Kai's verdictS-tier all-rounder. If you want one tool that does everything okay-to-great, this is it.S-tier for academic research. Nothing else comes close for systematic reviews.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
