Comet Browser

Perplexity Comet Browser

Comet is Perplexity's Chromium-based web browser, launched in July 2025. Unlike browser AI features bolted on as extensions (Google's Gemini sidebar, Microsoft Copilot in Edge), Comet treats AI as a first-class component of the browser itself - the address bar, new tab page, and page context are all AI-aware by default.

Key Features

AI-Native Address Bar

Type a question in the address bar instead of a URL. Comet answers directly with Perplexity, skipping the search results page entirely. For navigational queries (specific sites), it still opens URLs normally.

AI Sidebar

Persistent sidebar that knows what page you are currently reading. Ask it to summarise the page, explain a concept from the article, or find related information. Context-aware - it reads the page without you copying text.

Agentic Web Browsing

The most distinctive feature: tell Comet to complete multi-step tasks - "Book me a dinner reservation at any Japanese restaurant in Soho, London for 2 people Friday 8pm." Comet browses, forms, and submits on your behalf. Available for Pro users.

Perplexity as Default Search

All web searches go to Perplexity's answer engine rather than Google. Can be changed to Google or Bing in settings, but Perplexity is the default and deeply integrated into the new tab page.

Market Positioning

Comet directly challenges Chromium browsers from Google (Chrome) and Microsoft (Edge). The strategic logic: Perplexity wants to own the search relationship, and the browser is where web search happens. By embedding Perplexity into the browser layer, it can capture users who would otherwise default to Google.

Status as of June 2026

Comet launched in early access in July 2025. As of mid-2026, it is available for macOS and Windows. Mobile versions are in beta. Download is free; agentic features require Perplexity Pro.
