How to Save ChatGPT Conversations to NotebookLM

TL;DR: Pasting a ChatGPT link into NotebookLM doesn't give you the conversation content. Kaptex adds a one-click "Add to notebook" button on the ChatGPT page that captures the full text and sends it to your notebook directly.

Why pasting a ChatGPT link into NotebookLM doesn't work

You've been in ChatGPT for 45 minutes building a research framework. You want it in NotebookLM so you can query it alongside your other sources. You copy the shared link and paste it into NotebookLM's URL input — and nothing useful comes back.

ChatGPT shared links exist, but when NotebookLM tries to fetch them, it doesn't get the actual conversation text. The link opens an interface page, and that page doesn't expose your conversation in a way NotebookLM can read. The content exists — there's just no direct path from ChatGPT to NotebookLM.

How to save a ChatGPT conversation to NotebookLM

Kaptex injects an "Add to notebook" button directly on the ChatGPT page. One click captures the full conversation text and sends it to the right notebook.

Step 1: Install Kaptex and select your notebook

Install Kaptex from the Chrome Web Store and open the side panel by clicking the icon in your browser toolbar.

Select the NotebookLM notebook you want to save to.

The side panel stays open as you move between tabs — you set your notebook once and it stays selected.

Step 2: Go to your ChatGPT conversation

Navigate to any ChatGPT conversation — one you're still working in or one from earlier. The Kaptex "Add to notebook" button appears on the page automatically.

Step 3: Click "Add to notebook"

Kaptex captures the full conversation text directly from the page and sends it to your selected notebook. No copy-pasting, no tab switching.

Step 4: Open NotebookLM and start querying

Your conversation appears in the notebook as a source with a generated title — the complete exchange, not a URL reference. You can query it alongside your other sources right away.

Wrap-up

Once the conversation is in NotebookLM, you can ask questions across it alongside everything else in your notebook — documents, articles, other conversations. This same workflow works for Claude and Perplexity too, so whichever AI tool you're using for research, the path to NotebookLM is one click away.

Frequently Asked Questions

Why doesn't pasting a ChatGPT link into NotebookLM work?

ChatGPT shared links open an interface page, not a plain document. When NotebookLM fetches that URL, it gets the page structure back — not the conversation text. Kaptex bypasses this by reading the content directly from the page you're on.

Does Kaptex save both my messages and ChatGPT's responses?

Yes. The full conversation — your prompts and all of ChatGPT's replies — is captured as a single source in your notebook.

Can I save a conversation that's still in progress?

Yes. Kaptex captures whatever is on the page at the moment you click. You can save partway through and save again at the end — each save creates a separate source in your notebook.

What does the source look like in NotebookLM?

It shows up as a text source with an auto-generated title. The full conversation text is readable and queryable — NotebookLM treats it the same as any other document you've added.

Does this work with GPT-4o and other ChatGPT models?

Yes. Kaptex captures whatever is in the conversation window regardless of which model was used. The model version doesn't affect how the text is captured.
