What are Kortex collections and folders?
Collections are Kortex's folders for notebooks in the Kortex Workspace. They can hold subfolders and have a color, and you can pin up to three. Source folders and artifact folders do the same for sources and Studio outputs.
What you get
-
Group by project, not by date
Put the notebooks for a thesis, a client or a trip in one collection. Open them together instead of scrolling a long list.
-
Nest, color and pin
A collection can hold sub-collections and has its own color. Pin up to three so the ones you use daily stay on top.
-
Sources and outputs get folders too
Source folders group sources from all your notebooks. Artifact folders do the same for Studio outputs such as briefings and slides.

A switch on the Collections page shows Gemini Notebook's own collections, read live. A button can copy your Kortex folders across.
What is a collection?
A collection is a folder for notebooks. You make and manage them in the Kortex Workspace, the full-tab dashboard (the extension calls it the dashboard). Open Collections in the sidebar. You see two switches: Kortex, for Kortex’s own folders, and Gemini Notebook, for Google’s own collections.
Kortex folders can hold subfolders. A collection called Thesis can hold one folder per chapter. Each folder has a color, and you can pin up to three. The page shows each folder with its item count.
Folders for sources and Studio outputs
Notebooks are not the only thing that piles up. The Sources view has source folders (All Folders, Unfiled) that group sources from all notebooks. The Artifacts view has folders for Studio outputs, with New Folder beside the filters. Select rows and choose Move to Folder to file them.
Smart Collections
Choose Smart Collection when you make a folder, and give it rules. Notebooks that match all the rules are included without you moving them. Tags are the usual rule. Tag a notebook and it appears in the collection.
Generate for collection makes a Studio output, such as an Audio Overview or a study guide, for every notebook in one collection.
