Comet Browser vs Sidekick Browser

You get a glimpse of what an AI-native, purpose-driven browser can feel like with Comet, especially if you're the kind of power user who wants an assistant that clicks around the web for you and pulls in email or calendar context. The interface is built to showcase these agentic features in a way that feels more user-friendly than most early AI browsers.

But the experience is rough around the edges. You run into moments where the assistant can't actually take action on the page you're on, even though the demos suggest it should. The workflow sometimes breaks down when you expect the assistant to handle something and it just can't, so you're still jumping in to finish the job yourself.

If you're an early adopter who likes trying new things and doesn't mind dealing with unfinished features, you'll appreciate what's here. For anyone expecting a polished, efficient user experience that just works, you're going to feel the inconsistency and friction.
