Strengths	Open-weight model available Great for loops + game audio + SFX Commercial-use clarity	Ships working React + Tailwind code Shadcn/ui native One-click deploy to Vercel	Runs locally, edits your actual files Strong on large codebases with 1M context Great at multi-step tasks	Detects + mirrors emotional tone EVI (Empathic Voice Interface) feels different Expressive voice output
Weaknesses	Not for full songs with vocals Shorter generation limits	Best for shadcn stack Iterating can be fiddly	Terminal-based — learning curve Can't be used without Claude subscription	Niche use case Pricing ramps fast
Kai's verdict	A-tier for its niche. Different use case than Suno — SFX and loops, not songs.	S-tier. If you're on Vercel/shadcn, this is cheating.	S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.	A-tier in its niche. The only one that actually gets emotion right.
