Weaknesses	Best for shadcn stack Iterating can be fiddly	Pricey for production apps Less voice variety than ElevenLabs Platform lock-in	Less agentic than Cursor/Claude Code Model quality varies	Output needs designer polish Pricing unclear / changes often
Kai's verdict	S-tier. If you're on Vercel/shadcn, this is cheating.	S-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement.	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	B-tier. Useful for first drafts. v0 is the better bet for shipping code.
