| Node | What it does | When to use |
|---|---|---|
| Read PDF | Extracts ALL text | When you need the full document text |

Tip
Ask Document is the most flexible Vision node: you can ask anything. Use Read PDF or Extract Text when you just need the raw text.
File URL sources
The file URL can come from:
- Webhook payload:
{{trigger.body.file_url}} - Form submission:
{{trigger.file_upload.url}} - HTTP Request:
{{http.body.download_url}} - Static URL: a direct link to a file hosted anywhere
Error handling
If the file can't be processed (corrupt, unsupported format, too large):
- The node fails with an error message
- Use Continue on error + If-Else to handle gracefully
- Check file type before processing with an If-Else on the URL extension
