Perplexity Comet

Perplexity Comet is a Chromium-based AI browser developed by Perplexity AI, first launched in limited access in July 2025 before opening to all users globally. It is available on macOS, Windows, iOS, and Android. The browser embeds the Comet Assistant — powered by Claude Opus 4.6 for Max subscribers — directly into every new tab, enabling it to read across all open tabs, fill web forms, compare prices, manage tab sessions, and complete multi-step research tasks without the user manually copying and pasting between windows. Unlike Arc or standard Chrome, Comet is architecturally designed around agentic browsing from the ground up rather than layering AI on top of an existing browser shell.

The core technical distinction is multi-tab intelligence: Comet's assistant can simultaneously observe the DOM and visible content of all open browser tabs, extract structured data from each, and transfer that data between tabs automatically. In a tested workflow comparing three SaaS pricing pages, Comet assembled a structured comparison table without a single manual copy-paste — a task that typically takes four to six minutes across standard tabs. Background Assistants extend this further, allowing multiple agents to work on asynchronous tasks while the user focuses on other windows. For Max subscribers, the Email Assistant feature can be CC'd on email threads to handle scheduling and draft replies directly from the Comet interface.

Comet is not the right tool for users with strong data privacy requirements: Perplexity collects full browsing history and search behavior from Comet to build advertising profiles. Developers and teams that process proprietary or client-confidential web data should treat this as a hard constraint before adopting Comet as a primary browser. The most capable AI agent features — Claude Opus 4.6 reasoning and Email Assistant — require the $200/month Max subscription, which limits Comet's agentic ceiling significantly for free and Pro users.

Built on Chromium, Comet supports the full Chrome extension ecosystem and can import bookmarks, saved passwords, and extension configurations from Chrome in a single step — making migration from Chrome a low-friction decision for users who are not privacy-sensitive.

Perplexity Comet is an AI Agent browser that replaces passive tab browsing with agentic task execution across multiple browser windows simultaneously. It runs on Chromium — meaning Chrome extensions, passwords, and bookmarks import directly — while adding a built-in Comet Assistant capable of researching, comparing, form-filling, and managing email across active tabs. Max subscribers access Claude Opus 4.6-powered reasoning and Email Assistant. Core browser features are free for all Perplexity account holders globally.

Compared to managing research across standard Chrome tabs, Perplexity Comet reduces multi-source comparison tasks from four to six minutes of manual work to under sixty seconds of agent-assisted extraction — particularly for financial research, product comparisons, and multi-source literature review. The primary limitation is the $200/month Max subscription required to unlock Claude Opus 4.6 reasoning and Email Assistant, which places the most differentiated capabilities well outside the reach of most individual users.
