FETCH · Perplexity AI

Perplexity-User

Perplexity live retrieval

Bot that fetches a URL because a Perplexity user just asked a question requiring it — including the 'Pages', 'Shop', and follow-up modes. Each request is tied to an active user query.

Considerations

  • Per Perplexity's own current documentation, this fetcher 'generally ignores robots.txt rules' because requests are user-initiated. The control surface that actually works is IP-range / reverse-DNS blocking — or a server-level rule.
  • Distinct from PerplexityBot (index). Blocking PerplexityBot does not block Perplexity-User.
  • Uses a real headless browser for some flows.

# Note: this bot may ignore the directive for user-triggered fetches.
# IP-level rules are the actual control.
