ytrag 2.3.0

YouTube transcripts to RAG-ready volumes

ytrag

YouTube transcripts → RAG-ready volumes.

Download YouTube subtitles and consolidate them into LLM-ready volumes.

Quick Start

# Install from PyPI
pipx install ytrag

# Download and process a YouTube channel
ytrag all "https://youtube.com/@ChannelName"

That's it! The transcripts will be cleaned and organized into volumes ready for use with LLMs.

pipx install ytrag

With pip

pip install ytrag

ytrag all "https://www.youtube.com/playlist?list=PLxxxxxxx"

Options

# Specify languages (default: auto-detect from video)
ytrag all "https://..." --lang es,en,pt

# Custom output directory
ytrag all "https://..." --output ./my-transcripts

# Target a source limit for NotebookLM (default: 50, Plus can use 100)
ytrag all "https://..." --target-volumes 100

# Advanced override: fixed transcripts per volume
ytrag all "https://..." --per-volume 50

# Prefer a language for download and deduplication
ytrag all "https://..." --lang es

# Rebuild outputs from an existing folder of .vtt subtitle files
ytrag rebuild "./ChannelName" "Channel Name" --target-volumes 100

# Slow down large channel downloads to avoid YouTube rate limits
ytrag all "https://..." --sleep-interval 15 --max-sleep-interval 30

# Check status of current directory
ytrag status

# Show version
ytrag --version

Output Structure

After running ytrag all, your directory will look like:

./
└── ytrag-ChannelName/
    ├── raw-subtitles/             # Downloaded .vtt subtitle files
    ├── clean-transcripts/         # One cleaned .md transcript per video
    ├── rag-volumes/               # NotebookLM/RAG-ready volumes only
    │   ├── ChannelName_Vol01.txt
    │   └── ChannelName_Vol02.txt
    ├── manifest.json              # Metadata
    └── .ytrag_archive             # Resume tracking

Each volume contains cleaned, consolidated transcripts ready for use with LLMs and RAG systems.

raw-subtitles/ is only created when --keep-raw is used. By default ytrag keeps the cleaned transcripts and RAG-ready volumes.

Features

• Simple: One command does everything
• Auto language detection: Defaults to video's original language
• Resume support: Re-run to continue where you left off
• Clear progress: Shows current/total videos and ETA while downloading large channels
• Accurate channel counts: Channel root URLs automatically target the Videos tab
• NotebookLM-friendly volumes: Smaller default volumes and a dedicated rag-volumes folder
• Citable source markers: Repeats video/date markers throughout transcripts so NotebookLM hovers show useful context
• Language-aware deduplication: Honors --lang, otherwise prefers the majority subtitle language
• Smart deduplication: Skips regional variants (en-US if en exists)
• Adaptive rate limiting: Automatically handles YouTube rate limits
• Clean output: No intermediate files, just the volumes you need

Requirements

• Python 3.10+

Troubleshooting

"No subtitles found"

Some videos don't have subtitles enabled. Try:

• Using --lang with different language codes
• Auto-generated subtitles are downloaded by default

Rate limiting errors

YouTube may rate-limit large channel downloads. ytrag uses conservative delays by default and retries extractor failures with exponential backoff. If YouTube still rate-limits the session, failed videos are not added to .ytrag_archive; run the same command again later and ytrag will retry the missing videos.

Useful controls:

ytrag all "https://..." \
  --sleep-interval 15 \
  --max-sleep-interval 30 \
  --stop-after-errors 3
