What is Comet?
Comet is Perplexity's AI-native browser that treats web browsing as an active, agent-driven process rather than a passive display of pages. Built on Chromium, it retains full compatibility with Chrome extensions and enterprise policies while adding a layer of agentic functionality — including automated product research, meeting scheduling, inbox triage, and multi-step task completion — that operates across tabs without requiring users to re-enter context between sessions. The business case for Comet centers on the cost of context switching. Knowledge workers who spend large portions of their day across Gmail, Google Calendar, Google Drive, and research tabs face continuous interruptions as they manually move information between applications. Comet's cross-tab memory layer and native integrations with Google Workspace mean that a task initiated on one tab — say, finding a vendor — can be completed on another without manual copy-paste. Perplexity dropped the browser's $200 per month paywall on March 18, 2026, making it free for all Perplexity account holders, with a Comet Plus add-on available at $5 per month for access to premium publisher content from partners including Wired, CNN, Fortune, and The Washington Post. Comet's compliance posture — SOC 2, HIPAA, and GDPR certification — makes it viable for enterprise deployments in regulated industries. Enterprise teams can deploy it under standard Chromium administrative policies, reducing onboarding friction. For individuals who perform only light web browsing without heavy cross-app task coordination, the agentic features add limited value over a standard browser, and the Perplexity account requirement may be a friction point for users outside its existing ecosystem. Comet is not the right tool for users who need a fully offline browser, who work primarily in non-Google productivity stacks, or whose workflows depend on browser extensions that conflict with Chromium-based environments. Agentic automation that interacts with sensitive financial systems should also be reviewed carefully, as AI-driven task execution introduces risks if workflows are misconfigured.
Comet is Perplexity's AI agentic browser that automates multi-step tasks, retains context across tabs, and integrates with Gmail and Google Calendar — free for all Perplexity users.
Comet is widely used by professionals, developers, marketers, and creators to enhance their daily work and improve efficiency.

Final Verdict
Comet is the strongest free option for knowledge workers whose productivity bottleneck is cross-application task coordination — particularly researchers, analysts, and founders who spend hours daily synthesizing content from multiple tabs. The primary limitation is that agentic features are still maturing: complex multi-step tasks occasionally produce incomplete outputs, and users dependent on non-Google productivity tools will find the integration depth narrower than advertised.
