YouTube Playlist to Markdown

A powerful Python tool that converts entire YouTube playlists into well-formatted markdown files. Perfect for creating transcripts, documentation, research notes, or archiving video content in a readable format.

Features

• 📋 Batch Processing: Process entire YouTube playlists with a single command
• 🚀 Smart Transcription: Multiple transcription methods with automatic fallback

Transcription Methods

The tool uses a smart multi-method approach:

1. YouTube Transcript API (fastest, no API limits)

   • Fetches existing captions/subtitles
   • No token consumption
   • Works when captions are available

2. Google Gemini API (direct video processing)

   • Processes videos without captions
   • High-quality transcription
   • May have token limits for long videos

3. Audio Download + Gemini (for long videos)

   • Downloads audio first
   • Processes in chunks
   • Handles videos that exceed API limits

Prerequisites

• Python 3.7+
• yt-dlp or youtube-dl command-line tool
• Google Gemini API key

# Process only videos 5-10 from the playlist
python youtube_playlist_to_markdown.py PLAYLIST_URL --start 5 --end 10

# Skip videos that already have output files
python youtube_playlist_to_markdown.py PLAYLIST_URL --skip-existing

# Custom output directory
python youtube_playlist_to_markdown.py PLAYLIST_URL --output-dir my_transcripts

# Add delay between videos (in seconds)
python youtube_playlist_to_markdown.py PLAYLIST_URL --delay 5

# Force a specific transcription method
