Comparing two documents for differences is a common task across many professions and academic pursuits. Whether you’re a lawyer reviewing contracts, a student checking drafts, or a business professional tracking revisions, the ability to pinpoint changes quickly and accurately is essential. Traditional methods of manual comparison are time-consuming and prone to errors. This is where specialized tools and techniques come into play, offering efficient and reliable ways to compare files and highlight discrepancies.

• Risk Reduction: Minimizes the risk of errors in contracts, legal documents, and other important files.

1.2 Common Challenges in Document Comparison

Despite its importance, document comparison can be challenging:

• Time-Consuming: Manual comparison is labor-intensive and can take hours, especially for lengthy documents.
• Error-Prone: Human error can lead to overlooking subtle but important changes.
