YouTube Timestamp Generator (Streamlit)

Paste a YouTube URL (or video id) and generate chapter-like timestamps from the video's transcript.

What it does

• Fetches available transcripts (when the creator has transcripts enabled)
• Lets you pick the transcript language
• Chunks the transcript into time-based sections
• Generates a simple chapter title for each chunk (TF‑IDF keywords for English; otherwise first-sentence fallback)
• Outputs copy/paste-friendly timestamps (great for YouTube descriptions)

Setup

cd /Users/kenguyen/youtube_timestamps_streamlit
python -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt

Run

cd /Users/kenguyen/youtube_timestamps_streamlit
source .venv/bin/activate
streamlit run app.py

Notes / limitations

• Some videos do not expose transcripts (disabled, unavailable, or region/age restricted).
• This generates suggested chapters. For higher-quality titles you’d typically use an LLM, but this project intentionally avoids paid APIs.
