Helonic is a Y Combinator-backed AI construction drawing analysis company in San Francisco. It reviews issued 2D PDF sets and returns issues with sheet locations. Nomic is an AI agent platform for AEC firms that covers drawing review, submittals, project search, and an API.
Both review drawings now. The split is scope: one review job done the same way on every set, or one AI workspace for everything the firm knows.
Nomic facts below come from nomic.ai, its pricing page, and its integrations page, checked October 2026.

Yes, Nomic now ships a Drawing Review agent, so this is a closer comparison than it was a year ago. Nomic's agent checks a drawing set against your firm's QA/QC standards and 380+ codes, returns cited PDF markups, and can send findings to Autodesk Forma, Fieldwire, or Bentley ProjectWise as issues. Older write-ups that call Nomic a developer-only API are out of date.
Nomic is built as a firm-wide AI workspace. Drawing review sits next to submittal review, RFI research, report drafting, detail search across past projects, and IFC model queries. Its public customer story is Arcadis, and its pitch is aimed at the engineers and designers inside AEC firms. Pricing is per seat, from a free tier up to $40 per user per month on Business with a 25-seat minimum.
Helonic does one job: review the issued set. Every sheet is checked across 10 categories (coordination, code compliance, missing information, structural, MEP, fire safety, accessibility, constructability, dimensions, and QA/QC), and each finding carries a severity and a sheet location. It also cross-references specs against drawings, compares revisions, and checks door, window, and finish schedules. Findings go into Procore or Autodesk Forma as RFIs in one click.
Neither tool replaces the other everywhere. Helonic does not search a firm's past projects, query IFC models, or check BIM models. Nomic does not list a Procore connector, which matters for general contractors whose RFI log lives there. If you are weighing several review tools, the 2026 ranking of AI drawing review tools and the Nomic alternatives list cover the wider field.
Milind is the co-founder and CEO of Helonic, where he leads product and go-to-market for AI-powered construction drawing analysis. He works closely with general contractors, project managers, estimators, and owners to understand how drawing quality drives project outcomes - and where AI can reduce RFIs, change orders, and rework. Milind has interviewed hundreds of construction professionals across project delivery roles, from preconstruction estimators at ENR top-400 contractors to facilities directors at institutional owners, and uses those conversations to shape both product direction and the way Helonic talks about the work.
