Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.A-tier for creators training custom looks. B-tier for general use.A-tier in its niche. The only one that actually gets emotion right.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
