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

The problem

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.

First attempt

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.

1
Document upload to S3
trigger
“Documents are uploaded to Amazon Simple Storage Service (Amazon S3). Uploading triggers automated processing workflows.”
2
Document preprocessing
ai_action
“Before analysis, documents undergo optimization through image enhancement, noise reduction, and layout analysis. These preprocessing steps help facilitate maximum accuracy for subsequent OCR processing.”
3
Classification with confidence routing
routing
“Extracted content is processed by Onity's custom AI model. If the model's confidence score meets the predetermined threshold, classification is complete. If the document isn't recognized because the model isn't trained with that document…”
4
Dynamic extraction via Textract or Bedrock
ai_action
“It then dynamically routes extraction tasks between Amazon Textract and Amazon Bedrock FMs based on the complexity of the content. For example, verifying notarization requires complex visual and textual analysis. In these cases, the appl…”
5
Extracted data persistence
output
“The extracted information is stored in a structured format in Onity's operational databases and in a semi-structured format in Amazon S3 for further downstream processing.”
Reported 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.
