Trunk Tools Review 2026: Construction-Native Document AI Agents
Updated October 13, 2026 – Tested Intelligence
Quick verdict: Trunk Tools builds AI agents specifically for construction documents: ask questions across drawings, specs and submittals and get cited answers; run submittal review and contract review as agent workflows; coordinate drawings with TrunkCoordinate (September 2026); and level bids with TrunkBid (beta, March 2026). ENR-reported adopters include Gilbane, and Cleveland Construction piloted then expanded its use – the adoption pattern you want to see. Pricing is not public.
What it is
Every construction AI category has a data problem, and documents are the worst of it: drawings, specs, submittals and contracts scattered across systems, with answers needed in minutes during meetings and RFIs. Trunk Tools is built construction-native for exactly that corpus – its Q&A works across drawings, specifications and submittals and returns answers with citations, so a project engineer can verify the source instead of trusting a chatbot.
The product has grown from Q&A into agents that do document work: a submittal-review agent, a contract-review agent, TrunkCoordinate for drawing coordination (launched September 2026), and TrunkBid, a bid-levelling agent that entered beta in March 2026. The adoption signal in trade coverage is credible: ENR reported Gilbane among its users, and Cleveland Construction’s pilot-then-expand path is how serious GCs actually buy. One caution: the contract-review agent was reported as a free tool in early 2026, so verify current terms – what is free, what is platform – before planning around it.
Key features
- Cited Q&A across drawings, specs and submittals – answers traceable to source documents
- Submittal-review agent workflow
- Contract-review agent (reported as a free tool in early 2026 – verify current terms)
- TrunkCoordinate for drawing coordination (September 2026)
- TrunkBid bid-levelling agent (beta, March 2026)
- ENR-reported adopters include Gilbane; Cleveland Construction piloted then expanded
Pricing
Trunk Tools does not publish pricing – expect a demo-led, quote-based process sized to the firm or project portfolio. One nuance worth asking about directly: the contract-review agent was reported as a free tool in early 2026. Whether that remains the case, and which agents sit in which paid tier, should be pinned down in the first sales conversation.
Who it’s for
GC and subcontractor project engineers and PMs whose days are consumed by document questions – what does the spec say, has this been submitted, what changed in this drawing set – and firms standardising submittal and contract review across projects.
Who should skip it
Firms whose documents live in chaos with no consistent project filing: cited Q&A needs a findable corpus. Also skip if you only need contract risk review as a standalone – Document Crunch is the dedicated specialist there.
Pros
- Built for construction documents specifically, with cited answers
- Agent set now spans Q&A, submittals, contracts, coordination and bid levelling
- Credible adoption: ENR-reported Gilbane use; Cleveland Construction expanded after pilot
- New capabilities shipping in 2026 (TrunkCoordinate, TrunkBid) show momentum
Cons
- No public pricing – quote-based only
- TrunkBid is beta (March 2026) – treat levelling output with extra care
- Free-tool status of the contract agent (early 2026 reports) needs re-verification
- Answers are only as good as the document set you feed it
