Onity Group achieves 50% cost reduction and 20% accuracy improvement in mortgage document processing with Amazon Bedrock

Onity processes millions of mortgage servicing pages annually across hundreds of document types, but traditional OCR and AI/ML solutions could not reliably handle verbose legal text, inconsistent handwritten entries, notarization and legal seal detection, or limited contextual understanding.

Outcome

Onity achieved a 50% reduction in document extraction costs and a 20% accuracy improvement compared to their previous OCR and AI/ML solution. Home appraisal checklist review accuracy improved by 65% over the manual process, and credit report analysis achieved approximately 85% accuracy.

What failed first

Traditional OCR and ML models proved fundamentally limited for mortgage servicing documents, failing on four core challenges: verbose legal text with buried data elements, inconsistent handwriting style variations, notarization and seal detection requiring visual understanding, and lack of semantic context interpretation.
