Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for teachers. If you teach K-12, start here this week.S-tier for local inference. If you care about privacy or want to tinker, install this today.A-tier. Close second to Cursor. If $5/mo matters, start here.
