SpecChecker

Two contract documents. One of them is wrong. SpecChecker — specification compliance software that checks the project manual against the drawings

The drawing says 1/2-inch drywall. Section 09 29 00 requires 5/8-inch Type X. SpecChecker finds every place the manual and the drawings disagree, before the material is ordered.

Before you start

Questions about SpecChecker.

Which plan opens SpecChecker?

Crew and up. Crew is $299 a month for up to three people and also opens Blueprint Auditor, the AI Estimator and ScopeGuard; Pro ($499) and Firm ($1,199) open all eight programs. The five plans.

Is there a free trial?

The free trials are on Solo (seven days) and Field (fourteen), and neither opens SpecChecker. To see it on your own documents first, send us one manual and drawing set and we will walk you through what it finds.

Does it decide which document governs?

No. Which document governs is a question for the consultant of record. SpecChecker finds the disagreement, quotes both sides with their references, and drafts the RFI that asks — while the answer is still free.

What files does it read?

PDF, Word, Excel or a scan. It works out which file is the manual and which are drawings from section numbers, PART blocks, sheet numbers and title blocks, shows its guess on screen, and lets you override it.

Where do my documents go?

To a workspace scoped to your account, on Marapone’s own infrastructure, read by our own model. No third-party AI vendor is in the path and nothing you upload trains any model. Cancel from your dashboard with no notice period, and your work exports to PDF, Excel and CSV.

SpecChecker reports where two contract documents disagree. It does not decide which one governs, and it does not replace a design review, a code review or professional judgement.
