First set of eyes on every construction drawing.
An invisible audit layer that catches drawing errors before they become rework, delays, and claims. View and manage issues in the tools you already use — drag-and-drop, or audit files directly in SharePoint, Autodesk, Trimble, Procore and more.

PDF in. Audited PDF out. You never leave your tools.
MarkedUp is an intelligent invisible layer inside the tools you already trust. While others provide a "first-pass," MarkedUp provides a final audit.
Step 1: Drop in your PDF set
Upload your architectural, structural, and MEP drawings. We handle the heavy lifting.
Step 2: View your MarkedUp PDF
We export all found issues as standardized markups directly into a PDF opened in Bluebeam, Autodesk, Procore, or wherever you manage PDFs today.
Step 3: Bid and build better
Your team resolves them exactly as they do today, just without the 40 hours of manual searching.

Other tools offer a first-pass. markedup.ai provides a final audit.
Generic LLMs hallucinate, and basic construction AI tools only scan text. markedup.ai reads drawing geometry, symbols, and cross-sheet references — then returns Bluebeam-ready findings.

The story behind MarkedUp.
As a construction engineer, I watched my wifes brother lose $100,000 on a single project because of errors nobody caught. I built MarkedUp so nobody, architect or GC, ever absorbs that loss again.

Headless means markedup.ai works inside the tools you already use. Drop a PDF into ConstructionProof, or connect a folder where your drawing sets already live. markedup.ai runs the audit and returns Bluebeam-ready findings to the workflow your team already knows.
No new system of record. No dashboard to remember. Just findings where your team already works.
ConstructionProof is the drag-and-drop path into markedup.ai. Upload a PDF drawing set, get a scoped integrity audit back, and open the findings where your team already works. The name is the ease pun — so easy it’s construction-proof — not a second product.
