About

Subtle (formerly Skywalk, Inc., d/b/a Subtle Computing) builds Voicebuds, a voice-first computing device and software platform that lets users dictate, chat with AI, and control devices via speech so quiet it can't be heard by others nearby. The company's voice isolation technology captures near-silent speech in noisy environments like open offices, cafes, and transit, filtering out ambient noise to make voice input viable anywhere. Subtle combines custom hardware, software, and machine learning models purpose-built for private, always-available voice productivity.
