Real-time AI video chat that routes through your OpenClaw agent. Uses Groq Whisper (cloud STT),
edge-tts (cloud TTS via Microsoft), and OpenClaw chatCompletions API for conversation. Your agent
sees your camera, hears your voice, and responds with its own personality and memory.
Requires: GROQ_API_KEY for speech recognition. Reads ~/.openclaw/openclaw.json for gateway port and auth token.
Data flows: audio → Groq cloud (STT), TTS text → Microsoft cloud (edge-tts), camera frames (base64) + text
→ OpenClaw gateway → your configured LLM provider (may be cloud — frames leave the machine if using a cloud LLM).
Installs a persistent launchd service (optional). Trigger phrases: "video chat", "voice call",
"call me", "视频一下", "语音", "打电话给我", "我要和你视频", "videochat-withme".
