1. What is text comparison?

Text comparison (or diff) is a tool that identifies and highlights changes between two pieces of text. It shows what was added, removed, or kept the same, making it easy to spot differences between documents, code versions, or any text content.

2. How does it work?

This tool uses the Longest Common Subsequence (LCS) algorithm to compute differences between two texts. It highlights additions in green and deletions in red with strikethrough, providing a visual representation of changes.

Diff Modes

Word Level - Compares text word by word, better for natural language and general text
Character Level - Compares character by character, more granular for precise changes

Statistics

Additions - Content that exists in the modified text but not in the original
Deletions - Content that was removed from the original text
Unchanged - Content that remains the same in both texts
