What This Actually Is
Two pieces, one combo.
NotebookLM is Google's free research tool. You feed it sources (PDFs, Google Docs, websites, YouTube videos, your own notes) and it becomes an expert on exactly that material. It reads up to a million words at once, answers only from what you gave it, and cites where every answer came from. It also spits out summaries, study guides, mind maps, even podcasts. It is genuinely one of the best research tools on the internet right now, and it costs nothing.
The NotebookLM skill is a free, open-source plugin (built by a developer who goes by PleasePrompto, ~7,000 GitHub stars) that connects NotebookLM directly to Claude. Once it's installed, you just talk to Claude normally and it goes and asks NotebookLM for you, then uses the answer to help with whatever you're doing.
Put them together and Claude stops guessing. It pulls grounded, cited answers from your own documents instead of making things up.
Section 2
Why The Combo Is So Powerful
It frees the knowledge that gets trapped
NotebookLM has no public API, so normally everything you put into it is stuck behind the browser. You have to go there, ask, copy the answer, paste it back into Claude. This skill kills that copy-paste dance. Claude reaches into NotebookLM and pulls answers out automatically.
The heavy lifting is free
This is the part that breaks people's brains. The actual analysis happens on Google's servers, and Google pays for it. Claude only spends a tiny bit of usage sending the question and bringing the answer back. So you get a full research engine bolted onto Claude without watching your usage disappear.
Answers are grounded, so Claude stops hallucinating
NotebookLM answers only from the sources you uploaded, and every answer carries a citation. When Claude builds on those answers, it's building on your real documents, not a plausible-sounding guess. For research, manuals, legal docs, or anything where being wrong matters, this is the whole game.

What You Need First
One honest heads-up so you don't hit a wall: this particular skill runs in Claude Code, the version of Claude that lives on your computer. It does not work in the regular web app, because it needs to open a real browser to talk to NotebookLM, and the web app won't allow that.
Good news: Claude Code is free, and you do not need to know how to code to use it. If you've never set it up, it takes about two minutes. I wrote the full walkthrough here:
New to Claude Code?
Start with Claude Code Day One. Get it running first, then come back here. You'll also want a free Google account for NotebookLM (a dedicated one is smart, more on that at the end).
Just want persistent chat sessions or to use this inside Cursor or Codex instead? The same developer makes an MCP-server version. I covered that one in the NotebookLM MCP guide. For most people, this skill is the simpler path. Keep reading.
Section 4
Install It (5 Minutes, No Code)
You have two ways to do this. Pick one.
Path A — Let Claude install it for you (easiest)
Open Claude Code and paste this. It downloads the skill into the right folder and confirms it's ready. This is the no-terminal-thinking-required path.
Paste into Claude Code
Install the NotebookLM skill for me. Create the folder ~/.claude/skills if it doesn't exist, then clone https://github.com/PleasePrompto/notebooklm-skill into it as a folder named "notebooklm". When you're done, list my skills so I can confirm it's there.Path B — Run it yourself (one paste)
Prefer to do it directly? Open your terminal and paste this. Three lines, runs in seconds.
Run in your terminal
mkdir -p ~/.claude/skills
cd ~/.claude/skills
git clone https://github.com/PleasePrompto/notebooklm-skill notebooklmThe first time you use it, the skill sets up its own little Python environment and installs everything it needs automatically. You don't touch any of that.
Then log in once
Tell Claude to connect to your Google account. A Chrome window opens, you log in, and that's it. It stays connected after that.
Paste into Claude Code
Set up NotebookLM authentication.Section 5
Build Your First Knowledge Base
The skill connects Claude to NotebookLM, but you still create the actual notebook on the NotebookLM side. It's quick.
Go to notebooklm.google.com and click Create notebook.
Add your sources: PDFs, Google Docs, a website, a GitHub repo, even YouTube videos. Up to 50 sources per notebook.
Hit Share → Anyone with the link → Copy link. The skill needs the link to be shared this way to reach it. (Keep private docs in a dedicated account, more on that below.)
Back in Claude, hand it the link with the prompt below. Claude reads the notebook, figures out what's in it, and saves it to your library so you can call it by name later.
Add a notebook to your library
Paste your share link in place of the brackets. Claude does the rest.
Query this notebook to figure out what it covers, then add it to my NotebookLM library: [paste your share link]Section 6
The Prompts Worth Stealing
Once a notebook is in your library, you just talk to Claude. Swap the bracketed parts for your own stuff. These are the ones that earn the install.
Ask your own documents anything
The core move. Claude pulls a grounded, cited answer straight from the sources you uploaded. No hallucinated details.
Ask my [notebook name] notebook: [your question]. Use only what's in the sources and tell me what it cites.Research a topic from a stack of YouTube videos
Drop a handful of video links into a notebook, then have Claude pull the consensus across all of them at once. Hours of watching, compressed into one grounded answer.
Using my [topic] notebook, what do these videos actually agree on, and where do they disagree? Pull the strongest points and cite which source each came from.Turn a textbook or course into a study guide
Upload the material, then have Claude generate the study guide, the key terms, and a quiz to test yourself. Grounded in the actual reading, not the internet's vague version of it.
From my [subject] notebook, build me a study guide: the 10 key concepts, the terms I need to know, and 8 quiz questions with answers. Stay grounded in the sources.Build something without the hallucinated details
Point Claude at a notebook of real documentation or specs, then have it do the work. It checks the notebook for the exact details instead of inventing them, so you get it right on the first try.
I'm working on [the task]. Before you do anything, ask my [docs] notebook for the exact specs and requirements, then use only those. If something isn't in there, tell me instead of guessing.See everything you've saved
As you build more notebooks, your library grows. This lists what you've got so Claude can pick the right one automatically next time.

Tips And Honest Gotchas
Use a dedicated Google account.
The skill drives a real browser to talk to NotebookLM. That's normal automation, but Google can be twitchy about it. Set this up on a separate Google account, not your main one, and you've got nothing to worry about.
One notebook per topic.
NotebookLM is sharpest when each notebook is focused. Keep a "client X" notebook, a "course Y" notebook, a "research Z" notebook. Claude picks the right one when you name the topic.
Each question is a fresh ask.
The skill opens a clean session for every question, so it can't remember "the last answer." If you want a follow-up, include the context in the new question. Claude handles this well on its own when a task needs a few rounds.
The free tier has daily limits.
NotebookLM caps how many questions you can run per day on the free plan. Plenty for normal use. If you hit it, you'll just wait until the next day, no charge.
Most people use Claude as a really smart guesser. This turns it into something better: a researcher that actually reads your sources, cites them, and stops making things up, while Google quietly pays for the heavy lifting.
Set it up once. Build one notebook on something you actually care about, then ask it a real question. The moment Claude answers from your own documents instead of the internet's blurry memory, you'll get why this combo is worth it.
