Neuron Factory vs Trunk Tools

Two AI platforms that both describe a construction knowledge graph built from every project document, pointed at different stages of the job. Neuron Factory calls itself an AI-native preconstruction platform with four modules (Bid Graph, Takeoff Graph, Conflict Graph and Project Graph) for tender risk, takeoff, spec-versus-drawing conflicts and subcontractor bid packages. Trunk Tools reads project documents into Cortex, its knowledge graph, and runs tools for RFIs, submittals, bulletins, bids, change events and SMS questions for U.S. site teams. Neither publishes prices. Desk research from vendor pages read Oct 29, 2026; not tested, no winner.

What it doesAI-native preconstruction platform on a construction knowledge graph that captures documents, decisions and version changes to surface risks. Re-read Oct 17, 2026: four modules, Bid Graph (tender package risk review, project overviews, clause annotation), Takeoff Graph (computer vision drawing classification, quantity and object takeoff, 2D-to-3D views), Conflict Graph (spec-versus-drawing and cross-discipline conflicts ranked by severity, with a revision audit trail) and Project Graph (trade bid packages mapped to your templates, editable Word scopes of work). It says answers cite source sheets and leave fields blank when confidence is low. SOC 2 Type 1 announced Oct 15, 2026 (vendor statement). Re-checked Oct 19, 2026: platform pages unchanged in substance; the homepage says it field-tests its models with general contractors in North America, Europe and the Middle East, and the security page lists SSO and MFA for internal access, TLS 1.2 or higher in transit, AES-256 at rest and a SOC 2 report available under NDA. The Project Graph page also says its AI compares incoming sub quotes on pricing, coverage, exclusions and terms into leveled estimates, and the Technology page describes 50+ specialized agents, multilingual reading and output, and inheriting each user's access controls on top of existing systems. Note: the homepage footer says SOC 2 Type I Certified, but the security page still says SOC 2 Type I attestation is in progress, so confirm status with the vendor. Homepage performance figures (bid speed, RFI cost, conflict detection) are vendor claims and not used here. Re-checked Oct 21, 2026: homepage unchanged in substance (Bid Graph, Takeoff Graph, Conflict Graph and Project Graph; field-testing with general contractors in North America, Europe and the Middle East); the footer still says SOC 2 Type I Certified. Its bid-speed, RFI-cost and conflict-detection figures are vendor claims not used here. Re-checked Oct 23, 2026: homepage unchanged in substance (Bid Graph, Takeoff Graph, Conflict Graph and Project Graph; tender package review, drawing classification and quantity takeoff, 2D-to-3D views, conflict detection prioritized by severity, trade bid packages and one-click Word scopes of work); the footer now links a Trust Center, and the security page still describes the SOC 2 Type I attestation as in progress while the footer says SOC 2 Type I certified. Re-checked Oct 26, 2026: homepage unchanged in substance (Bid Graph, Takeoff Graph, Conflict Graph and Project Graph; field-testing with general contractors in North America, Europe and the Middle East). The footer and security page still say SOC 2 Type I Certified while the security page body still says the SOC 2 Type I attestation is in progress, so confirm status with the vendor. Homepage bid-speed, RFI-cost and conflict-detection figures are vendor claims not used here. Re-checked Oct 29, 2026: the homepage footer still says SOC 2 Type I Certified and links a Trust Center, while the security page still says the SOC 2 Type I attestation is in progress. Both statements are on the vendor's own pages, so confirm current status with the vendor.AI platform that reads project documents and drawings into a knowledge graph and runs tools for bids, RFIs, submittals, bulletins and SMS Q&A. The platform ("Cortex") plugs into a project's tech stack, reads documents and drawings into a living knowledge graph, and runs tools on top: TrunkBid (maps subcontractor bids against scope and highlights gaps), TrunkRFI (catches RFIs documents already answer and drafts the rest), TrunkRegister (reads a spec book and builds the submittal register), TrunkSubmittal (reviews submittals against the specs and drafts responses), TrunkReview (highlights clouded and unclouded changes from new bulletins), and TrunkText (SMS Q&A with source checks). Vendor says custom AI models are trained on 5+ years of jobsite data, live on 1,000 U.S. projects handling $50B in construction volume, and that teams get in-person jobsite training plus head-office change management (vendor claims). Re-checked Oct 19, 2026: (rendered in headless Chrome) the tool list now adds TrunkBrowse, which identifies and classifies objects on each sheet and links each one to its schedule row, spec section, RFIs, submittals and other sheets, and TrunkChange, which detects a change event when a bulletin or RFI response lands, traces affected trades and drafts the change event and potential change order with a rough-order-of-magnitude estimate by discipline, writing them back to the system of record. TrunkText now answers by text, web or Teams. Headline figures (1,000 U.S. projects, $50B volume) are unchanged vendor claims; the TrunkBrowse page's door-detection comparison against a generic AI model is a vendor claim, not verified. Re-checked Oct 21, 2026: homepage unchanged in substance (Cortex knowledge graph across project documents and drawings, with tools including TrunkText, TrunkSubmittal, TrunkRFI, TrunkReview, TrunkBid, TrunkBrowse, TrunkChange and TrunkRegister; the 1,000-project and $50B figures are unchanged vendor claims). A banner says it is at Groundbreak this week. Re-checked Oct 22, 2026: unchanged in substance; Cortex plus TrunkText, TrunkRFI, TrunkSubmittal, TrunkRegister, TrunkReview, TrunkBid, TrunkBrowse and TrunkChange are still listed, and the Groundbreak banner is still up. Re-read Oct 23, 2026 for a compare: the TrunkBrowse page says it is in beta with general availability in Q4 2026 and recognizes around 400 construction-specific object types; the TrunkChange page says it is planned to launch in Q4 2026; TrunkSubmittal lists Procore and Autodesk integrations plus support for SharePoint, Egnyte, Box or Dropbox, and TrunkRegister pushes to Autodesk via API or exports a Procore-ready CSV.

Where the vendor descriptions differ

  • Knowledge graph: Neuron Factory says it captures every document, decision and version change as a continuous context layer from the first phone call to production handoff. Trunk Tools says Cortex plugs into the tech stack, reads every document and drawing on the project and maps the connections into a knowledge graph that evolves as the project progresses.
  • Where each one sits: Neuron Factory's pages are written for executives, precon leaders, estimators, bid managers, project managers and legal and risk teams before the bid. Trunk Tools' homepage is written for superintendents, project managers, project engineers, project executives, subcontractors and owners during delivery.
  • Tools: Neuron Factory lists Bid Graph (reads tender packages and flags pricing, terms and compliance risks, with collaborative annotation and hyperlinked source summaries), Takeoff Graph (computer vision that classifies drawings, builds a spatial building graph for quantity takeoffs and converts 2D drawings to 3D views), Conflict Graph (spec-versus-drawing and cross-discipline conflicts ranked by severity with an audit trail) and Project Graph (division-by-division subcontractor bid packages exported as editable Word scopes). Trunk Tools lists TrunkText (SMS answers with sources), TrunkSubmittal, TrunkRegister, TrunkReview (bulletin changes), TrunkRFI, TrunkBid (subcontractor bids against scope), TrunkBrowse (sheet objects) and TrunkChange (change events).
  • Overlap: both describe catching scope gaps in subcontractor bids and conflicts that would otherwise come back as RFIs or failed submittals. Takeoff is listed only by Neuron Factory; submittal review, SMS questions and change-event tools only by Trunk Tools.
  • Security: Neuron Factory's footer says SOC 2 Type I certified while its security page says SOC 2 Type I attestation is in progress, so ask for the report; it states TLS 1.2 or higher and AES-256 at rest. Trunk Tools' footer shows SOC 2 Type II (vendor statements).
  • Pricing (checked Oct 29, 2026): neither vendor publishes prices. Neuron Factory has no pricing page (/pricing returns a not-found page) and routes buyers to Get a Demo. Trunk Tools' Core and Enterprise plans are each priced on construction volume with unlimited seats, quoted on request. See each tool page for detail.
  • AI tags: both are listed as AI-first in the directory.
  • Not used here: Neuron Factory's bid-speed, RFI-cost, conflict-detection and margin figures, and Trunk Tools' project count, construction volume, team-weeks and cycle-time figures and customer quotes (vendor material). Neither tool has been tested by Means & Methods Lab.
