What is Nyxclaw?
Nyxclaw is a real-time AI avatar companion that gives any Claw-based AI agent a face and voice. It functions as a real-time WebSocket server that bridges the Any Claw companion mobile avatar app (based on Myned's Nyx) with Claw-based AI agents, enabling voice-to-voice conversations with real-time animation and lip-synced video.
The tool is open source and runs on your machine without requiring a GPU. It includes local STT (speech-to-text) and TTS (text-to-speech) pipeline capabilities, making it accessible for users without expensive hardware. The server supports real-time streaming subtitles, rich content cards, and streaming animation for interactive conversations.
Nyxclaw is specifically designed for users of Claw-based AI agents like @openclaw and @zeroclawlabs agents. It provides free mobile apps for both iOS and Android, with the Android app available on Google Play. The companion mobile app allows users to speak to their AI agent, which then responds with the avatar speaking back with real-time animation.
Key features include real-time voice interaction, avatar expressions, automatic lip-syncing, echo cancellation (the avatar won't respond to itself), text chat fallback options, and smart TTS summarization for long responses. The tool supports multi-channel integration and can be self-hosted or forked for customization.
The tool is ideal for developers building AI companion applications, users who want face-to-face interaction with their AI agents, and anyone seeking to add a visual and vocal dimension to text-based AI agents without investing in GPU hardware.
