How to Save Perplexity Searches to NotebookLM

TL;DR: There's no native way to send a Perplexity thread to NotebookLM. Kaptex adds a one-click "Add to notebook" button directly on Perplexity — the thread, including its citations, lands in your notebook without leaving the tab.

Why Perplexity research threads are easy to lose

Perplexity research rarely happens in one search. You start with a question, get an answer with citations, follow a thread from one of those sources, and then follow another. Ten minutes later you have a chain of searches that together tell a coherent story — with sources attached at every step.

That's the part that's hard to reproduce. The context, the citations, the sequence — it only exists in that thread, in that tab. If you close it or get pulled into something else, it's gone.

Getting it into NotebookLM the manual way means copying the text from each search, switching tabs, finding your notebook, pasting, and figuring out what to do about the source URLs. That's enough friction to make you not bother — and then the research just disappears.

How to save Perplexity searches to NotebookLM

Kaptex adds a floating "Add to notebook" button directly on Perplexity. One click captures the thread and sends it to whichever notebook you have selected in the side panel.

Step 1: Install Kaptex and select your notebook

Install Kaptex from the Chrome Web Store. Click the Kaptex icon in your Chrome toolbar to open the side panel, then pick the notebook you want to save to.

The side panel stays open as you move between tabs, so your notebook selection holds across your entire research session.

Step 2: Run your Perplexity research

Search normally. Follow threads, ask follow-up questions, let the research build. The "Add to notebook" button sits on the page and waits — you don't need to interact with it until you're ready to save.

Step 3: Click "Add to notebook"

When you've reached a point worth keeping, click the button. Kaptex captures the thread — questions, answers, and cited sources — and sends it to your selected notebook as a single source. It shows up in NotebookLM with an auto-generated title.

Step 4: Query it alongside your other sources

Open the notebook. Your Perplexity thread is now a source alongside any PDFs, articles, or other materials you've added. You can ask questions across all of them at once — the citations from Perplexity become part of the broader picture.

Wrap-up

If you use Perplexity for research, saving threads to NotebookLM as you go means you can build on them later instead of starting over. The same one-click workflow works for Claude and ChatGPT — so whichever tool your research takes you to, the path to NotebookLM stays one click away.

You can try it free at kaptex.io — 10 saves per day on the free plan.

Frequently Asked Questions

Does Kaptex capture the cited sources from Perplexity, or just the text?

Kaptex captures the visible content of the page — the questions, answers, and the source references shown in the thread. The source URLs appear in the saved text, so you can still trace back to the originals from inside NotebookLM.

Can I save multiple Perplexity threads to the same notebook?

Yes. Each time you click "Add to notebook," a new source is created in whichever notebook you have selected. You can save as many threads as you like — they all land in the same notebook and can be queried together.

Does the side panel stay open when I switch between tabs?

Yes. The Kaptex side panel stays open and keeps your notebook selection as you move between tabs. If you're switching between Perplexity, a source article, and back again, your target notebook stays set the whole time.

Does this work on Perplexity follow-up questions, not just the first search?

Yes. Kaptex captures the full thread on the page — your original query and any follow-up questions and answers beneath it — as a single source. The more context you build before saving, the more complete the source.
