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.A-tier. S-tier if you self-host. The reason open-source image gen matters.S-tier for open-source model APIs. The default in this space.
