Kortex puts each course’s lecture videos, readings and the AI chats that finally made sense into one Gemini Notebook, then finds any of it in a second.
Saved to BIO 204: Cell biology ChatGPT: Why does the Krebs cycle need oxygen?
An example Workspace: a collection for the term, a notebook for each course, and a ChatGPT chat that just landed in Biology.
How do students use Kortex?
Students use Kortex, a Chrome extension for Gemini Notebook (formerly NotebookLM), to send lecture videos, readings and the AI chats that explained things best into one notebook per course, then find any of it with one search. At exam time they reuse saved study prompts and pull every study guide, quiz and flashcard set into one list.
Where a semester’s notes go missing
None of this is about studying harder. It’s about finding what you already worked out.
The explanation that finally clicked is in a ChatGPT chat from week three.
A Send to Notebook button in ChatGPT, Claude, Gemini and Perplexity saves the whole chat into the course notebook, with your questions and the replies labelled.
Lectures are on YouTube, readings are PDFs and tabs, and your notes are somewhere else.
Send a lecture video or a whole playlist from YouTube, highlight a paragraph on any page and right-click to send it, or send a Google Doc from inside Docs.
By week six the notebook list is a wall of “Untitled notebook”.
File each course in a collection for the term, tag notebooks by course code, and press / in the Kortex Workspace to search every notebook, source and note at once.
Exam week, and the study guides are spread across a dozen notebooks.
The All Artifacts view lists every study guide, quiz and flashcard set Gemini Notebook made for you, with the notebook each came from.
You retype the same “make me flashcards” prompt every time.
Save it once in your Prompts library and drop it into any chat box by typing its ;shortcut.
Four routines for the term
Each one uses features that exist today.
Set up a notebook for each course
Ten minutes in week one saves the scramble in week ten.
In the Kortex Workspace, create a notebook for the course and file it in a collection for the term, like Fall 2026.
Open the course playlist on YouTube and send it to the notebook. Each lecture becomes its own source.
While you read, highlight the passages that matter and right-click to send them. Each one keeps the page link and the date.
Tag the notebook with the course code, so search and filters find it later.
Save the AI chat that explained it
Your best explanations end up next to the lecture they explain.
When ChatGPT, Claude, Gemini or Perplexity finally explains a topic well, click the Kortex button on the chat.
Pick the course notebook, or create one. The chat arrives as a clean source, with your prompts and the replies labelled.
Ask Gemini Notebook a question across the lecture and the chat together. Its answer cites the source each point came from.
Kept chatting after you saved it? Send it again and Kortex updates the source instead of adding a copy.
Build the exam review kit
A study guide, flashcards and a quiz for each course, all in one list.
Open the course notebook and insert your exam study guide prompt from the Prompts button, or type its ;shortcut.
Generate a study guide, flashcards and a quiz, with the amount and difficulty set first.
Generate several types in one go, then preview and edit each one before you download it.
Before the exam, open All Artifacts, filter by the course, and download what you need.
All Artifacts
The real All Artifacts view in the Kortex Workspace.
Listen to a course review
An Audio Overview of each course, in the podcast app you already use.
From the notebook’s row in the Workspace, generate an Audio Overview. Pick Brief or Deep Dive, set the length and say what to cover.
Add it to your own podcast. Each podcast has a private feed link for Apple Podcasts, Pocket Casts, Overcast or any app that takes one.
Set a rule once: when a notebook moves into your Revision collection, generate its audio and add it to the podcast.
What reviewers say about these features
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.
“Easy to use and works well! Just click on the NotebookLM button in a chat, and you will be prompted to add the chat to a new project or existing one. The newly created source is formatted very cleanly, with prompts and responses indicated clearly (no extra random characters, etc.)”
“Brilliant! Is going to save me hours. I can make all sorts of enquiries in Gemini and then Kortex consolidates them into a single notebook where I can review what I have found and make sense of it all. Thank you.”
If your teacher has a Kortex class pass, their code takes 30% off your first year. The pricing section has the rest.
Do I still need Gemini Notebook?
Yes. Kortex is an extension that works in and around Gemini Notebook (formerly NotebookLM), with the Google account you already use there. Gemini Notebook reads your sources and answers; Kortex gets things in, keeps them organized and gets them back out. Whether Google’s own paid tiers are free for you is a separate question, answered in is Gemini Notebook free for students?
Can I import a whole YouTube playlist?
Yes. Kortex can send one video, a playlist, a channel’s uploads or the videos from a search, and each video becomes its own source. Gemini Notebook still caps how many sources one notebook holds, and Kortex stops and tells you when a notebook is full.
Will it work on my school Chromebook?
Kortex runs in Chrome, Edge, Brave and other Chromium browsers, including Chrome on a Chromebook. If your school manages the device, its admin decides which extensions you can install, so ask them if the Chrome Web Store blocks it.
Does Kortex keep copies of my notes?
No. Kortex doesn’t store your chats or the contents of your sources: imports go from your browser to your own Gemini Notebook account. It keeps what you make in Kortex, like prompts, tags and folders. Signed in, it syncs them across your computers.
Start with this week’s course.
Add Kortex to Chrome, open a lecture or a chat, and send it to a notebook.
