Comet is a Chromium browser that does not produce files and has no watermark issue; however, it is known to have a prompt injection vulnerability risk, and both official and third-party evaluations do not recommend using it for banking account or other sensitive data operations.

Max's maximum limit
What Sets Us Apart
Most popular choice. 15 times the price of Plus, but with a 4x increase in agent quota and the addition of background agent functionality, suitable for heavy users who need to operate Comet multiple times a week.
The enterprise plan is priced at 10 times that of the Pro plan. It has unlimited agent tasks, making it suitable for teams that rely heavily on Comet for automating business processes, but is usually more than what individual users need.
Changed from paid (US$200/month) to free in March 2026; Pro/Max differ in daily AI query quota and background assistant features; carries watermark and prompt-injection vulnerability risks, not recommended for banking/sensitive data operations.
