Turn Any Docs Site into a Single NotebookLM Source in Minutes

Stop adding pages to Google NotebookLM one by one. SiteToMarkdown takes a single URL, crawls all pages under that path, and turns them into one clean Markdown file—perfect for NotebookLM, chatbots, and other LLMs.

Convert a Site to Markdown See how it works

Works great with Google NotebookLM, ChatGPT, and GitHub Copilot.

See how a full-site Markdown export gives NotebookLM the context it needs to answer complex questions correctly.

NotebookLM is powerful. Adding sources one by one isn’t.

If you’re using Google NotebookLM, you already know how powerful it is—once your sources are in.

The problem?

  • Most documentation lives across dozens or hundreds of pages.
  • NotebookLM expects you to add each page as a separate source.
  • Copy‑pasting or manually downloading content is slow, repetitive, and error‑prone.

Instead of focusing on asking smart questions and building AI-powered workflows, you’re stuck doing mindless content wrangling.

You don’t need a new AI tool. You need a better way to feed the one you already love.

Why use SiteToMarkdown?

Google NotebookLM is powerful, but adding sources one by one can be tedious. SiteToMarkdown allows you to convert an entire documentation site into a single Markdown file, which you can then upload as a single source.

It’s built for people who actually use NotebookLM and want to spend time using AI, not preparing data for it.

Meet SiteToMarkdown — your NotebookLM content loader

SiteToMarkdown takes a single seed URL (for example, your docs homepage) and:

  1. Finds all pages under that URL’s path (e.g., everything under /docs/ or /help/).
  2. Retrieves and cleans the content from each page.
  3. Merges it all into one well-structured Markdown file.

You can then upload that Markdown file as a single source to Google NotebookLM, instantly giving your notebook a rich, deeply linked knowledge base.

Built for people who actually use NotebookLM

  • Skip repetitive uploads
    Stop adding pages one at a time. Turn an entire docs site into one uploadable file for NotebookLM.
  • Keep context together
    NotebookLM works best when it can see the full picture. A single Markdown source preserves structure, headings, and relationships across your docs.
  • Perfect for AI chat, agents, and workflows
    A unified Markdown file is not only ideal for NotebookLM, but also for ChatGPT, GitHub Copilot, and other LLMs that accept file-based context.
  • No coding, no scraping scripts
    Just paste a URL, click convert, and download your Markdown. No scripts, crawlers, or dev time required.
  • Great for versioned docs & updates
    Need to update NotebookLM with your latest docs? Re-run SiteToMarkdown, upload the new file, and your notebook is refreshed.

    SiteToMarkdown crawls all pages under that path, extracts the main content, and converts it into Markdown.
  3. Download the generated Markdown file.
    You’ll get a single Markdown file that contains all of your docs content.
  4. Go to Google NotebookLM and create a new notebook.
    Visit Google NotebookLM and create a notebook for your documentation.

    Now NotebookLM can reference your entire documentation site as one cohesive source.

Perfect for power users of NotebookLM

Use SiteToMarkdown + NotebookLM when you want to:

  • Train NotebookLM on your product documentation
    Turn support docs, API docs, or user guides into a single source so NotebookLM can answer customer questions and explain features.
  • Summarize complex technical documentation
    Let NotebookLM digest a whole docs site and give you high-level overviews, explanations, and comparisons.
  • Build internal knowledge assistants
    Combine SiteToMarkdown exports of your wiki, internal handbooks, and SOPs, then use NotebookLM as a smart internal assistant.
  • Research across large public sites
    Convert public documentation, standards, or reference sites into Markdown and let NotebookLM help you research, cross-reference, and synthesize.
  • Create clean, portable knowledge bases for other LLMs
    Use the same Markdown file as context for ChatGPT, GitHub Copilot, and other AI tools—no vendor lock-in.

What a real NotebookLM workflow looks like with SiteToMarkdown

  1. You manage a SaaS product with docs at https://example.com/docs/.
  2. You want NotebookLM to answer questions like “How do I set up SSO?” or “What changed in the latest API version?”
  3. Instead of manually adding dozens of pages to NotebookLM:
    • You paste https://example.com/docs/ into SiteToMarkdown.
    • You wait a bit for the conversion.
    • You download a single Markdown file containing your entire docs site.
  4. You upload that one file to NotebookLM as a source.
  5. Now you can ask:
    • “Explain how authentication works in our API to a non-technical stakeholder.”
    • “Summarize the setup steps for our webhooks.”
    • “What breaking changes are in the latest release?”

Why not just copy-paste into NotebookLM?

Manual approach

  • Add URLs or files one by one.

You can treat the exported Markdown as your portable knowledge asset, across tools and platforms.

FAQ

Does SiteToMarkdown work only with NotebookLM?

No. SiteToMarkdown generates a Markdown file, which you can use with Google NotebookLM, ChatGPT, GitHub Copilot, or any other LLM that supports file uploads or text context. This page focuses on NotebookLM use, but the file is fully reusable.

What kind of URLs work best?

Any documentation-style site where relevant content lives under a common path, such as:

  • https://yourapp.com/docs/
  • https://yourcompany.com/help/
  • https://domain.com/knowledge-base/

SiteToMarkdown will retrieve pages under that path and merge their content.

Will it include navigation, headers, or ads?

SiteToMarkdown is designed to focus on the main page content. While exact results can vary by site, the goal is to produce clean, readable Markdown that’s useful as LLM context—not a messy HTML dump.

How big can the Markdown file be for NotebookLM?

NotebookLM supports sizable sources, but you’ll still be limited by its own file size and token limits. For very large sites, you might choose to:

  • Export per section (e.g., /docs/api/, /docs/user-guides/).
  • Create multiple Markdown files and upload each as its own source.

Do I need to install anything?

No. SiteToMarkdown is a web-based tool. Just visit the site, enter your URL, and download the Markdown file—no installs, no scripts.

Can I update my NotebookLM source when docs change?

Yes. Simply re-run the same URL in SiteToMarkdown, download the new Markdown file, and upload it to your NotebookLM notebook. It’s an easy way to keep your AI assistant in sync with your latest documentation.
