What this looks like in your logs
grep -i 'MistralAI-User' access.log
Mistral AI publishes no full user-agent string for MistralAI-User, so the rest of the line varies and only the token MistralAI-User is dependable. Kymo matches on that token, case-insensitively, for the same reason.
What MistralAI-User does not do
MistralAI-User does not guarantee a visit, because a read only becomes a visit if a person clicks the citation that came out of it.
MistralAI-User does not crawl on a schedule, because it only requests a page when a person has already asked something that needs it.
Mistral AI publishes no documentation for MistralAI-User at all, so no crawl frequency and no compliance statement exists to quote.
How Kymo classifies it
Kymo files MistralAI-User under Mistral AI as ai_answer, classified from the HTTP request on the server rather than from anything running in a browser.
A hit from MistralAI-User counts on the AI Visibility page, which is the only page that counts crawls at all. An answer crawl is the only kind a person can click through from, so it is the only kind that belongs beside a visitor number.

Allow it or block it
Verify against Mistral documentation before publishing this section.
| Allow it if | Block it if |
|---|---|
| You want Mistral AI to read your live page when a person asks about you, which is the crawl most likely to send a real visitor. | You do not want your page read during a live question. Check the compliance row first: a fetcher started by a person may need an edge rule rather than a robots.txt rule. |

Questions
How do I know a request claiming to be MistralAI-User is genuine?
Mistral AI publishes no verification method for MistralAI-User, so the user-agent string is the only signal available, and anyone can send one. Treat a claimed MistralAI-User request as unproven.
Does blocking MistralAI-User affect my Google ranking?
No. A Google ranking is decided by Googlebot, which is a separate crawler. MistralAI-User fetches a page after a person has already asked Mistral AI a question, which happens well after ranking and takes no part in it.
Will I see MistralAI-User in Google Analytics?
No. Google Analytics runs a JavaScript tag in a visitor's browser, and MistralAI-User reads your HTML and leaves without running any script. Server-side logging is the only way to record it.
Does MistralAI-User send traffic back to my site?
Yes. MistralAI-User builds an index that Mistral AI cites its sources from, and a citation there is a link a person can click. A crawl is still not a visit, so expect the read count to run far ahead of the click count.

MistralAI-User arrives because a person just asked Mistral AI something, and a browser tag never runs in time to record the moment.
Kymo reads the HTTP request on your server, so a crawler that never runs JavaScript is still recorded. You see which bots reached the site, which pages they took and how often, next to your human traffic.
