The short version

  • Each has a real cost: Kahua no standard pricing tiers published; all pricing is custom and quote-based; 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
  • They diverge on capability: Kahua covers Project management, Trunk Tools covers Question answering with citations.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

Kahua

  • No standard pricing tiers published; all pricing is custom and quote-based
  • Pricing varies by organization type, program or construction scale, selected package, and deployment environment
  • Implementation costs for data migration, integrations, training, and configuration scoped separately and included in quote

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by the discipline of the underlying document control, and on a project with stale drawing revisions it will cite superseded sheets with the same confidence as current ones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

Answered from the vendors’ own pages

Kahua: How much does Kahua cost?

Kahua does not publish standard pricing. Costs vary by organization type (Owners/Program Managers, General Contractors, Specialty Contractors), program scale, selected package, deployment environment, and implementation requirements. Customers must request pricing quotes.

Source
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.

Kahua: What package options does Kahua offer?

Kahua offers three main package categories: Owners and Program Managers, General Contractors, and Specialty Contractors. Additional specialty apps and suites including capital planning, analytics, asset management, and safety can extend the base solution.

Source
Trunk Tools: What does it cost?

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

Kahua: Are implementation and integration costs included in Kahua pricing?

Implementation details including data migration, integrations, training, and configuration are scoped based on requirements and clearly identified in the custom quote provided.

Source
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.
