NOD is a Chrome extension and web app that summarizes web content with AI and saves it as searchable knowledge — not just bookmarks.

It started as a personal n8n + Gemini + Obsidian automation. People kept asking me to set it up for them, so I turned it into a product anyone can install in 30 seconds.

What it does

• Web articles — Summarize any webpage and extract key insights
• GitHub repos — Analyze project structure and core logic, not just the README
• YouTube videos — Get the key points from hour-long talks without watching them
• Papers & PDFs — Quickly parse arXiv papers and technical documents
• Semantic search — Find saved knowledge by meaning, not just keywords
• Knowledge graph — Visualize connections between saved concepts

Self-hosting

NOD is fully self-hostable. You'll need:

1. A PostgreSQL database with pgvector
