Usually allowed, it fetches only when a person asks the assistant about your page.

What Perplexity-User is

Perplexity-User fetches pages when users ask Perplexity questions, so it can provide accurate answers and include links in responses.

Perplexity documents that this fetcher generally disregards robots.txt rules, because it acts on a direct user request rather than as a background crawler.

Like Perplexity's other agent, it does not collect training data, it serves user-facing answers only.

Controlling Perplexity-User in robots.txt

Perplexity-User acts on a direct user request and, per Perplexity, generally does not treat robots.txt as binding the way a background crawler does. The rules below express your intent, but a user-initiated fetch may still occur when a person explicitly points the assistant at your page.
