# Uploading Files

## Upload methods

### Drag and drop

Go to the **New File** tab and drag files directly onto the drop zone. You can drop up to 50 files at once.

### YouTube links

Paste a YouTube URL into the upload area. Knowbase downloads the transcript and makes it searchable.

### From connectors

If you've connected Google Drive, Notion, or Dropbox, you can import files directly from those services. See [Connectors](/connectors/connectors.md).

3. **Ready** — file is searchable and available for chat

**Processing time** depends on the file type. Documents take seconds; long videos may take several minutes for transcription.

## 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://docs.knowbase.ai/knowledge-base/uploading-files.md?ask=<question>&goal=<endgoal>
```

`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.
