For construction project managers
Spot every drawing revision in minutes, not hours.
Upload two revisions. RevRadar pinpoints the substantive changes — discipline-tuned, with a human-verifiable audit trail.
AI-assisted review aid · independently verify findings.
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 multiple jobs at once, you don't have time to review every drawing yourself. RevRadar does it for you.
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 discipline.
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.
No hallucinated dimensions. Every change is tied to actual callout text the AI read from the drawing — quoted, cited, and traceable.

Summary of Changes
A slab penetration has been added, and an existing concrete wall over has been extended.
New reinforcement bars (40N12-200 × 3500) have been added, with a typical dimension of 1500mm.
Two live-end anchorages have been modified in their geometry — specifically the square outline representing the anchorage body.
Features
Built around how PMs actually review.
Hybrid vector + raster diff
Both flavours of PDF in one pass — vector overlay where the geometry is native, pixel diff where it's been flattened to raster.
Trade-tuned AI
Each trade gets its own AI prompt, tuned to how that trade reads drawings. The model knows what's a real change vs drafting noise.
Severity by scope of works
Every finding is ranked High, Med, or Low by impact on the work itself — not by line thickness or pixel area. The traffic light tells you what to chase first.
Compliance-grade audit trail
Prompt fingerprint, model ID, library SHA stamped on every report. Reproducible months later.

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.
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.
Can I export the report as a PDF?+
Yes — on Growth and above.
Can I cancel any time?+
Yes — self-serve in the billing tab. No 'contact support' run-around.
