+# WhisperDictate
+
+A simple macOS menu bar app for voice dictation using OpenAI Whisper (local, offline).
+
+## Features
+
+- 🎤 Global hotkey (⌃⌥D) to start/stop recording
+- 🔒 Fully offline - uses local Whisper model
+- ⚡ Automatic paste into any app
+- 🇭🇺 Hungarian language support (configurable)
+
+## Requirements
+
+- macOS 13.0+
+- Apple Silicon Mac (M1/M2/M3)
+- whisper-cpp (`brew install whisper-cpp`)
+- Whisper model file
+
+## Installation
+
+### 1. Install whisper-cpp
+
+```bash
+brew install whisper-cpp sox
+```
+
+### 2. Download Whisper model
+
+```bash
+mkdir -p ~/.whisper-models
+curl -L -o ~/.whisper-models/ggml-medium.bin \
+  "https://huggingface.co/ggerganov/whisper.cpp/resolve/main/ggml-medium.bin"
+```
+
+### 3. Build WhisperDictate
+
+```bash
+git clone https://github.com/YourUsername/WhisperDictate.git
+cd WhisperDictate
+swiftc -o WhisperDictate main.swift \
+    -framework Cocoa \
+    -framework AVFoundation \
+    -framework Carbon \
+    -framework CoreGraphics
+```
+
+### 4. Run
+
+```bash
+./WhisperDictate
+```
+
+Or copy to your bin folder:
+
+```bash
+cp WhisperDictate ~/bin/
+~/bin/WhisperDictate &
+```
+
+## Usage
+
+1. Look for the 🎤 icon in your menu bar
+2. Press **⌃⌥D** (Control + Option + D) to start recording
+3. Speak (icon changes to 🔴)
+4. Press **⌃⌥D** again to stop and transcribe
+5. Text is automatically pasted where your cursor is
+
+## Audio Feedback
+
+- 🔔 **Tink** - Recording started
+- 🔔 **Pop** - Recording stopped, processing
+- 🔔 **Glass** - Success, text pasted
+- 🔔 **Basso** - Error
+
+## Permissions
+
+The app needs:
+- **Microphone** access (System Settings → Privacy & Security → Microphone)
+- **Accessibility** access for auto-paste (System Settings → Privacy & Security → Accessibility)
+
+## Configuration
+
+Edit `main.swift` to change:
+- Language: Change `"-l", "hu"` to your language code (e.g., `"en"`, `"de"`)
+- Hotkey: Modify `registerHotkey()` function
+- Model: Change `whisperModel` path for different model sizes
