Kai's verdictA-tier for real-time. B-tier for everything else. Worth checking when news breaks.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.A-tier in its niche. The only one that actually gets emotion right.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
