What it is used for

Handles user-initiated actions: when a user asks a question, it may visit a page to help answer and link to it. Perplexity says it is not used for crawling or training data. Opens one page because a person (or an answer being generated) needs it. The operator may treat robots.txt differently for these requests.

What happens if you block it

Because a user requested the fetch, Perplexity says it generally ignores robots.txt rules for this agent.

How to allow or block Perplexity-User

Add one of these groups to the robots.txt at the root of your domain. A group that names the bot overrides a general User-agent: * group.

What we see on our own sites

No request identifying as Perplexity-User has been recorded in the last 30 days, so there is nothing to show yet. We never fill this in with estimates.

Counts come from the websites we operate; they hold no IP addresses or URLs, and a user agent is only a claim. See the bot traffic data and the methodology.
