The short version

  • Only Zilliz has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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; Zilliz pricing structure not publicly disclosed, requires sales contact
  • They diverge on capability: Trunk Tools covers Question answering with citations, Zilliz covers Vector indexing.
  • 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.

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by the discipline of the underlying document control, and on a project with stale drawing revisions it will cite superseded sheets with the same confidence as current ones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

Zilliz

  • Pricing structure not publicly disclosed, requires sales contact
  • Operational complexity for self-hosted Milvus deployments
  • Learning curve for those unfamiliar with vector databases
  • Limited built-in analytics compared to some alternatives

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.

Zilliz: What is the difference between Milvus and Zilliz Cloud?

Milvus is the open-source vector database that you can self-host. Zilliz Cloud is the fully managed service built on Milvus that removes operational overhead and handles scaling automatically.

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.

Zilliz: How many vectors can Zilliz handle?

Milvus and Zilliz Cloud can store and search billions of vectors through their distributed architecture that separates storage and compute layers.

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.

Zilliz: Is Milvus open-source?

Yes, Milvus is open-source under the Apache License 2.0 and is part of the LF AI & Data Foundation.

Source
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.

Zilliz: What pricing does Zilliz Cloud offer?

Zilliz Cloud pricing is not publicly listed and requires contacting their team to discuss your specific scale and use case requirements.
