Every tool the red pen had
Clouds, callouts, highlights, free draw — plus a snip tool that cuts a section of the drawing, pastes it where the conversation is, and rescales it.
Plan markup
The full redline kit, in the browser.
Line, square, circle, polygon, free draw, cloud, text, callout, highlight, tag, image insert, and snip — organized on layers, on the same drawing your whole team works at once.
Why teams use it
Organized around the sheet set.
Layers keep it readable
Annotations and takeoffs live on layers you toggle on and off. The architectural review and the estimate coexist on one sheet.
Multi-user on the same drawing
Several people mark up and measure the same sheet at the same time — no file locking, no emailing versions around.
FAQ
Common questions
What markup tools does Redliner have?
Line, square, circle, polygon, free draw, cloud, text, callout, highlight, tag, insert image, and snip & paste — all in the browser.
Can I import markups from other software?
Yes. Annotations from Bluebeam and other platforms import editable, so existing marked-up sets keep working.
Can field teams view markups?
Yes. Share a live link to the drawing and anyone can watch markups land as they happen — no desktop software, no account required to view.
