Strengths	Very strong motion + physics Often beats Runway on realism Great price	Up to 20-sec clips at 1080p Strong physics + scene composition Storyboard feature for longer narratives Remix existing videos	Great enterprise story Works in your existing IDE Chat + autocomplete	Production-grade agent primitives Built on Claude (best reasoning) Full control — build exactly what you need
Weaknesses	UX is rough for English speakers Queue times	Stricter content policy than competitors Hit-or-miss on complex motion Text-in-video still struggles	Less agentic than Cursor/Claude Code Model quality varies	Developer-only You build the UI
Kai's verdict	A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.	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.	S-tier for builders. The right primitives. What Kai is built on under the hood.
