked printed plans and the project poster.
Why teams use it
Organized around the sheet set.
Takeoffs in dollars
Categories carry unit costs and rooms group the measurements, so the takeoff reads as an estimate — by category, room, or total.
The whole project attached
Documents, AI-searchable photos, kanban tasks, RFIs, and punch list all hang off the drawing — and off QR tags on the printed set.
FAQ
Common questions
What is Redliner used for?
Construction PDF markup, cost-loaded takeoff, AI version comparison, and drawing-centered project modules: documents, photos, tasks, RFIs, and punch list.
Does Redliner require desktop software?
No. Redliner is browser-first, so teams can work from Mac, iPad, Windows, and the web — and field crews connect by QR with no app install.
Can Redliner import from other markup tools?
Yes. Marked-up PDFs from Bluebeam and other platforms import with annotations editable.
