About Perplexity Comet
Comet is Perplexity's browser with contextual assistance and an agent for navigating sites, filling forms and completing multi-step web tasks. Connected accounts can extend its access. The browser is free to download, but Perplexity's current subscription table excludes browser-agent queries from the free plan and gives paid plans usage limits. Verify the entitlement for your account before relying on automation. The provider warns that suspicious page content can mislead requests and advises reviewing actions and stopping unexpected behavior. Browser automation and connected-account handling were not tested.
