Kai's verdictA-tier. S-tier if you self-host. The reason open-source image gen matters.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier. Category-defining UX. If you take notes in meetings, switch this week.A-tier in its niche. The only one that actually gets emotion right.
