- **name:** Perplexity Comet (assistant/agent)
- **operator:** Perplexity
- **purpose:** agentic-browsing
- **ua_substring:** 
- **robots_token:** (none — agentic browser; no published robots.txt token)
- **respects_robots:** no
- **verify:** no stable user-agent and no verifiable identity layer; Comet runs inside the user's browser session and presents like ordinary Chromium traffic. Distinct from PerplexityBot/Perplexity-User (which are cloud bots verifiable by IP range + perplexity.ai in the UA).
- **notes:** Perplexity's Comet is a Chromium-based browser fork that runs locally and performs multi-tab agentic actions inside the user's session. Unlike Perplexity's cloud crawlers, it has no verifiable identity layer at the network level — included here per the agentic-browser taxonomy, verifiable by IP/signature only.
- **canonical_name:** Comet

- **first_seen_date:** — (verify-against-primary-at-build)
- **last_verified_date:** 2026-06-15
- **block_vs_allow_recommendation:** conditional — acts inside a real user's browser session with no verifiable identity layer; it is not a bulk crawler and cannot be reliably blocked by robots.txt or UA. Manage via session-level / bot-management controls if agent actions are a concern.
- **citation_referral_value:** medium (acts on a user's behalf in-browser; can surface and act on your page for that user)
- **cloudflare_verified_category:** — (verify-against-primary-at-build)
