Kai's verdict	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	A-tier in its niche. The only one that actually gets emotion right.	S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.	S-tier infrastructure. The one platform every AI dev eventually uses.
