What it does, concretely

Browsing the web takes time: reading long articles, comparing products across multiple tabs, managing emails while researching. Perplexity Comet is a Chromium-based browser that integrates an AI assistant directly into the interface, with no extension to install.

In practice, a side panel (the Comet Assistant) opens on the right of any page. You can ask it to summarize the displayed article, compare offers across open tabs, or answer questions about visible content, without copy-pasting. The agentic mode (Comet Agent) goes further: it navigates, clicks, fills in forms, and executes multi-step tasks on your behalf, such as booking a service or sorting emails.

Comet suits people whose days revolve around monitoring, reading articles, research, or managing repetitive online tasks. Familiar Chrome extensions remain compatible, making the switch from Chrome straightforward.

It is less suited to users who work primarily offline, who have strict confidentiality requirements for sensitive professional data, or who simply do not need daily AI assistance.

What it offers

  • ·Comet Assistant side panel: answers questions about the open page and summarizes content without copy-pasting.
  • ·Agentic mode (Comet Agent): navigates, clicks, and fills in forms to execute multi-step tasks on your behalf (consumes credits depending on your plan).
  • ·Voice search: hands-free commands via an integrated speech recognition system.
  • ·Multi-tab synthesis: query the assistant across several open tabs simultaneously to compare or cross-reference information.
  • ·Automatic translation: translates page content into the user's language without manual action.
  • ·Native tracker and ad blocking: adjustable in privacy settings.
  • ·Comet Plus: access to premium press content from partner publishers in assistant answers ($5/month as an add-on, included with Pro and Max plans). (paid)
  • ·Background Assistant: delegates long-running tasks (price tracking, email reply drafting) while you work on something else. (paid)
