The features are the pipeline.

Each capability exists to make voice input feel immediate, accurate, and native to the app you are already using.

  • Screen context OCR

    Reads what is on your screen to understand nearby names, project terms, and homophones in real time.

  • Voice command mode

    Use voice to control, edit, summarize, translate, or reply without switching apps or context.

  • Local and remote models

    Run fully on-device for privacy, or use remote LLM providers when that is the right tradeoff.

  • Bilingual UI

    Switch the interface language between English and Simplified Chinese instantly.

Private by default. Local when you want it.

Questions, answered.

What is OpenType?

OpenType is a native macOS menu bar app that turns your voice into polished text in any app. Hold a hotkey, speak, and the transcribed, cleaned-up text is typed directly at your cursor.

Does OpenType work offline?

Yes. With WhisperKit or Apple Speech plus a local MLX model such as Qwen3, OpenType can transcribe and refine text entirely on-device. Remote LLM providers are optional.

Which macOS version and hardware does OpenType require?

macOS 26 or later on Apple Silicon. Intel Macs are not supported.

How is OpenType different from Apple's built-in dictation?

OpenType adds LLM cleanup, screen context via OCR, voice command mode, and global hotkey insertion into any app without switching context.

Which apps does OpenType work in?

Any macOS app that accepts text input. OpenType uses the Accessibility API to insert text at your cursor, with a clipboard-paste fallback.

Is OpenType free and open source?

Yes. OpenType is MIT-licensed and the full source is on GitHub. Prebuilt binaries are published on GitHub Releases.

Which languages does OpenType support?

Speech recognition supports many languages via WhisperKit and Apple Speech. The app UI is bilingual in English and Simplified Chinese.

How does screen context help dictation?

OpenType can capture on-screen text with ScreenCaptureKit and Vision, then feed it to the LLM so it picks the right word based on what you are looking at.
