The short version

  • Only STACK Construction Technologies has a free tier, so it costs nothing to try first.
  • Each has a real cost: STACK Construction Technologies takeoff and Estimate is priced per user at $249 per user per month, so cost scales linearly with estimators; 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: STACK Construction Technologies covers Digital takeoff, 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.

STACK Construction Technologies

  • Takeoff and Estimate is priced per user at $249 per user per month, so cost scales linearly with estimators
  • The full platform combining takeoff, estimating and field management starts at $298 per user per month
  • Field and project management is sold as a separate Build and Operate product starting at $49 per user per month rather than bundled with takeoff
  • The Build and Operate product offers only a two-week free trial, with the free version limited to Takeoff and Estimate

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by the discipline of the underlying document control, and on a project with stale drawing revisions it will cite superseded sheets with the same confidence as current ones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