Summary
Perplexity's agentic browser, where an assistant sits beside every tab and can act on the pages you are looking at.
Description
Comet is Perplexity's web browser, built around the assumption that an AI assistant should be part of the browser rather than a website you visit. A persistent sidebar sees the page you are on, so questions can be about this — this article, this dashboard, this checkout — without copying anything into a chat box.
What it changes
- Context-aware answers. Ask about the current tab, a selection, or the set of tabs you have open.
- Agentic actions. Comet can carry out multi-step tasks in the browser — comparing options across sites, filling forms, working through a booking — with you watching.
- Search that answers. Perplexity's cited, source-linked answers replace the default results page.
- Session summarisation. Long research sessions can be condensed into notes rather than a wall of open tabs.
Practical notes
It is built on Chromium, so extensions and profiles carry over. Agentic browsing genuinely reduces tedious multi-tab work, though anything involving credentials or payments deserves supervision. Available on desktop and mobile, free with a Perplexity account and expanded limits for subscribers.
