Perplexity Comet review

Comet ranks first because it pairs a free, full browser with an assistant built to act, not just chat. Perplexity's help center describes the Comet Assistant as a side panel for questions and tasks, and its enterprise docs confirm the assistant can control the browser, click, open pages and fill forms, either with confirmation each time or with an Always Allow setting. It is Chromium-based, so bookmarks, translation and most Chrome extensions carry over, and it adds a built-in ad blocker, a Gmail connector and Personal Search over your own history. Apps exist for Mac, Windows, iOS and Android, the widest spread on this list. The catch is that heavier use and the top models sit behind Perplexity Pro, shown at $17 a month when billed annually, or Max at $167. Search also defaults to Perplexity. For most people who want an assistant that can do the clicking, Comet is the easiest place to start because it costs nothing to try.
