Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier in its niche. The only one that actually gets emotion right.S-tier for teachers. If you teach K-12, start here this week.A-tier. S-tier if you self-host. The reason open-source image gen matters.
