A note from the founder
Bring all your work together in your notebooks.
Stop switching between tools and start building momentum with a platform designed for clarity, speed, and intelligence.
"SuperLM didn't start as a grand vision.
It started as a practical solution to a very practical problem: NBLM is good, but it is not enough.
Today, SuperLM is used by thousands of students, production teams, and research labs worldwide.
Why? Because SuperLM stays focused. It does the core job well: notebooks, conversations, research, and action. And it avoids the bloat that slows teams down over time.
If you're done fighting your tools and ready to trust them again, SuperLM is ready for you."

Frequently Asked Questions
Everything you need to know about getting started with SuperLM.
SuperLM is a productivity browser extension that supercharges your Google NotebookLM workflow. It allows you to instantly capture highlighted text, capture page contents, or grab URLs from any browser tab and import them directly into your Google NotebookLM workspace.
Simply select some text on a page, press the Alt+S keyboard shortcut (or right-click and choose the option from the context menu). A fast spotlight finder will display your active notebooks; choose one or type to create a new notebook to save the content instantly.
No. SuperLM operates entirely client-side inside your browser. It doesn't collect, store, or transmit your Google account credentials or your private document sources. It simply bridges content from your active tabs to the NotebookLM application interface.
SuperLM works on all websites. You can capture and import research articles, PDFs, news pages, YouTube transcripts, ChatGPT or Claude conversation threads, Perplexity answers, and social feeds (like X and Reddit).
Yes. We do not operate a backend server to receive, store, or analyze your browsing activity or imported text. All data processing is done locally on your device and transferred directly between tabs, keeping your workspace completely private.
