It reads a page for an AI's search or for a person who asked an assistant, and can bring visitors. Bot Protection lets it through by default; you can block it.

How to verify it

Any bot can write PerplexityBot in its User-Agent. A request is PerplexityBot only when its address is in Perplexity's published list below: check the address, not the name.

How to block it

With robots.txt, you ask it to stay out:

User-agent: PerplexityBot
Disallow: /

robots.txt is a request, not a block, and it cannot tell the real crawler from a bot wearing its name. Bot Protection verifies PerplexityBot by its address on every request and answers it as you choose on the Set-up page, per kind or for PerplexityBot alone; a bot that only wears the name is judged like any other bot.
