Use this file to discover all available pages before exploring further.

The Datasets page lists all datasets in your workspace. Each dataset is a container for documents and all subsequent operations — see Datasets for the underlying concept.

​
Dataset list

Each row shows:
  • Name — The dataset identifier.
  • Documents — Number of files in the dataset.
  • Created — Creation timestamp.
  • Status — Ready (has documents) or Empty.
Use the search bar to filter datasets by name.

​
Create a dataset

Click New Dataset, enter a name, and confirm. The dataset is created immediately and appears in the list.

​
Upload documents

  1. Select a dataset from the list (or create one).
  2. On the dataset detail page, drag files into the upload area or click to browse.
  3. Supported formats: PDF, CSV, TXT, Markdown, JSON, DOCX.
After upload, the add and cognify pipeline runs in the background. The header shows Processing… while the knowledge graph is being built. When processing finishes, the header updates to show a Last synced timestamp.

​
Sync a dataset

For datasets connected to an external source, the dataset detail page includes a Sync button that re-runs the cognify pipeline against the current dataset contents. Use this to rebuild the knowledge graph after source data changes without uploading new files again. While syncing, the button shows a spinning icon and the label Syncing…. The Last synced timestamp updates when the sync completes.

​
Dataset breadcrumb

The breadcrumb at the top of the UI follows the structure Workspace / Dataset / Page. The dataset selector appears only on pages where filtering by dataset is relevant: the Dashboard, Search, Knowledge Graph, and dataset detail pages. On other pages the breadcrumb shows only the workspace and current page name. Selecting a dataset in the breadcrumb is global — it filters content across all applicable pages:
  • The Search page queries only that dataset.
  • The Knowledge Graph page visualizes only that dataset’s graph.
  • The Dashboard scopes metrics and search to that dataset.
To search or visualize across all datasets, set the breadcrumb back to All datasets. On a dataset detail page the breadcrumb shows Workspace / [Dataset] / Documents.

​
Delete a dataset

Open the context menu on a dataset row and select Delete. This removes the dataset, all its documents, and the associated knowledge graph. This action cannot be undone.
Dataset operations are also available through the REST API and the Cloud SDK.
