Project Overview

Autoshow automates the processing of audio and video content from various sources, including YouTube videos, playlists, podcast RSS feeds, and local media files. It performs transcription, summarization, and chapter generation using different language models (LLMs) and transcription services.

The Autoshow workflow includes the following steps:

1. The user provides input (video URL, playlist, RSS feed, or local file).
2. The system downloads the audio (if necessary).
3. Transcription is performed using the selected service.
4. A customizable prompt is inserted containing instructions for the contents of the show notes.
5. The transcript is processed by the chosen LLM to generate show notes based on the selected prompts.
6. Results are saved in markdown format with front matter.

Key Features

• Support for multiple input types (YouTube links, RSS feeds, local video and audio files)
• Integration with various:
  • LLMs (ChatGPT, Claude, Gemini, Cohere, Mistral, Fireworks, Together, Groq)
  • Transcription services (Whisper.cpp, Deepgram, Assembly)
• Local LLM support with Ollama
• Customizable prompts for generating titles, summaries, chapter titles/descriptions, key takeaways, and questions to test comprehension
• Markdown output with metadata and formatted content
• Command-line interface for easy usage
• WIP: Node.js server and React frontend

Setup

scripts/setup.sh checks to ensure a .env file exists, Node dependencies are installed, and the whisper.cpp repository is cloned and built. Run the script with the setup script in package.json.

npm run setup

Run Autoshow Node Scripts

Run on a single YouTube video.

npm run as -- --video "https://www.youtube.com/watch?v=MORMZXEaONk"

Run on a YouTube playlist.

npm run as -- --playlist "https://www.youtube.com/playlist?list=PLCVnrVv4KhXPz0SoAVu8Rc1emAdGPbSbr"

Run on a list of arbitrary URLs.

npm run as -- --urls "content/example-urls.md"

Run on a local audio or video file.

npm run as -- --file "content/audio.mp3"
