What MistralAI-Training does

MistralAI-Training crawls public web content to build datasets for training Mistral's generative AI models. Mistral says it isn't used for search indexing or for answering live questions.

Does MistralAI-Training follow robots.txt?

Yes. Mistral says webmasters can disallow MistralAI-Training in robots.txt. It describes no other opt-out.

How to block or allow MistralAI-Training

Block it from the whole site:

User-agent: MistralAI-Training
Disallow: /

Keep it out of one folder only:

User-agent: MistralAI-Training
Disallow: /private/

A crawler that finds a group with its own name follows only that group and ignores User-agent: *. If your * group disallows paths such as /admin/, repeat those lines in the MistralAI-Training group. robots.txt works per host, so add the rules to each subdomain you want covered.

Test the result with the robots.txt checker, or write a new file with the robots.txt generator.

What blocking MistralAI-Training changes

Mistral stops collecting your content for model training. Its search and live answers use other bots, so blocking this one alone keeps you in them.

Where to see MistralAI-Training visits

Most bots never appear in Google Analytics. Many don't run JavaScript, so the analytics tag never loads, and Google Analytics 4 automatically excludes traffic from known bots and spiders. Your server or CDN logs record every request with its user agent, so search them for the bot's name.

OneLence AI visibility shows which pages AI crawlers read and fetch for answers, next to the visitors AI assistants send you and the ones that convert.
