shinshin86/aituber-onair — reverse-engineered prompt

Build me a working AI VTuber starter app using AITuber OnAir. I want a local web app where I can open it in the browser, pick or use a starter avatar, type chat messages, and have the character answer back with voice and mouth movement.

Please make it feel stream ready, with a simple settings screen where I can add my AI and text to speech API keys, choose the provider, edit the character personality, and test the voice. Start with the PNGTuber or VRM template, whichever is easiest to get running cleanly, but keep the code organized so I can swap the avatar later.

I’d also like it to be able to react to viewer comments eventually, so include the right AITuber OnAir pieces for chat, voice, memory, and comment handling if they fit. Make sure it runs locally with npm run dev and include clear setup notes. Look up the current AITuber OnAir docs online if you need to.
