YouTube Watch History Summarizer

This program fetches your YouTube watch history for the past week, retrieves video transcripts and descriptions, and generates AI-powered summaries with key points and learnings for each video.

Setup

python3 -m venv .venv
source .venv/bin/activate
pip install --upgrade pip
pip install -r requirements.txt -U

2. Set up YouTube API credentials:

   • Go to the Google Cloud Console
   • Create a new project or select an existing one
   • Enable the YouTube Data API v3
   • Create OAuth 2.0 credentials (Desktop application)
   • Download the client configuration file and save it as client_secrets.json in the project directory

3. Create a .env.local file with your API keys:

YOUTUBE_API_KEY=your_youtube_api_key
OPENAI_API_KEY=your_openai_api_key

Usage

Run the program:

python app.py

The program will:

1. Authenticate with YouTube (first time will open a browser for OAuth)
2. Fetch your watch history for the past 7 days
3. Get transcripts and descriptions for each video
4. Generate summaries using OpenAI's GPT-4
5. Save results to a JSON file named youtube_summaries_YYYYMMDD.json

The output JSON will contain:

• Video details (ID, title, author, watch date)
• Summary of the video content
• Key points discussed
• Main learnings from the video

Notes

• The program requires YouTube OAuth authentication to access your watch history
• Video transcripts are retrieved when available; otherwise, video descriptions are used
• Summaries are generated using OpenAI's GPT-4 model
• Results are saved in JSON format for easy parsing and integration with other tools
