Kai's verdict	B-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.	A-tier for ops automation. B-tier for simple copy (use Claude).	S-tier for academic research. Nothing else comes close for systematic reviews.
