# Perplexity-User

> Perplexity-User is the agent Perplexity uses to fetch a specific page in real time when a user's question requires it. Because the request is user-initiated, it generally ignores robots.txt, so a robots.txt block will not stop a direct user-driven fetch.

Perplexity-User is separate from PerplexityBot. PerplexityBot crawls to build the search index and respects robots.txt; Perplexity-User fetches on behalf of a specific user action, such as someone using Perplexity's [Comet browser](https://geotoolbox.ai/blog/perplexity-comet), and generally does not.

The practical takeaway: allow PerplexityBot so you are in the index, and do not rely on robots.txt to keep content away from a user who asks [Perplexity](https://geotoolbox.ai/blog/what-is-perplexity) about your page directly.
