Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
