Comet
Productivity · freemium
Pros
- ✓Assistant operates on the page you are already viewing instead of in a separate window with no context
- ✓Chromium base keeps most Chrome extensions working, which removes the usual dealbreaker when switching browsers
- ✓Import carries bookmarks, passwords, cookies, history and extensions across in one step
- ✓Free to download with no subscription required to start using it
- ✓Background Assistants give paying users parallel agentic tasks with confirmations gathered in one place
Cons
- ×Browser-agent limits are published only as relative claims, so no tier states how many agent queries you actually get
- ×The features most people want the browser for, Background Assistants and Email Assistant, sit behind the $200/mo Max tier
- ×Switching browsers is a bigger commitment than installing an extension, and profile migration is never fully clean
- ×An assistant with access to your logged-in sessions is a meaningful trust decision that a chat window in another tab does not require
