Comet Review 2026 – Perplexity's AI Browser

Comet is Perplexity's attempt to put an assistant not beside the web but inside the act of browsing it — one that can read your tabs and carry out multi-step tasks across them.

What is COMET BROWSER?

A Chromium-based browser with Perplexity's search and assistant built into the core of the interface. It answers questions about open tabs, compares pages, fills forms and works through tasks that would otherwise mean a dozen clicks.

Key Features

• An assistant with context on every open tab.
• Perplexity's cited answer engine as the default search.
• Agentic tasks — booking, comparing, summarising across sites.
• Chromium base, so Chrome extensions and imports work.
• Built-in ad and tracker blocking.

Pricing

Free to download, with the deeper assistant features tied to a Perplexity Pro or Max subscription.

Who Should Use it?

• Heavy researchers with twenty tabs open.
• Existing Perplexity subscribers.
• People who want an agent that can act, not just answer.
• Chrome users curious about an AI-first browser.

Pros

• Understands your open tabs without copy-pasting
• Cited answers built into search
• Chrome extensions still work
• Real task automation, not just chat

Cons

• Best features need a paid Perplexity plan
• A browser that reads your tabs is a large trust decision
• Younger and less stable than Chrome or Firefox

Alternatives

• Brave Leo
• Microsoft Copilot
• Perplexity AI
• ChatGPT

Is it Safe?

The assistant can see page content and act on your behalf, which is a much wider permission than a chat window. Read Perplexity's policy on what is retained, and be deliberate about which sites you let it act on.

Frequently Asked Questions (FAQ)

Is Comet free? The browser is free; the more capable assistant features need a Perplexity subscription.

Can I keep my Chrome extensions? Yes, it is Chromium-based and supports them.

What can the agent actually do? Multi-step web tasks — comparing products across sites, filling forms, summarising several tabs at once.

Final Verdict

The most interesting AI browser so far. Worth trying if you already pay for Perplexity; think about the permissions before making it your default.
