The short version

  • Each has a real cost: eSUB limited to commercial subcontractors; not suitable for general contractors or non-construction industries; 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: eSUB covers Mobile task management, Trunk Tools covers Question answering with citations.
  • Prices and features above were last checked on 1 September 2026.

  • A team that has just received a revised drawing set and needs to know which in-progress work is now affectednot eSUB

Where each one falls short

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

eSUB

  • Limited to commercial subcontractors; not suitable for general contractors or non-construction industries
  • Custom pricing with no transparent public pricing makes budget planning difficult for prospective customers
  • Narrow candidate list with only one direct competitor (Procore) in the space
  • May have smaller feature set compared to enterprise construction platforms

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by the discipline of the underlying document control, and on a project with stale drawing revisions it will cite superseded sheets with the same confidence as current ones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

eSUB: What is eSUB designed for and who is the primary user?

eSUB is a mobile-first construction management platform built exclusively for commercial subcontractors. It connects the field to the office through mobile apps and web interfaces for creating, tracking, and managing documents and daily activities.

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.

eSUB: What key features does eSUB Cloud include?

eSUB includes submittals, change orders, RFIs, daily reports, mobile app functionality, email integration, field notes, time cards, project management, document management, time tracking, and job costing capabilities.

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.

eSUB: Does eSUB offer a free trial?

Yes. eSUB offers a 14-day free trial as well as customized demos. The demo includes a 45-minute guided walkthrough in a staged demo project.

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.

eSUB: How does eSUB pricing work?

eSUB Cloud pricing depends on user count and modules required; quotes are provided on a customized basis. No implementation fees apply for standard scopes, and no per-job charges are assessed. Updates are included in the subscription.

Source

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