The YouTube Transcript Summariser is a Chrome extension that extracts transcripts from YouTube videos and generates summaries of varying lengths. Users can choose from three summary lengths: short, medium, and long. The application uses a Flask backend to handle transcript extraction and summary generation, leveraging the YouTube Transcript API and Google's Generative AI model.
- Extracts transcripts from YouTube videos playing currently.
- Generates summaries in three different lengths: short (100 words), medium (500 words), and long (1000 words).
- Handles errors such as invalid YouTube URLs and disabled transcripts.
