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.

Perfect for automating data entry from:

  • :material-file-invoice: Invoices - Extract totals, dates, vendor info
  • Receipts - Parse expense details
  • Forms - Structured field extraction
  • Contracts - Key terms and metadata
  • Any business document - Custom schemas

Primary Use Case: n8n Workflow Automation

The DeepTagger n8n community node is the recommended way to use DeepTagger for most users.

n8n Cloud & Self-Hosted Support

The DeepTagger node works on both n8n Cloud (after verification) and self-hosted n8n instances (available now on npm).

Why n8n + DeepTagger?

Common Workflows:

  1. Invoice Processing - Email → Extract → Accounting System
  2. Receipt Management - Cloud Storage → Extract → Expense Tracker
  3. Form Processing - Webhook → Extract → CRM/Database
  4. Contract Analysis - Document Upload → Extract → Review Notification
  5. Batch OCR - Scheduled → Process Folder → Archive
