Perplexity Comet

Also known as: Comet, Comet browser, Comet AI browser

Perplexity's agentic AI browser, available free on Mac, Windows, Android, and iOS. It embeds an AI assistant directly into every page you visit, so you can ask questions about what you're reading, delegate multi-step tasks, and complete workflows without switching between tabs and chat windows.

Most AI tools sit next to your browser. Comet builds the AI into the browser itself. When you visit a page, a context-aware assistant is available right there. Highlight text to get an explanation, ask it to compare prices on an e-commerce page, or hand it a multi-step task like researching candidates before a meeting and drafting a prep brief, without ever opening a separate app or copy-pasting between windows.

Comet is built on Chromium (the same open-source base as Chrome) and launched on desktop in mid-2025 before expanding to Android and iOS in early 2026, where it's now available to anyone for free. Its differentiated angle is Perplexity's answer-engine heritage: responses are citation-grounded, meaning claims link back to real sources rather than being generated freely. That matters especially when the agent is taking actions on your behalf, since accuracy compounds.

For builders, the more interesting layer is Comet as a distribution wedge. Perplexity lets paid subscribers choose which AI model powers the browser agent, which is unusual. That model-picker positioning reflects a broader bet: that the browser, not the chat app, becomes the dominant surface for agentic AI. Enterprise deployments via MDM (a way for IT teams to push software to company devices at scale) are already available, signaling Comet is being taken seriously beyond the individual power-user market.
