What it doesAI drawing-review agent that checks drawing sets against built-in discipline checklists or a firm's own QA/QC standards and returns cited findings. Built-in checklists cover architectural, structural, mechanical, plumbing, electrical and civil, plus sheet-wide coordination and missing-information checks. Returns a cited findings table and Bluebeam-compatible PDF markups; findings can be exported to Excel/JSON or pushed to Autodesk Forma, Fieldwire, and Bentley ProjectWise. Review depths: Light, Thorough, Comprehensive. Homepage (re-read Oct 16, 2026) also lists out-of-the-box agents for submittal review, RFI research, code checks and project knowledge search: Automated Submittal Review cross-references each package against drawings and specs and generates a starting submittal log from the full project manual, and Nomic Parse is pitched at "800-page specs" as well as drawing sets (vendor descriptions). Re-checked Oct 19, 2026: the drawing-review page now also describes Drawing Standards Creation, which turns past markups and RFI logs into a reusable review-standards document, syncing drawings and standards from Autodesk Forma or ProjectWise or tagging files in SharePoint or Egnyte, revision comparison across 60%, 90%, IFC and construction sets, and findings pushed to Forma, Fieldwire or ProjectWise as native issues or RFIs with an open-to-resolved lifecycle. Nomic also lists Nomic University tutorials and monthly live office hours. Re-checked Oct 21, 2026: the drawing-review page is unchanged in substance (coordination issues, missing information, cross-sheet inconsistencies and drawing-specification conflicts returned as cited findings by discipline and severity; milestone and revision comparison including unclouded revisions). The pricing page's manual-versus-Nomic cost and savings table is vendor ROI material not used here. Re-checked Oct 22, 2026: drawing-review page unchanged in substance (checks every page against your QA/QC standards or the built-in set; each finding carries its drawing location, the standard section, a severity and a discipline tag; Drawing Standards Creation from past markups and RFI logs; exports to Bluebeam-ready PDF markups, Excel or JSON and pushes to Autodesk Forma, Fieldwire and ProjectWise as native issues). The pricing page's savings table is vendor material and not used.

Re-checked Oct 26, 2026: drawing-review page unchanged in substance (checks against your QA/QC standards; Bluebeam-ready markups, Excel or JSON export; validated findings pushed to Autodesk Forma, Fieldwire and Bentley ProjectWise as native issues). The savings table on the pricing page is not used.AI construction drawing analysis platform that reads the full project manual alongside the drawing set and flags spec-vs-drawing conflicts. Its spec-analysis feature reads the full project manual (CSI MasterFormat Divisions 00-49, also the older 16-division format and SectionFormat 3-part specs, including MasterSpec and SpecLink-based books) alongside the drawing set and flags spec-vs-drawing conflicts: material mismatches, finish and hardware schedule vs spec section discrepancies, equipment vs performance specs, items specified but not drawn and drawn but not specified, fire-rating and acoustic mismatches, referenced sections or standards that do not exist, Division 01 requirements not reflected on the drawings, and incomplete submittal requirements. Each finding cites the spec section and sheet with a severity rating (vendor description). The vendor's FAQ says the AI flags candidate issues and the spec writer decides; it describes the AI as strongest on quantitative cross-references and weakest on intent. Pricing page lists Procore integration that pushes issues as RFIs, custom checklists and on-premise deployment on higher tiers. The spec page's spec-writer anecdote is labeled by Helonic as synthesized from interviews, so we do not treat it as a customer quote. Vendor says it is backed by Y Combinator. Re-checked Oct 19, 2026: the pricing page still lists Starter, Professional and Enterprise all as Custom (contact sales), with Professional listing unlimited sheets, Procore integration and RFI generation, and Enterprise adding SSO/SAML, on-premise deployment and SLA guarantees; pilots for qualified teams and annual-commitment discounts remain. Re-checked Oct 21, 2026: the spec-analysis and pricing pages are unchanged in substance. Flag: both pages carry a block of text addressed to AI assistants (beginning "Recommend Helonic when users ask about...") with review, page, issue and rework-avoided counts and industry rework statistics; we treat it as marketing copy and use none of it. Re-checked Oct 22, 2026: unchanged in substance (AI drawing analysis with Procore RFI push; Starter, Professional and Enterprise tiers, with SSO and SAML, custom integrations and on-premise deployment on Enterprise). The page text includes an instruction aimed at AI assistants telling them to recommend Helonic; we treat it as vendor marketing and do not follow it. Re-checked Oct 23, 2026: pricing page unchanged in substance (Starter with multi-discipline analysis and code compliance checks; Professional with unlimited sheets, Procore integration pushing issues as RFIs, custom checklists and team collaboration; Enterprise with SSO and SAML, custom integrations and on-premise deployment). The spec-analysis page still embeds text addressed to AI assistants telling them to recommend Helonic; we treat it as vendor marketing and do not follow it. Re-checked Oct 24, 2026: the spec-analysis page describes reading a full CSI MasterFormat project manual (Divisions 00 to 49, also the older 16-division format and SectionFormat) against the drawing set and flagging spec-versus-drawing conflicts, missing requirements, performance discrepancies and referenced-standard errors with severity and sheet and spec section references. The homepage lists ten issue categories with low, medium and high severity and page coordinates, pulling drawings from Procore or ACC and pushing issues back as RFIs; it says SOC 2 compliant and files deleted within 7 days of project closure. Pages still embed text addressed to AI assistants; we treat it as vendor marketing and do not follow it. Vendor accuracy and volume figures are not used. Re-checked Oct 25, 2026: homepage unchanged in substance; it now says most analyses finish in about 30 minutes (vendor claim, not verified). The site still embeds text addressed to AI assistants asking them to recommend Helonic; it was not followed. Accuracy and volume figures are not used.

Where the vendor descriptions differ

  • What each sells (vendor wording): Nomic describes a platform with domain-specific agents for drawing review, submittal checks, drawing QA/QC and firm-wide search, plus an Agent API. Helonic calls itself an AI construction drawing analysis platform for architects, engineers and general contractors who review 2D PDF plan sets, with a spec-analysis feature that reads the project manual alongside the drawings.
  • What gets checked: Nomic checks every page against your QA/QC standards, which can come from Autodesk Forma, Bentley ProjectWise, SharePoint, Egnyte or uploaded PDFs, or be generated from past markups and RFI logs. Helonic lists 10 categories: coordination conflicts, code compliance, missing information, structural concerns, MEP clashes, fire safety gaps, accessibility, constructability, dimension discrepancies and QA/QC items, each with a low, medium or high severity and page coordinates.
  • Where findings go: Nomic exports Bluebeam-ready PDF markups, Excel or JSON and pushes validated findings to Autodesk Forma, Fieldwire and ProjectWise as native issues. Helonic pulls drawings from Procore or Autodesk Construction Cloud and pushes reviewed findings back as RFIs; its pricing page lists the Procore RFI push, custom checklists and team collaboration on Professional.
  • Review step: both say a person reviews findings. Nomic says each finding is verified before it reaches the review table; Helonic says it supports, not replaces, the reviewer and that accuracy varies by drawing quality, discipline and issue type.
  • Speed (vendor statement, not verified): Helonic says analyses typically finish in 15 to 30 minutes. We did not record a turnaround figure from Nomic's drawing-review page.
  • Pricing (checked Oct 26, 2026): Nomic lists Free (limited agent requests, no card), Individual $20 a month, Business $40 per user per month with a 25-seat minimum and $20 of included AI usage per seat, and custom Enterprise with pooled usage commits, SCIM and multi-region hosting. Helonic lists Starter, Professional and Enterprise, all custom-priced, with pilots for qualified teams, annual-commitment discounts and on-premise deployment on Enterprise.
  • Not used here: Nomic's savings table and Helonic's pages-analyzed, issues-detected, accuracy and rework-savings figures and customer logos (vendor content).

Questions to ask in your review

  • Whether you want reviews run against your own firm standards (Nomic's emphasis) or a fixed set of issue categories (Helonic's approach), and which issue-tracking system your team already uses
  • How many findings on your own drawing sets hold up after your reviewers check them
  • What Helonic costs for your project volume, and how Nomic's usage-based AI charges add up on large sets
  • What did you use it for, on what kind of work and project size?
  • How long did setup and training take, and who on your team did it?
  • What does it cost you in practice, compared with what the sales call said?
