How It Works

From custom form to validated enterprise JSON in seconds.

PayXtract standardizes proprietary documents across four intelligent automation stages.

01

Define Schema

Declare your JSON schema or describe target fields in plain English in the UI.

02

Zero-Shot OCR

The sovereign model understands layout semantics and maps text to your schema.

03

Validate Logic

Applies custom mathematical rules, regex checks, and confidence score thresholds.

04

Deliver JSON

Export structured payloads directly via Webhooks, REST APIs, or database inserts.

Where It's Used

Extracting any specialized enterprise format.

  • Clinical Pathology & Lab Diagnostic Reports — extract analyte values, reference ranges, and abnormal indicators.
  • Tax Filings & Financial Schedules — capture income declarations, deductions, and nested multi-column schedules.
  • Engineering Quality & Mill Test Certificates — parse chemical compositions, tensile strengths, and heat numbers.
  • Insurance Claim Intimation Slips — extract incident dates, policy numbers, claim amounts, and adjustor notes.
