Diff Checker
Compare two texts side by side and see the differences highlighted. Find additions, deletions, and unchanged lines.
Frequently Asked Questions
How does the diff algorithm work?
This tool uses the Longest Common Subsequence (LCS) algorithm to find the optimal set of changes between two texts. It identifies lines that were added, removed, or remained unchanged.
Can I compare code with this tool?
Yes! The diff checker works great for comparing code, configuration files, or any text content. The monospace font and syntax highlighting make it easy to spot differences.
