Teachers use Kortex, a Chrome extension for Gemini Notebook (formerly NotebookLM), to build a notebook per unit from their own Google Docs, YouTube playlists and articles, and to keep every quiz, study guide and slide deck it makes in one list. Next term they duplicate the notebook instead of starting again, and Sync Google Docs keeps their Docs current.
You already have the material. Kortex helps you reuse it, not rebuild it.
Your materials live in Google Docs, on YouTube and in a dozen bookmarked articles.
Send a Doc from inside Google Docs, a whole YouTube playlist, or a highlighted passage from any page straight into the unit’s notebook.
You edit the lesson Doc, and the notebook still has last week’s version.
Sync Google Docs pulls the latest version of every Doc source in one click.
A quiz, a study guide and slides for every unit takes the weekend.
Set the amount and difficulty and generate them from the unit’s sources. Generate several at once and edit them before you download.
Last year’s quiz is in a notebook you can’t find.
All Artifacts lists every quiz, study guide and slide deck with its notebook, in folders you choose, and search finds the rest.
Every term starts from a blank notebook.
Duplicate a unit’s notebook in one click, or save it as a template and apply it to new ones.
From the first lesson Doc to next term’s copy of the notebook.
One notebook holds the unit’s Docs, videos and readings.
Class materials drafted from your own sources, all in one list.
Edit the Doc, and the notebook follows.
Last term’s course, copied and filed before the first lesson.
Quoted word for word and linked to where they were posted. Reviewers don’t say what they do for a living, so we picked reviews about the features on this page.
“Kortex solves such a practical problem. NotebookLM is powerful, but managing sources across multiple projects can get messy fast. Having a centralized way to organize, import, and export those sources with a click is exactly the kind of workflow improvement that saves hours over time.”

Yes. Teachers can apply for the creator and class pass with a school email (.edu, .ac.uk and similar) and are approved straight away. Their students then get a discount on their first year.
Kortex doesn’t change who can see a notebook. Sharing happens in Gemini Notebook, and students see the notebooks you share with them. Your tags, prompts and templates stay in your Kortex account.
Not directly. Kortex works with Gemini Notebook and Google Docs. A shared notebook is a link, so you can post it in Classroom like any other.
Kortex runs in Chrome, Edge, Brave and other Chromium browsers. On a school-managed device, the admin decides which extensions can be installed, so check with them first.
Kortex doesn’t store your chats or the contents of your sources; what you import goes from your browser to your own Gemini Notebook account. Follow your school’s rules on what student work can go into an AI tool.
Add Kortex to Chrome and send your first lesson Doc to a notebook. Teaching a class? Apply for the class pass.
