I've been using it for about a year now and it's quite capable. Picture search is good and the layout is quite nice.

There have been some fringe topics (mostly programming related) where I needed to resort back to Google because the results were just not good enough. Also it has no Maps equivalent (anymore) which sucks when you want to search for places.

The detection rate is worthless, an algorithm that says anything is Chatgpt would have a detection rate of 100%. What would be more interesting than that is the false positive rate but they never talk about that.
