Anecdotally, after the first wave of excitement I don’t know anyone who still uses Bing chat. The value add in chat-augmented search isn’t huge IMO, and forcing the use of Edge doesn’t help.
On the other hand, I am really happy with https://phind.com and find myself using it if I struggle to understand some concept.
For me, the power of the chat based apps is that I can explain my mental model and they can directly build upon that.
