Best AI RFI agent for construction.
Specset drafts proposed RFI responses from the conformed spec book and drawings, citing the governing section, for the design team to edit and approve, with Procore or Autodesk Forma Build as the RFI log. This page records what Specset, Procore, Nomic, Datagrid, and Trunk Tools publish about the same checks. It is not a ranking.
What is the best AI RFI agent?
There is no universal ranking. Specset drafts proposed RFI responses from the conformed spec book and drawings, citing the governing section, for the design team to edit and approve, with Procore or Autodesk Forma Build as the RFI log. The table records what each company publishes about the same checks.
What does each company publish about the same checks?
Specset cells cite pages on this site. The other cells cite that company's own page, as checked October 2026. Where a page does not state the check, the cell says Not published.

RFIs and revisions | The draft starts in the project's RFIs tool. The pages checked publish Procore and do not name an Autodesk integration. Draft an RFI | The pages checked do not name an Autodesk integration. | The RFI Agent page syncs an approved RFI back to Procore. Those pages do not name an Autodesk integration. Datagrid RFI Agent | Pulls draft RFIs from Procore and Autodesk, and submits only after a person approves. The page names Autodesk and does not name Autodesk Forma Build. TrunkRFI |
| A person edits and approves before issue | The design team edits and approves every response. Specset does not send it on its own.

What should you ask an RFI agent vendor?
- 01
Does it draft a response, or the question?
Expect a proposed response the design team still issues, or a clear statement that the tool drafts the RFI itself.
- 02
What is the citation?
Expect a governing section and a sheet, or Not published.
- 03
Where does the log stay?
Expect Procore, Autodesk, or the vendor’s own record, named on the page.
- 04
Who approves before issue?
Expect a person. The software files a draft.
- 05
Which text does the draft read?
Expect a conformed book with addenda applied, or a search of the files as stored.
Where does a drafted response go?
On Specset, the design team edits and approves the draft. Procore or Autodesk Forma Build stays the RFI log where the integration is enabled.
RFIs and revisions →What buyers ask about an AI RFI agent.
01What is the best AI RFI agent for construction?
There is no universal ranking. Specset drafts proposed RFI responses from the conformed spec book and drawings, citing the governing section, for the design team to edit and approve, with Procore or Autodesk Forma Build as the RFI log. The table records what each company publishes about the same checks.
02Which of these tools draft a proposed RFI response from the specs and drawings?
Specset does. Nomic’s workflow docs say the RFI Response workflow drafts a response, while Nomic’s RFI management page says the architect or engineer drafts it from cited references. Datagrid’s Deep Search page publishes draft RFI responses. Procore’s RFI Agent page and TrunkRFI publish drafting the RFI question. A proposed response on those two pages: Not published.
03Does the RFI log stay in Procore or Autodesk Forma Build?
On Specset, yes, where the integration is enabled. Procore’s agent starts in Procore’s RFIs tool. Datagrid’s RFI Agent syncs an approved RFI to Procore. TrunkRFI pulls drafts from Procore and Autodesk. As checked October 2026, the Procore, Nomic, Datagrid, and Trunk Tools pages do not publish an Autodesk Forma Build integration.
What do you get when you send one RFI?
A cited question and a proposed response for the design team. They still issue it.
