+# AI Video Transcriber & Translator
+
+This tool extracts audio from videos, transcribes it using OpenAI's Whisper model, and translates the transcript using Google's Gemini API.
+
+## Setup
+
+1.  **Install Dependencies:**
+    ```bash
+    pip install -r requirements.txt
+    ```
+    *Note: You need `ffmpeg` installed on your system.*
+
+2.  **API Key:**
+    Set your Gemini API key as an environment variable:
+    ```bash
+    export GEMINI_API_KEY="your_api_key_here"
+    ```
+
+## Usage
+
+### Quick Start (Wizard)
+For a user-friendly, interactive experience, run the wizard script in the root directory:
+
+```bash
+./run_wizard.py
+```
+This will guide you through selecting files, languages, and enabling features like cleanup and embedding.
+
+### Advanced (CLI)
+Run the `main.py` script directly:
+
+```bash
+python ai_transcriber/main.py <path_to_video_or_folder> [options]
+```
+
+### Options:
+*   `--model`: Whisper model size (`tiny`, `base`, `small`, `medium`, `large`). Default: `base`.
+*   `--lang`: Target language for translation. Default: `English`.
+*   `--force`: Overwrite existing transcript/translation files.
+
+### Examples:
+
+**Single File:**
+```bash
+python main.py ../my_video.mp4
+```
+
+**Entire Directory (Recursive):**
+```bash
+python main.py ../videos_folder/ --lang "Spanish" --model small
+```
