# OSGKeyboard

> Free, open-source voice input for iPhone, iPad, and Mac. Speak in any app — polished text lands at the cursor. On-device recognition by default; optional BYOK AI polish.

OSGKeyboard is a custom keyboard (iOS/iPadOS) and menu-bar global dictation app (macOS). Default path keeps audio on-device. Cloud ASR/LLM only when the user opts in and supplies their own keys.
