Nomic vs Archidian
Last reviewed: May 2026
Both platforms check construction drawings against building codes. Archidian is purpose-built for jurisdictions and permit intake. Nomic covers code compliance as part of a broader AEC document intelligence platform. Here's how to choose.
Choose Nomic if…
Firms that need code compliance as part of a broader document intelligence workflow — alongside submittal review, drawing search, spec queries, and RFI processing.
Choose Archidian if…
Architecture firms and building departments that primarily need fast, automated code compliance checking focused on permit intake and plan review.
Key tradeoff
Archidian is focused on code compliance and plan review. Nomic covers code compliance within a full-stack AEC AI platform. If code compliance is your primary workflow, Archidian may deploy faster. If you need code compliance plus the rest of your document stack, Nomic covers more ground.
Feature comparison
How they compare
| Feature | Nomic | Archidian |
|---|---|---|
| Building code compliance checking | 380+ codes — architectural, structural, MEP, fire | IBC, ADA, NFPA, CBC — deep per-check analysis |
| Drawing-level code analysis (not just document text) | Full — dimensions, egress, occupancy from drawings | Full — analyzes 2D PDF drawing sets |
| Permit intake screening (sheet index, title blocks, signatures) | Not available | Native — built for jurisdiction workflows |
| Local code amendments and municipal packages | State and major municipal codes covered | Upload custom local code packages |
| Automated submittal review | Full workflow | |
| Project-wide search (drawings + specs + submittals) | ||
| Cited code findings with section references | ||
| Procore / ACC integration | Limited | |
| Developer API | Full Drawing Parse API + REST | |
| Enterprise on-prem / VPC deployment | ||
| Minimum seat commitment | 25 seats ($1,000/mo min) | Flexible — per-check options available |
Where Nomic wins
- Covers 380+ codes and standards across all disciplines — architectural, structural, mechanical, electrical, plumbing, fire — not just IBC and ADA.
- Code compliance is one capability within a full document intelligence platform: the same tool also handles submittal review, spec search, drawing QA/QC, and RFI cross-referencing.
- Enterprise integrations with Procore, ACC, Bentley, SharePoint, and Egnyte keep project documents in sync automatically.
- Enterprise deployment options — SOC 2 Type II, on-prem, VPC, zero data retention — for firms with strict governance.
- Developer API enables firms to embed drawing intelligence and code checking into custom internal tools.
Where Archidian wins
- Archidian is purpose-built for permit intake: it checks sheet indices, title blocks, and signature requirements that Nomic does not automate.
- Custom local code package uploads allow jurisdictions to add municipal amendments beyond what's in Nomic's standard library.
- Per-check pricing makes Archidian accessible to small firms or consultants who don't need a full platform subscription.
- Faster deployment for code-compliance-only use cases — no broader platform onboarding required.
- Designed for both architecture firms and building departments/jurisdictions — a workflow Nomic does not target.
Choose Nomic if…
- Code compliance is one of several AI workflows you need — you also need submittal review, spec search, or drawing QA/QC
- You need broad code coverage across multiple disciplines: structural, MEP, fire protection alongside architectural codes
- Your team works with complex drawing sets where cross-discipline conflicts matter beyond code compliance alone
- Enterprise security, SOC 2, and on-premise deployment are requirements for your firm
- You want one platform covering the full AEC document stack rather than separate point solutions
Choose Archidian if…
- Code compliance checking is your primary workflow and you don't need broader document intelligence
- You need permit intake screening — checking sheet completeness, signatures, and title blocks
- You need to upload custom local code amendments for specific jurisdictions
- You're a building department or jurisdiction, not an architecture or engineering firm
- Your team is small or you prefer per-check pricing over a platform subscription
Frequently asked questions
Answers to common questions about this comparison.
Nomic covers 380+ building codes, standards, and local amendments across disciplines — IBC, ADA, NFPA, ASCE, energy codes (ASHRAE, Title 24), accessibility standards, and discipline-specific standards for structural, MEP, and fire protection. Archidian focuses primarily on IBC, ADA, NFPA, and California Building Code (CBC), with the ability to upload custom local code packages for municipal amendments.
No — Archidian is focused on building code compliance and plan review. It does not have an automated submittal review workflow. Nomic handles submittal review as a core workflow: extracting product data from submittals, comparing against specification sections, and generating cited deviation reports.
Archidian. It is purpose-built for permit intake and jurisdiction workflows — checking sheet completeness, validating title blocks, and supporting the intake screening process that jurisdictions need. Nomic is designed for architecture and engineering firms, not for government plan review departments.
Accuracy varies by code domain and drawing quality. For IBC life safety, egress calculations, and occupancy-based requirements, modern AI tools including both Nomic and Archidian report high accuracy on clean PDF drawing sets. Both platforms require licensed professional review of AI-generated findings before any code interpretation is relied upon for permit submission or construction.
