AI browser from Perplexity built on Chromium: the built-in assistant reads tabs, answers questions about the page, fills out forms, and completes purchases. The browser is free; background agents are on the Max plan.
Facts
- The vendor is Perplexity AI (USA). Comet is built on Chromium and launched on 09.07.2025 for Windows and macOS, 20.11.2025 for Android, and 18.03.2026 for iOS; the mobile app publisher in the App Store is Perplexity AI Inc. (Wikipedia, App Store).
- At first, the browser was available only to subscribers of the most expensive plan; on 02.10.2025, Perplexity opened free downloads worldwide while keeping background assistants for Max subscribers (CNBC 02.10.2025, TechCrunch 02.10.2025).
- The assistant lives in the sidebar: it keeps the context of open tabs, answers about the page, runs deep research, fills out forms, and completes purchases. Background agents and the email assistant are included in the Max plan for $200 per month; regular Pro is $20 (TechCrunch 02.10.2025, 2026 plan reviews).
- Security: LayerX Security researchers demonstrated the CometJacking attack in 2025, which exfiltrated a user's personal data to an attacker's server. Perplexity initially marked the report as inapplicable, then later told Time that it had found and fixed the vulnerability itself (Wikipedia, Time).
