Perplexity Comet — the AI browser

Perplexity Comet is a full web browser that treats AI as a first-class citizen. It reads, summarizes, and acts on pages you visit.

30 min · Reviewed 2026

For twenty years your browser was a passive window onto the web. Perplexity Comet, released in 2025, is the first widely-used browser that treats AI as part of the browser itself — not a sidebar, not an extension, but integrated into the tab bar and address bar.

What makes Comet different

Ask questions of the current page or selection without leaving the tab.
An AI agent that can complete tasks across multiple tabs (compare prices, fill forms, summarize a research session).
Memory across sessions — Comet remembers what you've been working on and picks up the thread.
Chromium-based so every website still works.

When it matters for real work

Research workflows are where Comet actually earns its keep. Open 20 tabs on a topic, ask Comet to synthesize them into a brief with cited sources, and it does. For high-schoolers doing term papers, this changes the shape of the research process — but it also changes what 'research' means, which raises the question of what you actually learned.

The agentic angle

Comet is a browser agent — meaning it can perform multi-step tasks across web interfaces. Book a flight. Re-up a prescription. File an expense report. This puts Comet in direct competition with OpenAI's Operator and Anthropic's Computer Use, but with a critical advantage: it runs locally in your browser session so it already has your logins.

Try it

Install Comet (it's free to try; full features need Perplexity Pro). Open three tabs about a current news story. Ask Comet: 'synthesize these three perspectives and cite which claim came from which source.' You'll get a reasonable first draft — and you'll see its limits.
