What is Perplexity-User?
Perplexity-User is Perplexity's on-demand AI fetcher. Fetches your page live when a Perplexity user asks.
What does Perplexity-User do with your content?
Fetches your page live when a Perplexity user asks. Like most AI crawlers, Perplexity-User reads your pages as plain HTML — it does not run JavaScript — so content that only appears after scripts execute is invisible to it.
Should you block Perplexity-User?
Blocking Perplexity-User makes your business invisible to Perplexity's AI when customers ask it for recommendations. If you want to be found, allow it; block it only if you have a specific reason to keep Perplexity's AI away from your content.
How do you allow or block Perplexity-User in robots.txt?
Add one of these snippets to the robots.txt file at the root of your site. The first explicitly allows Perplexity-User everywhere; the second blocks it completely.
# Allow Perplexity-User
User-agent: Perplexity-User
Allow: /
# Block Perplexity-User
User-agent: Perplexity-User
Disallow: /Is robots.txt enough?
Not always. CDNs and firewalls (Cloudflare in particular) can block crawlers at the network level regardless of what robots.txt says — Cloudflare blocks AI crawlers by default for many accounts. If you want Perplexity-User to reach your site, check your CDN's bot settings too. SeeGeo's free audit checks both.
