Setting Up Gemini
Gemini is Google's AI. Because it comes from Google, it can reach into your Gmail, your Google Drive, your Docs, and your Calendar, which sounds small, but turns out to be a big deal once you use it.
This page does two things. First, it gets you into Gemini itself. Second, it opens a second, different Google AI tool called NotebookLM, which is worth using even if your main chat tool ends up being ChatGPT or Claude. Both are worth having. Total time: about twenty minutes.
If you're still deciding between tools, the Pick a Tool page compares Gemini, ChatGPT, and Claude honestly. Gemini's real edge is that it lives inside Google, so it can reach your Gmail, Docs, and Drive directly, and NotebookLM has no close equal in the other tools.
Part one: Gemini
Getting to Gemini
Open a new tab. In the address bar at the top, type:
gemini.google.com
Press Enter.
What you should see: a page with "Gemini" at the top, probably a colorful gradient somewhere, and either a sign-in screen or a chat box (depending on whether you're already signed into a Google account in this browser).
Signing in
If it asks you to sign in, click Sign in and choose the Google account you already use for Gmail. There's no separate signup for Gemini; it comes bundled with every Google account.
If you have multiple Google accounts (personal Gmail, work Workspace, etc.), pick the one you want to be your "main" one for this. You can always switch later.
What you should see after signing in: a main chat screen with a text box near the bottom and a sidebar on the left showing past conversations.
If your Google account is through a business or a school (anything that isn't a plain @gmail.com), that's a Workspace account. Workspace accounts get stronger privacy: Google generally doesn't use your data to train models. Prefer a Workspace account over a personal Gmail if you have one.
About the plans
Gemini is free to start. Enough to get comfortable.
For the work in this guide you'll eventually want Google AI Pro (about $20 a month). It gives you:
- Access to the better, more careful Gemini model (currently called "2.5 Pro" or similar; the name keeps changing).
- A much bigger memory for each conversation.
- Higher limits inside NotebookLM.
If you already pay for Google One (extra Drive storage), check whether AI Pro is already bundled into your plan; sometimes it is.
To upgrade: click your profile picture in the top-right corner. Look for Google AI Pro or Upgrade. Don't worry about this today.
Connecting Gemini to your Google apps
This is the part that makes Gemini different from Claude and ChatGPT. You can let it look into your Gmail, Drive, Calendar, Docs, and more, so when you ask "what did I agree to in the thread with Jennifer last week?", it can go look.
Find the connections menu. Inside Gemini, look near the top right of the page. You're looking for an icon that looks like a puzzle piece, or a button labeled Apps or Extensions. Google renames it every few months, so don't panic if it looks slightly different.
Click it. You'll see a list of Google apps with little on/off toggles next to each one.
Turn on:
- Gmail: lets Gemini look at your inbox when you ask.
- Google Drive: lets it pull up files from your Drive.
- Calendar: lets it see your schedule.
- Docs: (usually comes with Drive) lets it read your Google Docs.
Each time you turn one on, Google will ask you to confirm; it'll show you what that connection can and can't see. Click through and agree.
You can turn any of these off with one click, any time. If you're nervous, start with just Gmail and Drive. Add the others later.
On a personal Gmail, your data is covered by Google's normal privacy rules. On a Workspace account, your data isn't used to train models by default.
One small test
Type this into the Gemini chat and press Enter:
Look at my Gmail. Summarize the most recent email I've received, in three sentences, without opening a new message window.
What should happen: Gemini asks for permission (the first time only), then reads your most recent email and writes a quick summary.
If it says it can't access Gmail: go back to the connections menu and make sure Gmail is toggled on. Sometimes you need to refresh the page for a new connection to take effect.
Part two: NotebookLM
Now the quiet standout. NotebookLM is a separate Google AI tool, at a different web address, that almost nobody has heard of. It is free and worth using even if your everyday chat tool is ChatGPT or Claude. It isn't a competitor to them; it does a different job.
Here's the idea: you give it a pile of documents, and from that point on it only answers using those documents. It shows you the exact sentence every answer came from. You can click any claim and jump straight to the source. This makes it nearly impossible for NotebookLM to make things up.
When you want the AI to be strict and fact-based, for research, for studying a dense PDF, for making sense of a stack of your own notes or reports, NotebookLM is what you use.
A plain chatbot answers from its own hazy memory of the whole internet, which is exactly when it invents confident-sounding nonsense. NotebookLM flips that: it answers only from the sources you hand it, and every claim links back to the exact sentence it came from. That's the single most reliable habit in this whole guide: give the AI your real sources instead of trusting what it thinks it remembers. When a number, a quote, or a fact has to be right (a figure in a report, a line in a contract, a claim in a paper), work in NotebookLM so you can click straight through to where it came from.
Getting to NotebookLM
Open a new tab. Type this in the address bar:
notebooklm.google.com
Press Enter. Sign in with the same Google account.
What you should see: a mostly empty page with a big button in the middle that says Create or + New notebook.
Making a test notebook (so you see how it works)
You're not building your real notebook yet; that comes later, on the Your Work page. For now, you're just playing with one article so you see how it works.
Click Create.
What you should see: a new screen with three columns. On the left, an empty Sources area. In the middle, a chat. On the right, a panel called Studio. If you don't see all three, your browser window might be too narrow, so make it wider.
Adding your first source
In the left column, click Add source (or the big + sign).
A pop-up appears with options. Pick Website (or sometimes called URL or Link).
Paste in any long article you've read recently: a newsletter, a blog post, a news story. Anything. Click Add or Insert.
NotebookLM will think for a few seconds while it reads the article. You'll see it appear in the left column when it's done.
Asking a question
Now click in the chat box in the middle and type:
What are the three main arguments this article makes? Quote a sentence from the article for each one.
Press Enter.
What you should see: an answer with little numbered circles in it, like little footnotes. Those are citations. Click on any one of them.
What should happen when you click: NotebookLM pops open a side panel showing the exact sentence in the exact source where that claim came from. That's the magic. Every answer is traceable.
Try the audio overview
On the right side of the screen, in the Studio panel, look for a button called Audio Overview.
Click it. Click Generate. Wait about a minute.
When it's done, hit play. What you'll hear is two AI hosts having a ten-minute podcast conversation about the article you just uploaded, as if they're radio hosts who just read it together and are discussing it.
It's a strange and oddly delightful way to absorb information. Especially good for long articles you don't feel like reading all the way through.
Gemini: for everyday questions, quick help, and anything that needs to reach into Gmail, Drive, or Calendar.
NotebookLM: when you want reliable, cited answers from specific documents you've uploaded. Research. Studying a PDF. Making sense of a transcript, a stack of reports, or your own notes. Worth opening even if your main chat tool is ChatGPT or Claude.
Quick check
What is NotebookLM's superpower, the thing that makes it different from a regular chatbot?
Answer: NotebookLM is a grounded AI: it only answers from the sources you've given it, and every claim links back to the exact sentence in the exact source. Nothing invented.
That's why it's the right tool when accuracy matters, working through a research paper, a set of financial statements, lecture notes, or a long report, not for creative drafting.
Where to check this
Gemini's apps, plans, and connections change often, and NotebookLM keeps gaining features. For current details, check Google's own help pages: support.google.com/gemini for Gemini, and notebooklm.google.com for NotebookLM. Search there for a feature name if something has moved since this was written.
