Archi Check
Archi Check is purpose-built quality-control software for architectural drawing sets - lighter than a full PDF suite and simpler than a BIM platform. It runs one clear loop: Check, Correct, Verify, Close. Every markup becomes a tracked comment with a unique ID, an assignee and a live status, giving a complete audit trail of every markup, response, assignment and status change. A two-screen workflow shows the drawing full-size on one monitor and the comment register on the other. Markup tools include pins, rectangles, revision clouds, arrows, highlights, freehand, text, callouts and status stamps. Five role-based permissions keep responsibilities clear. QC data stays in your own project folders (OneDrive, SharePoint or network) with no cloud sync of comments, and it works offline. Non-destructive exports produce marked PDFs and registers (XLSX/CSV). Windows today; macOS included with purchase.

Caliente AI
Caliente AI is a copilot for takeoff. Our AI model reads your drawings and does the measuring, right inside the tools you already use. It works in Bluebeam Revu today, with PlanSwift and Autodesk Revit next. It asks before it writes, and every markup it draws is native and editable.
