How Mistral's assistant, Vibe (Le Chat), picks the brands it names

Not tracked

Attensira does not track Mistral's assistant, which Mistral's documentation calls Vibe and its news posts call Le Chat. Mistral documents three crawlers, one for search, one for live questions and one for training, so a site can stay in its search and out of its training. This guide covers what each does and what to allow.

Which user agents does Mistral document?

The answer at the top is ChatGPT's list of AI crawlers, on 4 October 2026. It names one Mistral agent, MistralAI-User; Mistral documents three, beside this. A rule written from that list covers live questions and misses search and training. Our own log recorded no MistralAI-User request in the 30 days to 4 October 2026.

Mistral's three user agents
MistralAI-User
Visits a page when someone asks Vibe a question
MistralAI-Index
Indexes for Mistral search; not used for training
MistralAI-Training
Builds training datasets; not used for search or answers

What does Mistral Vibe (Le Chat) draw on when it answers?

Mistral's assistant goes by two names: Vibe in Mistral's documentation and site menu, Le Chat in its news posts. Mistral documents more about how it reads the web than most makers: separate user agents for search, for live questions and for training.

That split is the useful part. A site can stay in Mistral's search and live answers while opting out of its training, and it can see in its own logs when a live question used one of its pages.

In short

  • Pages MistralAI-Index has indexed for Mistral search
  • Pages MistralAI-User fetches for a question
  • Separates search, live fetching and training into three crawlers

Example · a checklist from the facts on this page; Attensira does not measure Mistral Vibe (Le Chat)

How do you check what Vibe says about you?

Ask it, in every language you sell in, and look in your server logs the same day. Mistral says Vibe may visit a page to answer a question and links the source in its reply, and that visit is made as MistralAI-User. A hit from that user agent on a page means a live question just used it.

Check in Vibe4 steps
  1. 01

    Ask

    Your buyers' questions in Vibe, once in each language you sell in.

  2. 02

    Record

    Named or not, who instead, and the links it includes in its reply.

  3. 03

    Logs

    MistralAI-User hits on your pages the same day: those pages answered a live question.

  4. 04

    Allow

    MistralAI-Index and MistralAI-User in robots.txt; decide on MistralAI-Training separately.

Questions about Mistral Vibe (Le Chat)

Does Attensira track Mistral Vibe (Le Chat)?
No. Attensira reads ChatGPT, Perplexity, Claude, Gemini and Google AI Overviews, and nothing else. This page explains how Mistral Vibe (Le Chat) chooses what to recommend so you can act on it yourself; Attensira does not measure your mention rate or citations there.
Is it called Vibe or Le Chat?
Both names are in use. Mistral's crawler documentation, read on 4 October 2026, says MistralAI-User acts when users ask Vibe a question, and Mistral's site lists Vibe as its AI agent. Its news posts still called the assistant Le Chat as recently as May 2026.
Can I opt out of Mistral training but stay in its search?
Yes. Mistral documents MistralAI-Training for training datasets, separately from MistralAI-Index for search and MistralAI-User for live questions. Disallow the first and allow the other two.

Whatever it takes to win the answer.
