Your AI VTuber co-host that actually pays attention. Watches your screen, hears your audio, reads your stream chat, and reacts with 84 animations. Custom VRM avatars. Full VTuber face rig. Fully offline capable. No API keys required.
The developer filed this on the Steam store page. It is not a guess by active.games.
Vtuber Assistant uses generative AI to create live text responses and voice output as a customizable co-host companion. It reacts to your voice/text input, screen audio/visuals, and Twitch chat with fun, contextual commentary. All core functionality runs through a secure built-in proxy by default (Grok + ElevenLabs integration) — no external API keys or setup required to use the app. Free limited daily uses are included. Optional premium features (unlimited generations, premium voices) are handled via Steam microtransactions (AI Credits packs). Local fallback models (bundled SmolLM2 + Piper TTS) provide offline functionality when needed. Twitch chat integration is read-only — the AI consumes incoming messages and produces in-app responses only. All outputs are moderated by a built-in Safety Guard to help prevent inappropriate content.
