@Vivaldi I don't even understand the difference.
In Vivaldi you can pin ai assistant of your choosing to the sidebar if you want to. On those innovative AI browsers you have... AI assistant in the side bar. It's basically it. Maybe sometimes there are some additional features like AI naming tab groups, but that's just sprinkle on the top.
Edge has AI in the sidebar, Opera has AI in the sidebar, Firefox has AI in the sidebar. How is it different than adding AI in the Vivaldi sidebar? Maybe someone could enlighten me.
