I work in BIM and digital delivery. A few weeks ago, I wrote about AI learning to operate Revit through MCP, and my take was: these tools are a bridge. The other side doesn't need Revit. The comments changed what I built. Someone pointed out that AI does 80-90% and the human correction stays in the loop, and the correction layer doesn't have to be Revit. We already redline in Bluebeam. That thread became this product. The problem: AI can generate a drawing set in minutes, and nothing checks it. Markup tools were built for human drawings. So I built a review station for AI output: redline the set, run it against a 15-rule AEC standards profile, and sign off only when every finding has a named reviewer and written evidence. The sign-off stays blocked while anything is open. One thing I'm deliberately honest about: half the rules are human-verification tasks. The software doesn't pretend to certify your drawings. It makes the checking traceable. It's live at markupvalidate.com, free to start. I'd love to know: what rule would your office add?
