Groundbook AI vs Nomic for drawing review
Both offer drawing review and code checks. Compare their review workflow, source evidence, integrations and pricing on the same project, using the current vendor documentation.
Short answer: both tools review drawing sets and return cited findings. Nomic offers drawing QA/QC, code checks and submittal review within a broader AEC agent platform; firm standards are optional for starting a drawing review. Groundbook AI organizes a project review across drawings, specifications, reports, checklists and applicable code sources, with potential findings linked to drawing locations. Choose by the scope, evidence and review process you need, then compare the results on your own documents. Nomic uses subscription plans with AI usage; Groundbook AI has credit plans from $100/month, with pay as you go for extra usage.

Side by side
Where the two tools differ
| Criterion | Nomic | Groundbook AI |
|---|---|---|
| Built for | AEC agents for drawing review, code compliance, submittals and project research | Full-set QA/QC: coordination, constructability, consistency, checklist conformance, and code compliance in one review |
| What it checks against | Built-in discipline checklists, optional firm standards, code sources with Codes Search, and project drawings/specifications for submittals | Other sheets, specifications, reports, calculations, your checklists, and building codes: codes and amendments that governments publish online; licensed model codes (such as the I-Codes, NFPA, and ASME) only where a license allows it |
| Inputs | Drawing sets from Autodesk Forma, Bentley ProjectWise, SharePoint, Egnyte, or PDF upload | Drawings, specifications, reports, checklists, and copies of codes you're licensed to use, where your license allows it; native, scanned, photographed, or hand-drawn sheets; any number of pages |
| Output | Drawing review table with sheet citations, severity and discipline; PDF callouts readable in Bluebeam | Findings with severity, discipline, impact, and recommended action, linked to the exact file, page, drawing location, and supporting sources |
| Integrations | Autodesk, Bentley, SharePoint and other file integrations on Business and Enterprise | Web app or email upload; import from Autodesk Construction Cloud (Forma, including Revit sheets), SharePoint/OneDrive, Google Drive, Box, Dropbox, Egnyte, Bluebeam Studio, Bentley ProjectWise, and Fieldwire; Procore in progress |
| Published pricing | Free with limited requests; Individual $20/month; Business $40/user/month, 25-seat minimum; Enterprise custom. AI usage and top-ups affect total cost | 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 | Findings appear during the review; no universal full-set completion time in the cited drawing-review documentation | 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 barred 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
Consider Nomic when you want a broader AEC agent workspace:
- Drawing review alongside submittal review and project research
- Optional house standards layered onto built-in drawing checks
- A conversational review that can be packaged into a repeatable team workflow

The free and Individual plans provide a starting point. Confirm included AI usage and integration access for your intended workload.
A project review workflow
When to evaluate Groundbook AI
Evaluate Groundbook AI when you want a dedicated project review with evidence your team can verify:
- You need to trace agreement among drawings, specifications, geotechnical or other reports, and calculations
- Code compliance is in scope: Groundbook AI detects the codes the drawings cite, reads the building codes and amendments that governments publish online, and uses licensed model codes (such as the I-Codes, NFPA, and ASME) only where a license allows it
- 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
See what a full-set review surfaced on a mixed-use residential project: most of the 42 potential findings were coordination and consistency issues between disciplines.
These are reasons to test the workflow, not claims that another tool cannot perform the same task. Compare document coverage, citation accuracy, comment handling and the full cost of a representative review.

Frequently asked questions
Is Groundbook AI a Nomic alternative?
Yes, for construction document review. Both offer drawing QA/QC and code checks with cited results. Nomic also positions its platform around broader AEC agent workflows. Evaluate the scope, source evidence and review process on your own documents.
Which is cheaper?
Compare the workload, seats, integration needs and AI usage. Nomic has Free, $20/month Individual, and $40/user/month Business plans with a 25-seat minimum; usage can require top-ups. Groundbook AI charges per project from $100, at $1 per drawing page and $0.25 per reference page, with the exact price shown before payment.
What if I'm not happy with Groundbook AI's results?

Does Nomic check building codes?
Yes. Its current material describes cited code checks in chat, workflows and the API; the drawing-review documentation directs code and accessibility checks through Codes Search. Groundbook AI also checks applicable code sources, using government-published material and licensed references only where permitted. Verify jurisdiction, edition and evidence in either tool.
Do I need firm standards before trying Nomic?
No. Nomic's current drawing-review documentation says a set can be reviewed without a standards document. You can add firm standards or QA/QC checklists to steer the review.
