Helonic vs Structured AI

Two AI-first tools that check design documents before they reach the field, with different centers. Helonic reads the full project manual alongside the drawing set and flags conflicts between them, with cited findings and severity ratings. Structured AI is a drawing review platform for architects and engineers that runs QA/QC and code checks across sheets, disciplines and revisions, and works inside Revit, AutoCAD and Civil 3D. Both are sold by demo or quote. Desk research from vendor sites read Nov 4, 2026; no winner.

What it doesAI 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 CSI MasterFormat 2020 (Divisions 00-49), the older 16-division MasterFormat 1995 and SectionFormat 3-part specs (including master, proprietary, performance and descriptive specs and MasterSpec and SpecLink-based books) against the drawings and flags 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 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. The FAQ says the AI flags candidate issues and the spec writer decides, and describes the AI as strongest on quantitative cross-references and weakest on intent. Vendor says it is backed by Y Combinator. 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. Accuracy, volume and savings figures are not used.AI drawing review for architects and engineers that flags errors, code issues and clashes across sheets, disciplines and revisions. It lists QA/QC and code compliance checks with deterministic pass, fail or verify results cited to sheet and location, drawing set chat with sourced answers, custom checks in plain English, pixel-aligned sheet and discipline overlays for clash checks, and an agent that explains a finding, its root cause and other places it appears. A Revit add-in runs checks on live model elements and writes approved fixes back; the menu also lists an AutoCAD and Civil 3D add-in and IFC and RVT models viewed in 3D in the browser and queried through chat. Findings arrive as Bluebeam markups with two-way Studio sync. Integrations: Revit, Autodesk Construction Cloud, Procore, Bluebeam, SharePoint, OneDrive, Google Drive, Egnyte (linked folders kept in sync), Microsoft Outlook and Gmail (transmittals, RFI responses and attachments reconciled against the set), Microsoft Word (specifications) and Microsoft Excel (door schedules, equipment registers and takeoff sheets cross-checked against the drawings), Microsoft Teams (channels and chats checked against the set, with replies posted only on approval) and an MCP connector for AI apps such as Claude and ChatGPT. Security page (vendor statements): the platform is model-agnostic and uses AI partners under zero data retention terms, and neither Structured AI nor its AI partners train on project data; data is logically separated by organization and the AI acts with each user's own permissions; it runs on Microsoft Azure in the US by default, or in a chosen Azure region or the customer's own Azure tenant; it lists SOC 2 Type 2 audits (report under NDA), a GDPR and UK GDPR data processing addendum, CCPA/CPRA and Microsoft Entra ID single sign-on. The buying path is an intro call and live demo, then a pilot on the buyer's own drawing sets. Funding news and review-time, confirmation-rate and field-issue figures are vendor material and are not used.

Pricing (as publicly stated)Not publicly listed. Starter (multi-discipline analysis, code compliance checks), Professional (unlimited sheets, Procore integration pushing issues as RFIs, custom checklists, team collaboration) and Enterprise (SSO/SAML, custom integrations, on-premise deployment, SLA guarantees) are all listed as Custom (contact sales), priced on project volume and team size. Pilots for qualified teams; annual-commitment discounts. No dollar figures.No public prices: getstructured.ai/pricing redirects to the contact page (Book a Demo), and the homepage menu and footer do not link to pricing. A pricing page with seat and per-run prices was published briefly on Oct 29, 2026 and then withdrawn, so those figures are not shown here; ask the vendor for current pricing.

Where the vendor descriptions differ

  • Partly like-for-like (our reading): both look for errors in a design set before construction. Helonic is built around the spec book versus the drawings; Structured AI is built around the drawing set and the model, with specifications (through Microsoft Word) among several companion documents it can check against.
  • What each checks (vendor statements): Helonic lists material, finish and hardware schedule mismatches, equipment versus performance specs, items specified but not drawn and drawn but not specified, fire-rating and acoustic mismatches, references to sections or standards that do not exist, Division 01 requirements and incomplete submittal requirements, across MasterFormat 2020, MasterFormat 1995 and SectionFormat specs. Structured AI lists QA/QC and code compliance checks, custom checks in plain English, pixel-aligned sheet and discipline overlays for clash checks, drawing set chat with sourced answers and revision comparison.
  • How findings come back: Helonic cites the spec section and sheet for each finding with a low, medium or high severity and page coordinates. Structured AI cites each finding to the sheet and location with a pass, fail or verify result, which it describes as deterministic rather than a confidence percentage, and an agent explains the root cause and other places the issue appears.
  • Where they connect (vendor statements): Helonic pulls drawings from Procore or Autodesk Construction Cloud and pushes issues back as RFIs (Procore integration on the Professional tier). Structured AI lists Revit, Autodesk Construction Cloud, Procore, Bluebeam (two-way Studio markup sync), SharePoint, Google Drive, Outlook, Gmail, Word and Excel, and a Revit add-in that writes approved fixes back to the model.
  • Who decides: Helonic's FAQ says the AI flags candidate issues and the spec writer decides, and that it is strongest on quantitative cross-references and weakest on intent. Structured AI says nothing runs in the model until a user approves it and that findings are cited for verification.
  • Who each names: Helonic names spec writers, owner's reps, preconstruction estimators and plan reviewers, with GCs and engineering firms on the Professional tier. Structured AI names architects and engineers.
  • Security (vendor statements): Helonic says it is SOC 2 compliant and deletes files within 7 days of project closure. Structured AI lists SOC 2 Type 2 audits (report under NDA), GDPR and CCPA terms, Azure hosting by region or in the customer's own tenant, and no training on project data by it or its AI partners.
  • Pricing (read Nov 4, 2026): neither publishes dollar figures. Helonic lists Starter, Professional and Enterprise tiers, all Custom and priced on project volume and team size, with pilots for qualified teams. Structured AI routes pricing to Book a Demo and offers a review on a live project. See each tool page for detail.
  • Not used here: Helonic's accuracy, volume and savings figures, and Structured AI's funding news and review-time, confirmation-rate and field-issue figures (vendor material). Facts for both tools come from vendor websites (desk research).

Good or bad, an honest review from an estimator, PM or super helps the next team more than another vendor demo. You post under a handle; your email is never shown.

Questions to ask in your review

  • Whether your main gap is spec-versus-drawing conflicts or sheet-to-sheet, code and model QA/QC
  • Real issues versus false flags from each on the same project manual and drawing set
  • What either costs for your project volume
  • 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?
