A couple of weeks ago, I was scrolling through Reddit when I stumbled across a developer who had built a Chrome extension for my absolute favorite personalized research assistant, NotebookLM. Naturally, I had to give it a try right away. Ever since, I’ve gone all in on exploring how Chrome extensions can improve my NotebookLM workflow, especially the ones built specifically with NotebookLM in mind.
While most Chrome extensions out there are geared toward helping you add sources to your notebooks more quickly, there are also a handful that go beyond that. Other than finding more Chrome extensions for NotebookLM, I've also been pairing the AI tool with some of my productivity tools,NotebookLM Mind Map Extractor like Perplexity, Slack, Notion, Excel, and more. So, naturally, I began wondering if there were Chrome extensions that could make those integrations even smoother. Luckily, I found a couple, and here are the one's that are absolutely worth trying.
Kortex
Pair NotebookLM with any AI tool instantly
KortexA Chrome extension I came across that has quickly become my favorite tool to use when I’m pairing NotebookLM with other AI tools is Kortex. All this extension essentially does is add a button to the UI of the AI tools you likely use every single day like ChatGPT, Gemini, Claude, and Perplexity. As soon as you install this extension, you’ll notice a NotebookLM button at the top-right corner, which blends naturally into the interface. When I first installed the extension, I didn’t use it right away, and when I opened ChatGPT to search for something, I actually thought the button was a new feature for a minute!
The extension’s purpose is ridiculously simple: it lets you instantly add conversation threads into an existing or new NotebookLM notebook with just two clicks. Typically, you’d need to hit CTRL/CMD + A to copy the conversation you’d like to add, then head to NotebookLM, create a new notebook (or open an existing one), and paste it as a source. With this extension though, you can do all of it within the AI tool of your choice without even needing to open NotebookLM.
All you need to do is hit the NotebookLM button that appears and select one of the two options: Create New Notebook or Use Existing Notebook. If you pick the latter, simply choose the notebook you’d like to add the conversation to. That’s it! The conversation will immediately be added, and the NotebookLM notebook with the source included instantly opens up in a new tab.
Before I started using the extension, copy-pasting conversations into NotebookLM didn’t take particularly long. But now that I’ve gotten used to Kortex, I simply can’t imagine going back. It’s made pairing NotebookLM with ChatGPT, Gemini, and Perplexity so much faster and more seamless.
NotebookLM Mind Map Extractor
Use Mind Maps like never before
One of my favorite NotebookLM features is Mind Maps. Though the feature has completely transformed how I study, and I can’t begin to imagine using NotebookLM without it, it still has its flaws. For instance, within NotebookLM, you can only save the Mind Maps you generate as PNGs, which isn’t too helpful. You also have absolutely no control over the final Mind Map that’s generated, and you can’t edit any of the nodes in the diagram or add/remove any of them.
Thankfully, the NotebookLM Mind Map Extractor Chrome extension fixes all of these problems. As the name suggests, it lets you export your Mind Map in different formats. Currently, the extension allows you to export your generated Mind Maps as a FreeMind (.mm) file, OPML (.opml) file, or an XML (.xml) file.
When you’re ready to export a Mind Map, all you need to do is click the extension icon and hit Detect Mind Map. Once it’s detected, select the file format you’d like to export it as, and then click Export Mind Map. Once your diagram is downloaded, you can import it into a mind-mapping software of your choice. Personally, I’ve been uploading mine to Xmind.
Most mind-mapping tools, including Xmind, let you customize your diagrams far beyond NotebookLM’s limitations — you can change node colors, edit existing nodes, add or remove branches, and really make the Mind Map your own. This makes the extension an essential add-on if you rely on NotebookLM’s Mind Maps but don’t want to be boxed in by its current restrictions.
NotebookLM YouTube Link (Source) Automator
Instantly add playlists to your NotebookLM notebooks
I’ve talked about pairing NotebookLM with YouTube plenty of times before. For the most part, I’ve stopped watching YouTube videos and now use NotebookLM to consume them much faster instead. A couple of days ago, I decided to replace my “Watch Later” playlist on YouTube by creating a NotebookLM queue, and it was one of the best changes to my workflow I could’ve made.
But of course, adding each URL as a source manually can get tedious. That’s exactly where the NotebookLM YouTube Link (Source) Automator Chrome extension comes in handy. Whether you’re replicating my exact workflow or just want to add a few YouTube videos to a notebook, the extension lets you instantly add videos in bulk.
When it comes to playlists, you can instantly add the most recent 100 videos you’ve added. To use the extension, simply find the video you want to add, open the extension, and click Add Current Video. Then, open the NotebookLM notebook you’d like to add the video to and click the Add All to NotebookLM button. All your videos will be added automatically within seconds! If it’s a playlist, you’ll see an Extract Playlist button instead. Once the videos are added, just head to the relevant NotebookLM notebook and click Add All to NotebookLM. If you add YouTube videos to NotebookLM often, this extension is one you definitely need to install ASAP!
Download these extensions ASAP
If you’re like me and are obsessed with pairing NotebookLM with other productivity tools, I highly recommend downloading the Chrome extensions above. They’ve helped me save a ton of time and get the most out of NotebookLM every single day.
