Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-tier in its niche. The only one that actually gets emotion right.B-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.
