What is Kaptex?

Kaptex is a Chrome extension that lets you save content to NotebookLM from any tab in one click.

How do I install Kaptex?

Install the Chrome extension from the Chrome Web Store in seconds — no account required to get started.

Which sites does Kaptex support?

Kaptex works on Claude, ChatGPT, Perplexity, YouTube, Reddit, and any URL — plus file uploads.

Can I save my Claude, ChatGPT, or Perplexity conversations to NotebookLM?

Yes. Kaptex injects a one-click button on Claude, ChatGPT, and Perplexity that captures the full conversation as a text source — not a URL.

Can Kaptex save Reddit threads to NotebookLM?

Yes — and Kaptex formats the post and top comments into clean Markdown so NotebookLM actually processes it correctly, unlike saving the URL directly.

Can I add multiple URLs to NotebookLM at once?

Yes. Paste a list of URLs one per line and Kaptex adds them all in sequence. Or sweep all open browser tabs into a notebook at once.

Is Kaptex safe? What data does it access?

Kaptex only reads content when you explicitly click the capture button. No background scraping, no browsing history collected.

How is Kaptex different from NotebookLM Web Importer?

Web Importer handles URLs and YouTube well. Kaptex adds one-click capture on Claude, ChatGPT, and Perplexity, structured Reddit threads, file uploads, and browser tab sweep.

Will Google just add these features to NotebookLM natively?

Maybe, over time. But some of what Kaptex does — like capturing private Claude and ChatGPT conversations — Google can't build natively. And the friction you're experiencing today is real.
