# UI Data Loaders
UI data loaders give users flexibility to add real-time documents and data to the workflow.
The UI data loaders functions same as the ones available for knowledge base retrievers. The advantage of UI data loader over knowledge base is that it gives the flexibility for the frontend users to add their own document in the workflow for processing. Admin can also select if they want the documents uploaded by the users to be added to knowledge base or not for future processing. Similar to the knowledge base loaders, admin can either add static query for information retrieval or pipe variable from the workflow.
**These steps are applicable to all UI data loaders.**

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://document.unifiedstacks.com/workflow-elements/ui-data-loaders.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
