Sayonic

Sayonic is a voice assistant that runs on macOS, enabling users to open apps, find files, add calendar events, and dictate notes through natural speech or text.

Sayonic is a voice assistant that resides as a small, movable interface element on macOS. Users interact by speaking or typing instructions, and the software executes commands such as launching applications, locating local files, managing system settings, or creating calendar events. It offers flexibility by allowing users to choose between built-in AI, their own API keys from various providers, or specific CLI agents. The tool maintains privacy by processing requests locally where possible and only transmitting necessary context to the chosen AI model. It requires macOS 14 Sonoma or later and works on both Apple silicon and Intel Macs.
