Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier for social/casual. B-tier for serious work. Good entry point.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier for study. The Audio Overview is a killer feature.
