Definition
Comet is an AI-native web browser built by Perplexity that integrates its answer-engine search, an AI sidebar assistant, and agentic browsing features directly into the browsing experience, letting users ask questions about pages they're viewing or have an AI agent complete multi-step tasks across websites.
Overview
Comet, released by Perplexity in 2025, is built on a Chromium base but positions AI as a first-class part of the browser rather than an add-on extension. Its core features include an always-available AI sidebar (Perplexity Assistant) that can summarize or answer questions about the current page, compare open tabs, or synthesize information across multiple browsing sessions, and Perplexity's search-and-answer engine integrated directly into the address bar in place of a traditional search engine. Comet's more distinctive feature is agentic browsing: the assistant can be asked to complete multi-step tasks that involve navigating and interacting with websites on the user's behalf — for example, comparing prices across shopping sites, filling out and submitting forms, managing email or calendar tasks, or booking a reservation — acting somewhat like a browser-based version of computer-use agents, operating within the actual rendered web pages rather than through separate APIs. This raises both capability and safety/trust considerations distinct from a standard chat assistant, since the agent is taking real actions (clicks, form submissions, purchases) inside live websites. Comet is part of a broader trend of AI companies building or acquiring browsers as a platform for agentic AI (alongside efforts like OpenAI's ChatGPT Atlas and other browser-embedded agent products), reflecting a bet that the browser — where most knowledge work and online tasks already happen — is a more natural home for persistent, context-aware AI assistance than a separate chat window, and a strategic extension of Perplexity's core search-and-answer product into a full browsing surface it controls end to end.
