I love Arc. I tried Dia. I wanted to like it but don't see how it's going to be valuable for me.

The browser features are _much_ worse than Arc (no sidebar, bookmarks are a dropdown, ...) and most of the time the AI can't even "see" or "read" what's on the page I'm viewing, so it's just worse than using Claude/ChatGPT/Gemini.

I'm still using Arc and will probably continue until there's another browser that copies its UI/UX improvements.
