For construction project managers
Every revision change — cited, gridlined, ready for a variation claim.
Upload the old drawing and the new one. RevRadar pinpoints every substantive change, quotes the callout text it's based on, and ranks it by impact on your trade — so nothing slips through and nothing's left on the table.

The problem
Revisions are slipping through.
Changes that aren't clouded.
Drafters miss clouds. The rev tag updates but the actual change isn't marked. You only spot it on site — or the RFI tells you.
Hours per set, by eye.
Reviewing multiple drawings against the previous revision takes hours. You still aren't confident you caught everything.
PMs across multiple jobs.
Running three jobs at once, you can't eyeball every sheet against the last revision. The one structural change you trusted the rev cloud to mark becomes an RFI three weeks later — and a cost you're now arguing over.
How it works
Three steps. Same workflow, faster.
Upload Rev X + Rev Y.
PDF only — vector or raster. We vector-overlay native PDFs and pixel-diff raster pages. Drag-drop, pair-by-pair.
Hybrid diff + trade-tuned AI.
Geometry diff finds the changes. The trade-tuned AI tells you which ones matter, in the language of your trade.
Severity by scope of works.
Findings are ranked by how much they affect the work — not by line thickness or pixel area. Export the PDF, sign off, log who reviewed what.
What you get
Every finding, grounded in the drawing.
Every change quotes the actual callout text the AI read off the drawing — cited, gridline-referenced, and traceable. Nothing invented.

Summary of Changes
New 40N12-200 × 3500 reinforcement bar group added at the slab edge.
Bar diameter increased N12 → N16: 4N12-200 x 9300 changed to 4N16-200 x 9000. A new 2N12 bar group also added.
Reinforcement group 2N16-150 (1500mm) and its dimension annotation removed from the slab layout.
Features
Built around how PMs actually review.
Pulls revisions straight from Aconex
Connects to your Aconex project and compares each new revision against the last automatically. No re-downloading every transmittal by hand.
Reads drawings the way your trade does
Each trade gets its own tuned prompt. The model knows a real change from drafting noise — structural reads structural, MEP reads MEP.
Works on every PDF you'll get
Native CAD exports and scanned drawings both — vector overlay where the geometry's native, pixel diff where it's been flattened.
Tells you what to chase first
Every finding ranked High, Med or Low by impact on the work itself — not line thickness or pixel area. The traffic light tells you where to start.
Defensible months later
Prompt fingerprint, model ID and library SHA stamped on every report — so a finding still stands up when the variation's disputed.
FAQ
The short answers.
How accurate is the AI?+
It's a review aid, not a replacement for human verification. Every finding cites the visible text it read from the drawing; flagging a false positive is one click.
How is this different from mbue?+
Two things. RevRadar plugs straight into Aconex, so revisions flow in from the CDE your project already runs on — no exporting and re-uploading. And it's tuned to read drawings in your trade's language, so it flags what actually matters to the works instead of every line that moved.
Does it work with Aconex?+
Yes. Connect your Aconex project and RevRadar compares each new revision against the previous one automatically.
What file types do you support?+
PDF — native vector or scanned. DWG / DXF support is on the roadmap.
Where is my data stored?+
Australian region (Supabase + Fly.io). Row-level scoped per organisation. See our Privacy Policy for full detail.
Who can see my uploads?+
Only members of your organisation. RevRadar staff don't browse customer drawings.
Are my client-confidential drawings safe?+
Your uploads are visible only to your organisation, scoped per-org at the database level, and hosted in Australia. RevRadar staff don't browse customer drawings.
Can I export the report as a PDF?+
Yes. Beta testers have full PDF export during the private beta.
Can I cancel any time?+
Yes — self-serve in the billing tab. No 'contact support' run-around.
Why is it invite-only right now?+
We're in a private beta and letting trades in a few at a time so we can iterate the AI prompts on real drawings. Join the waitlist and we'll email you when your spot opens up.
Private beta · invite-only
Get early access to RevRadar.
We're onboarding a few trades a week so each one gets the AI tuned on the drawings they actually deal with. Drop your details and we'll email you when your spot opens up.
