# Bulk and Single Generation
The **Content Generation** Menu allows you to access two different actions (Bulk and Single) for Knowledge Generation from Tickets, via the AI Generated Documents window.
Choose **Content Generation > AI Generated Documents** to access the window that now includes 2 tabs in the upper-left corner - **Bulk** and **Single**.
The **Bulk** tab on the **AI Generated Documents** window displays the Knowledge Base Articles that were generated from **Bulk Tickets** to create information **Clusters**.
The **Single** tab on the **AI Generated Documents** window displays the Knowledge Base Articles that were generated from [**Individual Tickets**](https://docs.aisera.com/agent-assist/how-to-setup-agent-assist/integrating-agent-aisera-assist-within-servicenows-service-operations-workspace/single-ticket-knowledge-generation). This ability is limited to the **Agent Assist** channel.
**Delete & Regenerate Docs to Improve Quality**
The release introduces the ability to delete documents that are not helpful, allowing their associated tickets to be reconsidered in future job runs. You can now regenerate documents from the same tickets after adding new comments.
**Document Deletion Capabilities**
A new **Delete Document** option is now available in the Actions dropdown, in both the **Bulk** and **Single** tabs of the **AI Generated Documents** window. You can select one or multiple documents within a cluster and go to **Actions > Delete Document**.
A confirmation message appears: "Are you sure you want to delete the selected 1 document(s)?”
Deleted documents are greyed out in the UI rather than removed, ensuring the **Data Processing Funnel** remains consistent with the original cluster count.
If all documents within a cluster are deleted, the job is also deleted. The corresponding **Job Name** is automatically removed from the **Job Filter** dropdown.
The corresponding **Job Name** is automatically removed from the **Job Filter** dropdown.
For the documents deleted from Single tab of the AI Generated Document page then the document will be removed instead of greyed out because document generation from a single ticket doesn’t use a processing funnel.
Greyed-out documents are non-clickable and non-actionable.
When an AI-generated document is approved and committed, it becomes part of the **similarity check**. If a committed document is later deleted from the **AI Generated Documents** page, it will be removed from the similarity dropdown for any document it was previously matched with, and the similarity count will be updated accordingly.
If the deleted document was the only similar match, the similarity status will be updated from **Yes** to **No**.
