- What they did
- In the thread, the poster says Comet’s browser agent handled a few concrete chores for them: summarizing tabs, finding a Reddit comment they had made a few days earlier, marking Gmail messages as read, and unsubscribing from newsletters. In follow-up comments they say Comet appears to work through a visible browser agent that thinks, clicks in a virtual browser, and can carry out tasks in the background, while the person gives the prompts and watches or redirects it.
- How it went
- The reported result is simply that these tasks worked well enough that the poster decided to stick with Comet over Dia and Arc. They also note Comet is slow or laggy, and another commenter says the agentic features often misread sites or need intervention.
- Worth knowing
- One practical catch mentioned in the thread is cost: the poster says they were using Comet without paying because it gives a few free requests per day.
