Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. Best for fast prototypes. Competitive with Lovable — try both.
