Firmus vs Marapone SpecChecker

Two pre-bid document checks that look at different documents, so this is only partly like-for-like. Firmus reviews the drawing set itself with computer vision for scope gaps, missing information and discrepancies, and compares sets between phases; Marapone SpecChecker checks the spec book against the drawings with rules and uses a model only to explain what it finds. Desk research from vendor sites read Oct 31, 2026; no winner.

What it doesAI design review for preconstruction that uses computer vision on PDF drawing sets to find incomplete design, scope gaps, missing information and discrepancies across hundreds of sheets, with a dashboard to filter, assign and track issues. Firmus's site says it is now part of Bluebeam (the footer says Bluebeam is part of the Nemetschek Group). Products: AI-REVIEW (computer-vision drawing review; included checks cover architectural packages, MEP connection points and document health such as sheets missing from the set), AI-MATCH (View-to-View Match on all annual plans, Full Set-to-Set Match as a Premium option) and a Procore integration whose RFI Connector groups issues into an RFI that opens in Procore. Analysis is iterative across design stages (100% DD, 50% CD, 90% CD, IFP, IFC). Vendor says it complements, not replaces, human review. Logo wall and case-study claims are not used.Compares project manuals with drawings and addenda and reports conflicts; one of eight programs in Marapone's browser-based construction AI suite (alongside Blueprint Auditor, AI Estimator, ScopeGuard, Bid Leveler and others). SpecChecker reads the project manual, drawing sets, addenda and scanned PDFs (PDF, Word, Excel or scans, with Marapone's own OCR), works out which file is the manual and which are drawings, and reports every place they disagree. Outputs the vendor lists: a dashboard of which packages are safe to order and which to hold, a conflict matrix (spec value and clause, drawing value and sheet, severity, recommended action), a coverage view of which sections and sheets were actually compared, and drafted RFIs, one per section, quoting both documents. Vendor counts 11 conflict types, 27 measurable properties, 39 named assemblies and 25 CSI divisions with 47 sections mapped. Caveats on the vendor's own page: conflicts come from rules and the model only explains them ("the model never finds"); it compares properties as written, not measured off line work; it does not decide which document governs; and findings marked as noise stay suppressed. Vendor says files are processed on Marapone's own infrastructure by its own model, with no third-party AI vendor in the path and nothing uploaded used for training. A mobile app is listed for Q4 2026.
Who it's forGeneral contractors, construction managers, architects, and owners/developers in preconstruction.General contractors, estimators and buyers checking the spec book against the drawings before ordering material or bidding (vendor framing).
Pricing (as publicly stated)No public prices. The pricing page ("Firmus Plan Options", annual subscription plans) lists Basic (5 analyses/year) and Advanced (20 analyses/year), both with Standard SLA and self-service AI-MATCH; Premium (100 analyses/year; adds an enterprise SLA, AI-MATCH Premium full set-to-set drawing comparison, white-label reporting and SSO/enterprise controls); and Enterprise (customized). All include unlimited users and unlimited exports; each has a Get Started button and no figures. Confirm pricing with the vendor.Prices are in CAD per month, flat per firm, pre-tax, vendor-published. SpecChecker is on Crew ($299, up to 3 seats; also opens Blueprint Auditor, AI Estimator and ScopeGuard), Pro ($499, up to 5 seats, all eight programs; extra seats +$59/month) and Firm ($1,199, up to 20 seats; extra seats +$39/month). Yearly: $2,990 / $4,990 / $11,990 first year, renewing at $3,289 / $5,489 / $13,189. Solo ($69) and Field ($149) do not include SpecChecker, and their free trials (7 days Solo, 14 days Field; confirmed email, no card, up to 3 projects) do not open it. New monthly accounts get 10% off the first month. No per-project fees or usage caps per vendor. One-time Custom Workflow builds from $4,900 CAD and Enterprise Integration from $15,000 CAD plus a plan are listed separately. Flag: the SpecChecker page says wiring into Procore, Sage or your own project database is a custom setup from $1,500, which conflicts with the pricing page; confirm with the vendor.

Where the vendor descriptions differ

  • Not like-for-like: Firmus's main input is the PDF drawing set and its findings are about the drawings (incomplete design, scope gaps, missing information, discrepancies). SpecChecker's main job is spec-versus-drawing conflicts, so it needs both the project manual and the drawings. A team that wants both kinds of check may need two tools or one that covers both.
  • How issues are found (vendor statements): Firmus says its computer-vision AI scans hundreds of drawing sheets in AI-REVIEW, and AI-MATCH compares drawing sets between project phases to find variances and changes. Marapone says SpecChecker's rules find the conflicts and the model only explains them, and that it does not decide which document governs.
  • Across the design phases: Firmus says its analysis is iterative, so drawings can be re-uploaded at 100% DD, 50% CD, 90% CD, IFP and IFC to track resolved issues and catch new ones, with a dashboard to filter, assign and track issues. Marapone sells SpecChecker inside a suite with other document and estimating tools on its Crew plan and above.
  • Ownership and data (vendor statements): Firmus's homepage says it is now part of Bluebeam, which is part of the Nemetschek Group, and lists a Procore integration. Marapone says it runs an open-weights model on its own infrastructure with no third-party AI vendor and no training on customer files.
  • AI (our reading): both are AI-first products. Firmus applies AI to the drawings themselves; SpecChecker puts rules first and uses AI for explanations.
  • Pricing (checked Oct 31, 2026): Firmus publishes annual plans by number of analyses (Basic 5, Advanced 20, Premium 100 a year, Enterprise customized) with unlimited users, but no dollar figures; full set-to-set AI-MATCH is a Premium option. Marapone lists flat per-firm monthly plans in CAD, with SpecChecker opening on Crew at $299 (up to 3 seats), then Pro $499 and Firm $1,199. Its SpecChecker page lists custom setup from $1,500 while its pricing page lists Enterprise Integration from $15,000 CAD; confirm with the vendor.

Good or bad, an honest review from an estimator, PM or super helps the next team more than another vendor demo. You post under a handle; your email is never shown.

Questions to ask in your review

  • Whether your bigger problem is gaps within the drawings or conflicts between the specs and the drawings
  • Real issues versus false alarms from each on the same project documents
  • What a Firmus analysis costs and how many you would use in a year
  • What did you use it for, on what kind of work and project size?
  • How long did setup and training take, and who on your team did it?
  • What does it cost you in practice, compared with what the sales call said?
