NotebookLM is strong at questioning sources and weak at keeping the result. For a personal knowledge base, export what you learn to Markdown. NotebookLM Ultra Exporter writes notes, chats and mind maps as Markdown, and can archive a notebook as an Obsidian-style folder with frontmatter and a wiki-link index.

## Quick facts

| Item | Detail |
| --- | --- |
| Stages | Collect sources, work in NotebookLM, export the result |
| Outputs | Vault folder (Obsidian style); Single notes (.md); Outline (.opml); Logseq or Roam pages (.md) |
| Cost to start | Free. Each linked guide states whether its output is Free or Pro. |

## Steps

1. Install [NotebookLM Ultra Exporter](https://chromewebstore.google.com/detail/notebooklm-ultra-exporter/afchokljnhhggkhedfbmkcmdagjmjchj) in desktop Chrome, then refresh any open NotebookLM (Gemini Notebook) tab.
2. Create a notebook for this piece of work and add the sources listed below.
3. Generate and save the answers, reports or Studio items you need.
4. Export each result in the format its destination accepts, then check the file.

## 1. Collect the sources

- Your own notes as sources: [Obsidian vault](https://nlmexporter.com/guides/import/obsidian-vault-to-notebooklm).
- Web reading: [add a web page](https://nlmexporter.com/guides/import/web-page-to-notebooklm).

## 2. Work in NotebookLM

- Save answers worth keeping as notes.
- Ask for atomic notes: one idea, one source, one link.
- Use the [Zettelkasten notes prompt](https://nlmexporter.com/guides/prompts/zettelkasten-notes-prompt).

## 3. Get the result out

| Output and guide | Format |
| --- | --- |
| [Vault folder](https://nlmexporter.com/guides/export/notebook-to-obsidian-vault) | Obsidian style |
| [Single notes](https://nlmexporter.com/guides/export/notes-to-markdown) | .md |
| [Outline](https://nlmexporter.com/guides/export/mind-map-to-opml) | .opml |
| [Logseq or Roam pages](https://nlmexporter.com/guides/integrations/notebooklm-to-logseq) | .md |

> Sync is one-way. Files are written to your folder and never deleted from it; edits in the vault do not flow back to NotebookLM.

## Frequently asked questions

### Can NotebookLM replace Obsidian?

They do different jobs. NotebookLM answers questions about sources; Obsidian stores and links your own notes. Export connects them.

### Can NotebookLM answers be trusted for this?

NotebookLM answers from the sources you give it and cites passages, which makes checking fast, but it can still misread a source. Open the cited passage for anything you will reuse, and keep the export as your record of what was checked.
