What is DeepTagger?

DeepTagger uses machine learning to extract structured information from documents automatically. Instead of writing complex extraction rules, you simply annotate a few example documents, and DeepTagger learns to extract similar data from new documents. It's perfect for automating data entry from invoices, receipts, forms, contracts, and other business documents.

What does this node do?

The DeepTagger node allows you to:
- Extract structured data from documents (PDF, images, text) using pre-trained DeepTagger projects
- Process both files and text - upload documents or send text directly
- Return structured JSON - get clean, structured data ready for use in your workflows
- Automate document processing - integrate document intelligence into your automation workflows

Prerequisites

- An active DeepTagger account
- A DeepTagger API key (available in your account settings)
- At least one trained DeepTagger project with a Project ID

Installation

$3

n8n Cloud users can install this node directly from the n8n interface once it has been verified by the n8n team.

$3

Install the node using npm:

``bash
npm install n8n-nodes-deeptagger
`

Then restart your n8n instance. The DeepTagger node should now appear in your node list.

Alternatively, you can install it directly from the n8n interface by going to Settings > Community Nodes and entering n8n-nodes-deeptagger.

Troubleshooting

$3

Solution: Make sure you've configured your DeepTagger API credentials correctly. The API key must be set in the credentials and properly selected in the node.

$3

Solution: Verify your Project ID is correct. You can find it in the URL when viewing your project at https://deeptagger.com/das/fos.

$3

Solution:
- Restart your n8n instance after installation
- Check that the package is installed: npm list n8n-nodes-deeptagger
- For n8n Cloud, wait for the node to be verified by the n8n team

$3

Solution:
- This node uses your trained DeepTagger projects. If results aren't accurate, you may need to:
- Add more training examples in DeepTagger
- Review and correct annotations in your project
- Check that you're using the correct Project ID for the document type

$3

Solution:
- Ensure the previous node outputs binary data in the property you specified (default: data`)
- Use the Move Binary Data node if needed to reorganize your binary properties
- Check that the file type is supported by your DeepTagger project
