Perplexity Comet is a revolutionary AI-powered web browser based on the Chromium framework, designed to transform the internet from a passive display of pages into an interactive, task-driven workspace.
Introduction
The traditional web browser has remained largely unchanged for decades—a window into which we type URLs and click links. Perplexity Comet is the first true AI-native browser designed to break this mold by acting as a proactive partner in your online life. Built by the team at Perplexity AI, Comet integrates an intelligent “Comet Assistant” directly into the browsing core, enabling it to understand the context of every page you visit. Whether you are a researcher synthesizing hundreds of sources, a shopper comparing products across a dozen sites, or a professional managing a chaotic inbox, Comet eliminates the friction of manual tab-switching and copy-pasting. It is the internet’s “digital brain,” learning your habits to automate the routine and let you focus on what truly matters.

Review
Perplexity Comet is a revolutionary AI-powered web browser based on the Chromium framework, designed to transform the internet from a passive display of pages into an interactive, task-driven workspace. Launched in July 2025 and expanded to mobile platforms in late 2025, Comet is not just a search tool; it is a full-fledged AI Agent that lives inside your browser. It leverages Perplexity’s powerful AI models (including Sonar and R1) alongside external frontier models like Claude 4 and GPT-5 to summarize content, manage complex workflows, and execute real-time actions.
Unlike traditional browsers, Comet introduces a “Workspace” model that replaces standard tabs with a unified interface where the AI tracks your research, active tasks, and queries simultaneously. Its most innovative feature is agentic execution, allowing the browser to navigate websites, book meetings, and even complete authorized transactions on your behalf. While its advanced capabilities are primarily reserved for Pro and Max subscribers, Comet’s free availability for basic AI-enhanced browsing marks a significant shift toward the “agentic” future of the web.
