# 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!
