Is PerplexityBot blocked on your site?

PerplexityBot is the Perplexity crawler that builds the index the model answers from. If your robots.txt blocks it, that engine cannot read your pages, and a page it cannot read is a page it can never cite.

Free, no sign-up. We fetch one public file and read it. Nothing is stored.

Questions

What does PerplexityBot do?

Should I block PerplexityBot?
Usually not. This crawler is how Perplexity reaches your pages when answering a question, so blocking it removes you from answers you could have been cited in.
Is this check free?
Yes, and there is no signup. We fetch one public file, robots.txt, and read the rules for this user-agent. You see the full result, including every failure we find.
