Similar space — we built ClawWatch, which runs an OpenClaw agent natively on Galaxy Watch with offline speech recognition (Vosk) and TTS. Instead of streaming to ChatGPT directly, it connects through an OpenClaw gateway so the watch agent can participate in multi-agent rooms and maintain persistent memory across sessions.
The offline STT means it works without a phone connection for voice capture, though it still needs network for LLM inference.
