Nomic vs CONXAI
Last reviewed: September 2026
We built this comparison for teams evaluating agentic AI for construction documents. CONXAI is a no-code agentic AI platform from Germany, with DocNostic for cross-document workflows and SiteLens for jobsite photo and video reporting. Nomic ships ready-to-run review workflows for drawings, specs, submittals, RFIs, and codes, working alongside architects, engineers, contractors, and owners. Here is how they compare as of September 2026.
Choose Nomic if…
Teams that want ready-to-run review of drawings, specs, submittals, and RFIs, plus code compliance against 380+ codes and IFC model Q&A, with citations back to the source sheet or section.
Choose CONXAI if…
Teams that want a configurable, no-code agent platform to build their own document workflows, or that need automated site reporting from jobsite photos and video.
Key tradeoff
CONXAI gives you building blocks to configure workflows and adds jobsite visual analysis. Nomic ships specific AEC review workflows and connectors to document systems, and does not do reality capture or progress tracking.

Where Nomic wins
- Ships specific review workflows out of the box: drawing QA/QC across sheets and disciplines, drawing set comparison, specification version comparison, and submittal review with completeness checklists and comment closure tracking.
- Checks drawings and submittals against 380+ codes and standards, including IBC, ADA, NFPA, and local amendments, with cited sections. Code compliance is not a listed CONXAI workflow.
- Answers questions about IFC models (IFC2x3, IFC4, IFC4x3) and surfaces early clash candidates alongside the drawing and spec review.
- Researches RFIs and drafts responses with citations to the drawings and specs, and drafts RFP responses.
- Connects to Autodesk Construction Cloud, Bentley ProjectWise, Trimble ProjectSight, SharePoint, Egnyte, Fieldwire, Google Drive, Box, Dropbox, Microsoft Teams, Outlook, and Gmail, with data hosting in the US, EU, UK, or Australia.
Where CONXAI wins
- SiteLens analyzes jobsite photos and video to produce reports on site conditions, labor, equipment utilization, and ongoing activities, a category Nomic does not serve.
- Lean construction analytics from site visuals and budget data, including Cascade and Burndown analysis and Line of Balance, to monitor schedule and budget compliance.
- A no-code, configurable platform: teams define DocNostic workflows with natural-language inputs and start with one use case, then expand, instead of adopting a fixed set of workflows.
- Lists both SOC 2 and ISO 27001 certification, which matters for European buyers whose procurement asks for ISO 27001 specifically.
Choose Nomic if…
- You want drawing, spec, and submittal review workflows that run without configuring them yourself
- You need code compliance checks with cited sections as part of QA/QC
- You want to query IFC models alongside the drawing set
- Your documents live in ACC, ProjectWise, ProjectSight, SharePoint, Egnyte, or common cloud storage
Choose CONXAI if…
- You need automated reporting from jobsite photos, video, or drones
- You want lean construction metrics tied to site progress
- You have document workflows specific to your company and want to configure agents for them without custom development
- Your procurement requires ISO 27001 certification
Frequently asked questions
Answers to common questions about this comparison.
CONXAI is a construction AI company based near Munich, Germany (Conxai Technologies GmbH, registered in Karlsfeld). It offers a no-code agentic AI platform with two main modules: DocNostic for extracting and cross-referencing information across specs, drawings, RFPs, and submittals, and SiteLens for analyzing jobsite photos and video.

CONXAI is a configurable, no-code agent platform that also covers jobsite visual reporting through SiteLens. Nomic ships specific AEC review workflows, including drawing QA/QC, submittal review, RFI research, and code compliance against 380+ codes, and connects directly to document systems like ACC, ProjectWise, and SharePoint.
No. Nomic does not do reality capture or progress tracking. Teams that need automated site reports from photos and video should look at SiteLens or another reality capture tool, and can use Nomic for the drawing, spec, and submittal review side.
Code compliance is not a workflow CONXAI lists on its site, which focuses on configurable document workflows and jobsite reporting. Nomic checks drawings and submittals against 380+ codes and standards, including IBC, ADA, NFPA, and local amendments, with cited sections.
