The short version

  • Only Buildxact has a free tier, so it costs nothing to try first.
  • Each has a real cost: Buildxact 15% discount applied only to annual billing; 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

Where each one falls short

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

Buildxact

  • 15% discount applied only to annual billing
  • Advanced AI add-ons require additional per-month fees

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by the discipline of the underlying document control, and on a project with stale drawing revisions it will cite superseded sheets with the same confidence as current ones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