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. - ### Works with Gemini Notebook's own collections 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](/features/tags-and-source-labels) 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. ## Gemini Notebook’s own collections Switch to **Gemini Notebook** to see Google’s own collections, read live. **Create collection using Gemini Notebook** makes one there. **Move your Kortex collections to Gemini Notebook** copies your Kortex folders across. ## How it works Want every step?
