Markup & Validate is a browser-based review station for AI-generated construction drawing sets. AI can now produce a full drawing set in minutes, but nothing checks the output. Markup tools were built for human-made drawings. Model checkers review the model, not the drawing set that actually...

Markup Validate's answer
Markup Validate's answer
It's the only markup tool with a gated sign-off. Every finding needs a named reviewer and written evidence before it closes, and the sign-off stays blocked while anything is open. "Looks fine" gets rejected by design. Competitors give you redlines. This gives you a traceable review record.
Markup Validate's answer
Bluebeam does markup but has no opinion on your standards and lets you sign off with open issues. Autodesk's tools review the model, not the drawing set that actually gets issued. Markup & Validate assumes AI-made input: a 15-rule AEC standards profile, structured human verification where software can't check, and a sign-off gate. It's the review layer the others don't have.
Markup Validate's answer
BIM managers, QA reviewers, and project teams who issue drawing sets, especially firms starting to produce drawings with AI assistance. Anyone whose signature goes on a set someone (or something) else drew.
Markup Validate's answer
I wrote an article arguing AI tooling for Revit is a bridge and the other side doesn't need Revit. A commenter reframed it: AI does 80 to 90 percent, humans do the correction, and the correction doesn't have to happen in Revit. We already redline in Bluebeam. That comment became the product. I built Markup & Validate in two days around that workflow.
Markup Validate's answer
PHP backend with MySQL, PDF.js for in-browser drawing rendering, vanilla JavaScript frontend, and Stripe for subscriptions and billing.
