Perplexity-User¶
Perplexity-User is one of Perplexity AI's two documented crawlers. Declared user-agent:
Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; compatible;
Perplexity-User/1.0; +https://perplexity.ai/perplexity-user)
Perplexity-User is the on-demand, user-triggered fetch path โ it fires when an end-user asks Perplexity a question that requires fetching a specific page, as opposed to background indexing (PerplexityBot).
Published IP range. Respects robots.txt per Cloudflare's testing.
Separating bots by activity (user-fetch vs index/train) is one of the five operator norms Cloudflare names in the 2025-08-04 post โ it lets site owners allow one and deny the other. See concepts/declared-crawler.
