Kai's verdict	S-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.	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	A-tier for real-time. B-tier for everything else. Worth checking when news breaks.
