Perplexity Comet

Comet is Perplexity’s AI-native browser, putting an assistant in every tab that can search, summarize, compare and complete multi-step web tasks.

Overview

Launched in 2025, Comet builds Perplexity’s answer engine directly into a full Chromium browser. Any page becomes askable: highlight text, ask follow-ups, and get cited answers drawn from the page and the wider web, without copy-pasting into a separate chatbot.

Comet Assistant goes further by acting on your behalf, navigating sites, filling forms, managing email and calendar and completing purchases under supervision. Comet Plus extends the model with premium journalism and research sources, and the product has become the reference point for what a consumer AI browser can be. Because it inherits Chrome extension compatibility, existing workflows and password managers continue to work unchanged. Collections and threads keep research organized long after a task finishes.

Key Features

• Assistant in every tab with page-aware cited answers
• Agentic task completion across websites and web apps
• Email and calendar management through connected accounts
• Comet Plus premium content from publishers and research sources
• Focus mode that organizes research into threads and collections
• Import from Chrome for a familiar setup with extensions
• Privacy controls with per-site permissions for agent actions

Pricing

Comet is free to download and use with core browsing and search features. Agentic capabilities and Comet Plus content are bundled into Perplexity’s Pro subscription tiers, and enterprise plans provide managed deployment and admin controls. Bundling the browser with existing Perplexity subscriptions makes the cost easy to justify for people already paying for better answers.

Who Is It For

Comet targets researchers, students and professionals who want answers and action in one place instead of juggling search engines and chatbots. It is especially useful for people whose work starts with a question and ends with a completed web task. Shoppers and travelers also benefit, as the assistant can compare options and complete routine tasks across multiple sites.

FAQ

Is Perplexity Comet free to use?

Yes, Comet is free for everyday browsing and search. The most powerful agent features and premium content require a paid Perplexity plan.

Does Perplexity Comet offer an API?

Perplexity offers the Sonar API for developers who want the underlying answer engine in their own products, though the browser itself is a consumer application rather than an API surface.

How does Perplexity Comet compare to alternatives?

Comet leads on search quality and citations among AI browsers, while competitors emphasize either open-ended agent autonomy or tight ecosystem integration. For question-driven work it is the most polished option available. For users whose work starts with questions, Comet’s search-first design outperforms browsers that treat AI as an afterthought bolted onto a traditional interface.
