The Challenge: Manual Loan Document Review Bottlenecks at BOCHK

BOCHK faced significant operational hurdles due to the manual comparison process for loan documents (term sheets vs. loan agreements). This traditional method was a major pain point for their analysts and the institution:

01Time-Consuming

  • 8 hours to review one document set
  • 5–8 files per analyst per week
  • Repeated checks on key terms

02Error-Prone

  • 3–5 critical differences often missed
  • Complex terms easily misread
  • Fatigue increased late-stage errors

03Hard to Train

  • 2-3 months to train new hires
  • All work reviewed by senior staff
  • High reliance on experience

The Solution

To address these critical needs, we designed and developed a Loan Document Review System. The tool fundamentally transforms the laborious document comparison workflow, as illustrated below:

Before and after comparison of loan document review process

The new workflow streamlines collaboration between analysts (Makers) and reviewers (Checkers) through intelligent automation:

For Analysts (Makers):

  • Easy Upload: Just upload the term sheet and loan agreement.
  • Smart Matching: The system compares documents and suggests clause matches with key differences highlighted.
  • Guided Review: Analysts confirm or adjust matches with clear guidance.
  • Quick Submission: A summary is generated for one-click handoff to the reviewer.

For Reviewers (Checkers):

  • Efficient Review: See confirmed matches and key differences in one view.
  • Fast Decisions: Approve or request changes with a single click.

Key Features & Functionality

Intelligent Document Upload and Auto-Recognition: Analysts upload documents, and the system auto-detects structure and key clauses—ready for comparison with minimal effort.

Clause Matching and Comparison View: Automatically finds related clauses, highlights changes, and shows before and after versions to make review easy.

Intuitive Dashboard: Gives analysts and managers a clear view of document status, flagged issues, and team progress to support better workflow management.

Result and Extension Thoughts

After six months of development, the tool now achieves 95% accuracy in real-world use. With a manual review step in place, it fully meets customer requirements. There's still room to improve accuracy further with future AI and machine learning enhancements. As a tool built to boost efficiency, it has successfully delivered on its purpose.

As AI and natural language processing continue to evolve, this tool also has potential for broader application. Industries like law, insurance, real estate, and healthcare all rely heavily on accurate document comparison. It would be valuable to explore how similar solutions could help people handle complex documents more easily across different fields.
