Getting Gemini API Key

To use the AI features of this script, you need a Gemini API key. Follow these steps to obtain your API key:

1. Visit Google AI Studio.
2. Sign in with your Google account.
3. Follow the instructions to generate a new API key.
4. Copy the generated API key for use in the script.

Usage

1. Activate your virtual environment (if using pip) or run poetry shell (if using Poetry).

2. Run the script with the following command:

   python youtube-notes/index.py <YouTube_URL> --gemini-api-key <YOUR_GEMINI_API_KEY> [--copy-to-clipboard]
   

   Replace <YouTube_URL> with the URL of the video you want to generate notes for, and <YOUR_GEMINI_API_KEY> with your actual Gemini API key.

   Use the --copy-to-clipboard flag if you want to copy the generated notes to your clipboard.

3. The script will generate a transcript file, a text file with the notes, and a PDF file with the formatted notes in your Downloads folder.

Environment Variables

You can set the GEMINI_API_KEY environment variable instead of passing it as a command-line argument. Create a .env file in the project root directory with the following content:

GEMINI_API_KEY=your_gemini_api_key_here
