Kai's verdictA-tier in its niche. The only one that actually gets emotion right.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.
