Pricing	Free (limited) + $10/mo Pro + $19/mo Business	Free + $20/mo	Voice included with ChatGPT Plus; Realtime API by usage	Free trial + paid plans
Best for	Teams with GitHub already. Devs who don't want to change IDEs.	Frontend devs, PMs prototyping UIs, anyone on Next.js.	Voice chat users, developers building voice agents on OpenAI.	Designers brainstorming first drafts.
Strengths	Great enterprise story Works in your existing IDE Chat + autocomplete	Ships working React + Tailwind code Shadcn/ui native One-click deploy to Vercel	Advanced Voice Mode feels genuinely conversational Realtime API enables true two-way voice apps Built into ChatGPT	Prompt-to-UI with real layouts Exports to Figma Faster than hand-designing from scratch
Weaknesses	Less agentic than Cursor/Claude Code Model quality varies	Best for shadcn stack Iterating can be fiddly	Pricey for production apps Less voice variety than ElevenLabs Platform lock-in	Output needs designer polish Pricing unclear / changes often
Kai's verdict	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	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. Useful for first drafts. v0 is the better bet for shipping code.
