Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Trunk Tools

  • Nothing about pricing is published, and because it is quoted by project rather than by seat, the cost of standardising it across a portfolio of jobs is hard to model before a sales process
  • Answer quality is bounded entirely by the discipline of the underlying document control, and on a project with stale drawing revisions it will cite superseded sheets with the same confidence as current ones
  • It is an overlay on Procore or Autodesk rather than a system of record, so a contractor is now paying two vendors for the same document set and depends on the integration continuing to be maintained
  • The company is young and the product category is new, so there is little independent long-run evidence on accuracy, and a contractor putting field decisions on it should build its own verification sampling rather than trust vendor claims
  • Answers with citations do not carry contractual weight; an RFI response or a specification still governs, so the tool reduces search time without reducing the contractual review burden

x.ai

  • API pricing is per-token/per-unit, e.g. grok-imagine-image-2.0 costs 0.04 USD per image and text to speech costs 15.00 USD per 1M characters, not a flat subscription

Answered from the vendors’ own pages

Trunk Tools: Does it replace Procore?

No. It reads from Procore or Autodesk Construction Cloud and adds retrieval and review on top. You still pay for the document platform.

Trunk Tools: What does it cost?

Trunk Tools does not publish pricing. Expect a quote scoped by project, users and which modules you take.

Trunk Tools: Can it be wrong?

Yes. It cites its source, which lets you check, but if the document set contains superseded drawings it will answer from them. Document control discipline is a prerequisite, not an optional extra.

Trunk Tools: Can field staff use it without the app?

Yes. TrunkText answers questions by text message, which is the main reason foremen adopt it.
