Kai's verdictA-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.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.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.
