Kai's verdict	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.	S-tier for text-in-image. Use this for posters, Midjourney for art.	A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.
