# Document Loader - Workflow node | Docs - nodulz

Source: https://nodulz.com/docs/nodes/ai_document_loader

Language: en

Load text from URL or upstream data

## Usage and specifics

Source can be text or an HTTP URL. The executor reads the response as text; mimeType does not turn a binary PDF into text. Extract the document with a suitable node when needed.

Technical type : `ai_document_loader`. Runtime : `nodulz`.

## Credentials and prerequisites

This node defines no dedicated external credential. Remote sources or execution targets may still need their own access credentials.

See the [credentials guide](/docs/credentials) if a remote source or execution target requires access.

## Parameters

Names below are technical keys. Defaults are not a ready-to-run configuration: complete fields required by your operation. Paths containing [] describe list items; some fields depend on the selected mode.

| Parameter | Type | Default | Values / limits |
| --- | --- | --- | --- |
| `source` | `string` | `""` | - |
| `sourceMode` | `enum` | `"manual"` | `manual`, `node`, `file` |
| `mimeType` | `string` | `"text/plain"` | - |
| `documentId` | `string` | `"document"` | - |
| `documentUrl` | `string` | `""` | - |

## Initial configuration

Initial catalog configuration example, to adapt before running. Keep secrets in credentials.

```json
{
  "source": "",
  "sourceMode": "manual",
  "mimeType": "text/plain",
  "documentId": "document",
  "documentUrl": ""
}
```

## Verification

Test with representative data. Check node output in the inspector and logs, then use editor mapping for downstream fields. A trigger test with a simulated payload does not validate external service delivery.
