## Why OSGKeyboard

- **Works everywhere** — Messages, Notes, Notion, Cursor, Mail, WeChat — wherever you type
- **Speak, don't edit** — tap (iOS) or hold Option (Mac); AI adds punctuation and structure for you
- **On-device by default** — local recognition on iOS; optional local models on Mac. Cloud upload only when you opt in
- **Bring your own LLM** — built-in polish out of the box, or plug in DeepSeek, OpenAI, Anthropic, OpenRouter, and more
- **Mac global dictation** — menu-bar app, bottom overlay with live feedback, inserts into the frontmost app

---

## Three steps

1. **Install & authorize** — add the iOS keyboard with Full Access; grant mic + Accessibility on Mac
2. **Pick an engine** — local ASR + built-in polish (zero config), or your own API keys
3. **Start talking** — switch to OSGKeyboard, or hold Option on Mac

## Privacy

Speech is transcribed on-device by default. Polish sends **text only** — the transcript and a small amount of nearby cursor text for continuity, never raw audio. Chinese candidate learning stays in the on-device App Group and is not uploaded. Cursor context is not logged or saved to voice history, and secure fields are never captured. See the [Privacy Policy](https://hkgood.github.io/OSGKeyboard/privacy/).

## Build from source

Requires macOS with **Xcode 26** and [XcodeGen](https://github.com/yonaskolb/XcodeGen).

```bash
git clone https://github.com/hkgood/OSGKeyboard.git
cd OSGKeyboard
./Scripts/generate-xcodeproj.sh
open OSGKeyboard.xcodeproj
```

Run tests:

```bash
xcodebuild test -project OSGKeyboard.xcodeproj -scheme OSGKeyboard \
  -destination 'platform=iOS Simulator,name=iPhone 17'
```

## Architecture (brief)

```
OSGKeyboard/          Main iOS app (Flow session host)
OSGKeyboardExt/       Custom keyboard extension
OSGKeyboardMac/       macOS menu-bar app
OSGKeyboardShared/    Shared framework (ASR, LLM, sync, design system)
```

**Flow session model (iOS):** the host app keeps a long-lived audio session; the keyboard sends start/stop signals via App Group; polished text is delivered back for insertion.

**Engine modes:**

- `local` — on-device ASR; built-in polish (or your own LLM key)
- `cloud` — uploads audio to your configured ASR provider, then polishes via LLM

See [CHANGELOG.md](./CHANGELOG.md) for release history and [CONTRIBUTING.md](./CONTRIBUTING.md) for PR guidelines.

## Adding an LLM provider

Append a preset in `OSGKeyboardShared/Models/LLMProvider.swift` — any OpenAI-compatible `/chat/completions` endpoint works out of the box.
