Export NotebookLM Conversations to Markdown

NotebookLM's URL import fails on Reddit, X, and anything paywalled. Convert those pages to Markdown first, then upload the clean text as a source.

How to Export

  1. 1Install the Web2MD extension from the Chrome Web Store
  2. 2Open NotebookLM (notebooklm.google.com) and select the conversation to export
  3. 3Click the Web2MD icon, switch to "Export NotebookLM chats" mode
  4. 4Click "Download .md" — multi-turn `## User` / `## Assistant` structure, code blocks, and math are preserved
  5. 5(Optional) Use Queue mode (Pro) to add multiple conversations and merge the entire sidebar into one file

NotebookLM Export Notes

  • •Fixes the "import failed" cases by handing NotebookLM text instead of a URL
  • •Markdown uses far fewer tokens than raw HTML, so each source goes further
  • •Also converts your own NotebookLM notes back out to Markdown

FAQ

Why does NotebookLM fail to import some URLs?

NotebookLM fetches the URL from Google's servers, so it hits the same wall every server-side reader does: Reddit and X block datacenter requests, paywalled articles return the paywall, and JavaScript-heavy pages return an empty shell. The page loads fine in your browser because your session is what those sites are checking for.

How do I add a blocked page as a NotebookLM source?

Open the page in Chrome, convert it with Web2MD, then paste the Markdown into NotebookLM as pasted text rather than a URL. NotebookLM treats it as a normal source and can cite it in answers. This works for Reddit threads, X posts, paid Substack, and internal wikis.

Does Markdown work better than a URL as a NotebookLM source?

For pages NotebookLM can already fetch, a URL is simpler — use it. Markdown wins in two cases: when the fetch fails, and when the page is mostly navigation and ads, since stripping that leaves more of your source budget for actual content.
