name: youtube-summarizer description: Build and use a YouTube tool similar to NoteGPT.io — paste link → get transcript + rich AI summary + timestamped notes + key points. Support fallback transcription for videos without subtitles.

YouTube Summarizer (NoteGPT Style)

Goal

Create a personal/local version that mimics NoteGPT:

• Paste YouTube link
• Auto-fetch transcript (with timestamps)
• Generate clean, detailed content-rich summary
• Produce structured AI Notes / Study Notes
• Support videos without subtitles (via Whisper fallback)
• Output: Summary, Full Transcript, Key Points, Chapters

Desired Output Format (NoteGPT-like)

1. Video Title & Metadata
2. Concise Summary (TL;DR)
3. Detailed Content-Rich Notes (your preferred direct style — "The second subtype of basic research is...")
4. Timestamped Key Points / Chapters
5. Full Transcript (with timestamps, collapsible if web UI)

Core Features to Implement

• Transcript extraction (youtube-transcript-api)
• Fallback: yt-dlp + whisper (for no-subtitle videos)
• LLM-powered summarization (Grok, OpenAI, Gemini, Claude, or local)
• Structured outputs: Summary, Mind-map style bullets, Study notes
• Optional: Batch processing, Export (Markdown, PDF, DOCX)

Updated Rules for Summaries

• Direct content style (exactly as you showed earlier)
• Keep speaker's examples, flow, and explanations intact
• Avoid "The video says..." — just explain the concepts

Helper Scripts (in Sandbox)

I’ve prepared the foundation scripts for you.

Would you like me to:

1. Show the full improved Python script (CLI + basic web version)?
2. Add Streamlit web UI (paste link → beautiful output like NoteGPT)?
3. Include Whisper fallback for no-caption videos?
4. Add export to Markdown/PDF?

Just tell me your preference (e.g., "Give me the Streamlit version" or "Add Whisper support"), and I’ll generate the complete code right away.

Paste a YouTube link now if you want to test the current version!
