Groundbook AI vs Nomic for drawing review
One reviews a set against the standards your firm writes. The other reviews the set against everything it has to agree with. Compared on inputs, checks, outputs, integrations, and pricing from each vendor's site.
Short answer: Nomic's drawing review agent checks every sheet of a set against a firm's own QA/QC standards, which it can also generate from past markups and RFI logs, and it compares revisions to show what changed. Groundbook AI checks the set against the documents it must agree with on this project: other sheets, specifications, reports, your checklists, and the building codes and local ordinances that govern, with each finding linked to its sources. If your firm has written standards to enforce across every project, Nomic is built around that. If the question is whether this set is coordinated, complete, and compliant, that is what Groundbook AI was built for. Nomic starts free with a $20 per month individual tier; Groundbook AI is free to start and pay as you go from $100 per project.
Side by side
Where the two tools differ
| Criterion | Nomic | Groundbook AI |
|---|---|---|
| Built for | Drawing review against firm-specific QA/QC standards, plus revision comparison | Full-set QA/QC: coordination, constructability, consistency, checklist conformance, and code compliance in one review |
| What it checks against | Your written standards, or standards Nomic generates from past markups and RFI logs | Other sheets, specifications, reports, calculations, your checklists, and building codes detected from the drawings, from Groundbook's code library, or from codebooks you upload |
| Inputs | Drawing sets from Autodesk Forma, Bentley ProjectWise, SharePoint, Egnyte, or PDF upload | Drawings, specifications, reports, checklists, and code PDFs; native, scanned, photographed, or hand-drawn sheets; any number of pages |
| Output | Cited findings linked to drawing locations; Bluebeam-ready PDF markups; Excel and JSON exports; native issues in Forma, Fieldwire, and ProjectWise | Findings with severity, discipline, impact, and recommended action, linked to the exact file, page, drawing location, and supporting sources |
| Integrations | Autodesk, Bentley, SharePoint, and more on the Business tier and above; Fieldwire issues | Web app or email upload; import from Autodesk Construction Cloud (Forma), SharePoint/OneDrive, Google Drive, Box, and Dropbox; Procore, Bluebeam, and Egnyte in progress |
| Published pricing | Free tier with limited agent requests; Individual $20 per month; Business $40 per user per month with a 25-seat minimum (file integrations start here); Enterprise custom | Free to start; pay as you go from $100 per project, $1 per drawing page and $0.25 per reference page; exact price shown before payment; no per-user fees |
| Turnaround | Not stated; positioned as review during design or at ingestion | Typically 20 minutes to 24 hours, depending on project size |
| Data hosting | Multi-region hosting (EU, AU, US, UK) on Enterprise; org-wide privacy controls on Business | Customer data hosted on AWS in the United States, encrypted at rest and in transit; model providers contractually prohibited from training on customer project data |
| Professional judgment | Findings for the firm's reviewers to act on | Stays with your team. Groundbook AI assists review and does not replace architects, engineers, contractors, owners, or code officials |
Right tool, right job
When Nomic is the right tool
Nomic is strongest where a firm already has standards worth enforcing:
- A written QA/QC standard, or a backlog of markups and RFI logs that Nomic can turn into one
- Sets that live in Forma, ProjectWise, SharePoint, or Egnyte and a team on the Business tier that wants findings pushed back as native issues
- A workflow that ends in Bluebeam markups, Excel, or JSON
- Revision-to-revision comparison as a routine step
The free tier and the $20 individual tier make it easy for one person to try.

When you need Groundbook AI
Most costly drawing problems are not violations of a firm standard. They are two documents describing the same building differently. Reach for Groundbook AI when:
- The set has to agree with specifications, geotechnical or other reports, and calculations, not only with itself
- Code compliance is in scope: Groundbook AI detects the applicable codes from the drawings, checks against its code library, and lets you upload your own codebooks, local ordinances, or a public code link
- Part of the set is scanned, photographed, or hand-drawn; see how scanned sets are reviewed
- You want to pay per project rather than per seat, with the exact price shown before payment
- You need a published security statement for the client's review

Frequently asked questions
Is Groundbook AI a Nomic alternative?
For drawing review, yes. Nomic checks sets against a firm's own QA/QC standards and compares revisions. Groundbook AI checks the set against specifications, reports, checklists, and building codes as well as against itself, and returns findings linked to their sources. Some firms could use both: Nomic to enforce house standards, Groundbook AI for the project-specific review.
Which is cheaper?
For one person, Nomic: it has a free tier and a $20 per month individual plan. For a team that needs file integrations, Nomic's Business tier is $40 per user per month with a 25-seat minimum. Groundbook AI charges per project from $100, $1 per drawing page and $0.25 per reference page, with no per-user fees and the exact price shown before payment.
Does Nomic check building codes?
Nomic's published material describes review against firm-defined standards and cross-sheet consistency, not against code sources. Groundbook AI detects the applicable codes from the drawings, checks against its code library, and lets you upload your own codebooks, local ordinances, or a public code link.
Which tools accept scanned drawings?
Groundbook AI reads every sheet as an image and treats any OCR layer as a draft corrected against the print. Nomic's published material describes PDF and platform inputs without addressing scans.
