Executive Overview

FormFlow turns static paper forms, emailed PDF invoices, and scanned receipts into standardized database records using zero-shot AI vision processing.

1. What is FormFlow NLP?

Traditional OCR tools rely on brittle rigid templates. FormFlow uses multimodal LLMs that understand document semantics—regardless of font changes, table alignment, or orientation.

2. Vision-Language Model Pipeline

Documents are preprocessed, split into visual patches, and evaluated against JSON Schema definitions. Missing fields are automatically flagged with confidence scores.

3. Defining Target Extraction Schemas

You define target schemas using standard TypeScript interfaces or JSON Schema declarations:
json
{
  "$schema": "http://json-schema.org/draft-07/schema#",
  "type": "object",
  "properties": {
    "invoiceNumber": { "type": "string" },
    "vendorName": { "type": "string" },
    "totalAmount": { "type": "number" },
    "lineItems": {
      "type": "array",
      "items": {
        "type": "object",
        "properties": {
          "description": { "type": "string" },
          "qty": { "type": "integer" },
          "price": { "type": "number" }
        }
      }
    }
  },
  "required": ["invoiceNumber", "totalAmount"]
}

4. Document Parsing API Code Sample

Invoke the FormFlow vision parser in Node.js or Python:
typescript
import { FormFlow } from '@mixoop/formflow';

const formflow = new FormFlow({ apiKey: process.env.MIXOOP_API_KEY });

const result = await formflow.parseDocument({
  fileUrl: 'https://storage.mixoop.com/invoices/inv_99812.pdf',
  schemaId: 'schema_invoice_v2',
  confidenceThreshold: 0.85
});

console.log('Extracted Data:', result.data);
console.log('Confidence Score:', result.confidence);

Key Takeaway & Summary

FormFlow provides end-to-end intelligent document processing with 99.4% field accuracy across 40+ global document types.
