I'm very mildly pro-AI, in the sense that I remain optimistic there will be at least a few cool use cases and I'd love to find them.
So I tried Dia... And uninstalled it a few hours later. Why would I want to "chat with my tabs"? Even if I didn't think this was a rubbish use case, every browser comes with a chatbot sidebar/extension/whatever, why would I want to change browsers just for that?
Heavy pass. Also, after how they abandoned Arc, I don't think they can be trusted to develop a product and not pull the rug from under the users when it becomes mildly inconvenient to keep working on it.
The best thing The Browser Company ever did was unintentionally making someone else decide to create Zen.
