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 in its niche. The only one that actually gets emotion right.A-tier. Bet on this one — the Sparkpage format is genuinely new.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
