Kai's verdictA-tier for social/casual. B-tier for serious work. Good entry point.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for open-source model APIs. The default in this space.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
