NotebookLM is powerful — but your research dies in the browser tab.

Artem Zhutov built a Claude Code skill that fixes that.

> It pulls cited answers out of NotebookLM and drops them into Obsidian as a linked knowledge graph — sources become files, topics become files, citations become wikilinks connecting everything.

> The workflow is dead simple: search YouTube from terminal, add 20 videos as sources to NotebookLM, ask questions, get answers with citations pointing to exactly which video said what. One command can also generate a podcast-style audio overview that syncs to your phone via Obsidian Sync. No more copy-pasting between browser tabs.

> The real trick is what happens in the vault afterward. Open any topic node and you can see which videos mentioned it, what they said, and follow links to the exact passages. Research that used to vanish now lives as markdown you own and can query.

The skill is open source: github.com/ArtemXTech/personal-os-skills
