Catch it in review.
Not in the field.
Upload a plan set and a team of specialized AI reviewers checks every sheet — grading, drainage, code, coordination, the small stuff — pins each issue to the drawing, and hands you a report you can stand behind. You stay the final word.
Currently onboarding a small group of firms. No demoware — real plans, real findings.
You already know
where the errors hide.
It's sheet 9 of 14, 11 p.m., the deadline's tomorrow. The grading callout that doesn't match the profile. The detail that references a sheet that got renumbered three revisions ago. The inlet the lot slopes away from.
None of it is hard to catch. It's just hard to catch everything — on every sheet, every time — after six hours in the set. Manual QA is 4–8 hours you don't have, and the one thing you miss is the one that comes back as a field RFI.
What if every set got a full, consistent review — in minutes?
Not a spell-checker. A review that understands grading, drainage, accessibility, standards, and cross-sheet coordination — and tells you exactly where to look and why.
How it reviews your plans
Enough to trust it. We'll keep the rest to ourselves.
It reads the actual drawings
Not the text layer, not metadata — a vision model that sees the linework, the callouts, and the elevations the way a reviewer does.
A team of specialists, not one generalist
Separate reviewers for grading & drainage, standards & code, quality, and cross-sheet coordination — the way a real firm splits a review. Each one is sharp at its discipline.
It always checks its own work
Before a single finding reaches you, it's been cross-examined and reconciled — so what you get is signal, not a wall of false positives.
Everything is traceable
Every finding is pinned to a sheet, a location, and — where it applies — a code reference and a confidence level. Nothing magical. Nothing you can't verify.
What a finding looks like
No black box. Here's the detail you get on every issue — and the call is always yours.
It drafts; you decide. You approve, edit, or reject each one.
An error caught in review is cheap. The same error in the field isn't.
A missed slope, a setback that doesn't meet code, a detail that conflicts with the utility plan — caught in QA, it's a five-minute fix. Caught in construction, it's an RFI, a change order, a delay, and a conversation with the client you'd rather not have.
CivilPlanAI exists to keep errors on this side of the bid set.
You're still the engineer of record.
CivilPlanAI doesn't stamp anything and it doesn't overrule you. It surfaces issues, shows its reasoning, and lets you decide what's real — the most thorough junior reviewer you've ever had, one that never gets tired, never skips a sheet, and holds the same line on set #1 and set #100.
Traceable by design
Sheet, location, code reference, confidence — every finding shows its work.
You approve every finding
Nothing is acted on until you say so. It drafts; you decide.
Your plans stay yours
We don't train on your data, and we don't share it. Your plans are yours.
Built for the people who actually run the review.
Hours back, bar held
Get hours back without lowering the bar on QA.
One standard, every project
One review standard across every project and every reviewer.
A process you can sign
A defensible, consistent quality process you can put your name behind. Reviewing a subconsultant's set? Know what you're stamping.
We're working with a handful of firms first.
CivilPlanAI is being shaped right now, alongside a small group of civil teams who care about getting plan review right. If that's your firm, we'd like to hear from you — what you review, where it hurts, and what good looks like to you. No pitch deck. A real conversation.
Let's talk about your plan sets.
Tell us about the reviews that keep you up at night.
