Mistral
MistralAI-User
Le Chat fetching a page to answer someone's question.
When you see it: Someone asked Mistral's assistant something and it opened your page.
How we check it is really Mistral
- 01
The user agent has to contain MistralAI-User.
- 02
The address is compared against Mistral's published ranges, which we refetch every six hours.
Mistral publishes no reverse DNS record, so an address outside the list is recorded as unverified rather than as a forgery — the list may simply be behind.
What each result means
- verified
- The address matched Mistral's own published records. This really was them.
- unverified
- We could not confirm it, and that is all it means. The operator may publish nothing to check against, a published list may be behind the addresses actually in use, or DNS may simply have been slow. It is not an accusation.
- spoofed
- The address belongs to somebody else — its own reverse DNS record resolves to a different owner. That is positive evidence of a forgery rather than a failure to find evidence, which is why it is reported as its own result and never folded into the row above.
The distinction costs nothing to make and is the reason these numbers can be shown to someone who will ask where they came from. A report that cannot separate “we do not know” from “this was faked” invites exactly one question it cannot answer.

User agent
MistralAI-UserMatched as a token, not as a full browser string. Mistral adds and changes the version and product text around it without notice, so a filter pinned to the whole header stops working the first time they bump a version while one matching MistralAI-User keeps working. The same string is what Mistral names in robots.txt.
Mistral's other crawlers
Mistral sends 3 crawlers, each with its own token and its own job. They are counted separately for that reason — the tokens differ by a few characters and what the fetch means does not, so folding them into one operator row would let indexing look like AI interest.

Your analytics never mentioned MistralAI-User because it cannot see it.
This crawler takes your HTML and leaves without running a line of JavaScript, so a browser tag records nothing. TrueStat reads it server-side, checks the address, and shows you which pages it fetched — including the ones that returned a 404.
