⚙️ How It Works (Details)

1. URL Input — user pastes any standard YouTube video URL (youtube.com/watch?v=... or youtu.be/...).
2. Video ID Extraction — the app parses the URL to isolate the unique video ID, handling both common YouTube URL formats.
3. Transcript Fetching — calls the YouTube Transcript API to retrieve English captions for that video ID.
4. Text Assembly & Display — individual caption entries are joined into one continuous block of text and displayed in a scrollable text area.

🚀 Getting Started

git clone https://github.com/Cashlin3/youtube-transcript-viewer.git
cd youtube-transcript-viewer
pip install streamlit youtube-transcript-api
streamlit run app.py

⚠️ Limitations

• Only fetches English transcripts — videos without English captions (auto-generated or manual) will return an error
• Videos with captions disabled entirely will show "Transcript not available"
• Timestamps are stripped in the final output — only continuous text is shown

🔮 Future Improvements

• Add multi-language transcript support with a language selector
• Preserve and display timestamps alongside text for easier navigation
• Add a download as .txt / .srt button
• Add AI-powered summarization of the fetched transcript
• Handle YouTube Shorts URLs and playlist links
