Perplexity Comet reviewIs Perplexity Comet worth it?
It depends on what you need it to do. Perplexity Comet is an AI browser. Price as of November 2026: from $17/mo. It's worth it if you want an AI browser that's free on Mac, Windows, iPhone and Android and does great research. The main catch: frequent agent tasks need a paid plan, and free limits aren't published. Opera Neon is the better choice if you want a desktop browser built around an agent that can also run tasks on a schedule.
Our verdict
Comet is the best AI browser for most people: it's free on every platform and excellent at research, and it can work through sites for you. Frequent agent work needs Pro, and security researchers have shown prompt-injection attacks against AI browsers including Comet, so be careful when it's logged in to sensitive accounts.
Choose Perplexity Comet if you want an AI browser that's free on Mac, Windows, iPhone and Android and does great research.
