info

If you create a KDB without uploading a document, its status is Draft, and you can’t use Playground or share it. After you create a KDB with a document, its status becomes Activating while the system analyzes the document. Once processing is complete, the status becomes Active, and you can use Playground and share it.

Edit a Knowledge DB

1. Open an existing Knowledge DB from the list (Click Knowledge DB on top menu > click (⋮) at each KDB card > click Edit)
2. Update fields, upload or remove documents, and adjust settings.
3. Click Save.

info

When a KDB’s status is Activating, the system is analyzing the document. While in this status, you can’t edit the KDB until processing finishes and the status becomes Active. You also cannot edit KDB created by others.
