Picovoice builds an end-to-end voice AI platform that processes audio entirely on-device. Its engines include Porcupine for custom wake words, Rhino for speech-to-intent, Cobra for voice activity detection, Cheetah for streaming speech-to-text, and Leopard for batch transcription. Developers customize models in the browser-based Picovoice Console without ML expertise and deploy across microcontrollers, Raspberry Pi, Android, iOS, web, Linux, macOS, and Windows. The company positions on-device processing as private by design, with no cloud dependency at runtime.
