Useful Sensors

Useful Sensors, now operating as Moonshine AI, builds fast, low-resource, private-by-design AI that runs entirely on-device. Founded by former Google TensorFlow leads Pete Warden (CEO) and Manjunath Kudlur (CTO), the company started with plug-and-play hardware like the Person Sensor and Tiny Code Reader and now ships Moonshine, an MIT-licensed family of low-latency speech-to-text, text-to-speech, and intent-recognition models with SDKs for in-browser JavaScript, server-side Python, and C++ on edge devices. There is no hosted cloud API — all speech processing happens locally on the device.

Useful Sensors is profiled on the APIs.io network. Tagged areas include Company, Ai Ml, Speech To Text, Text To Speech, and Voice.

Useful Sensors’ developer surface includes documentation, getting-started guide, support, CLI, changelog, and 8 more developer resources.
