FAQ
What algorithm is used for the diff?
The tool uses the Longest Common Subsequence (LCS) algorithm, a standard approach for computing line-by-line differences. It identifies the longest sequence of matching lines and marks everything else as additions or deletions.
Can I compare any kind of text?
Yes. The tool works with any plain text including source code, configuration files, prose, CSV data, and more. It performs a line-by-line comparison regardless of the content type.
What do the colors mean?
Green lines are additions (present in modified but not original). Red lines are deletions (present in original but not modified). Uncolored lines are unchanged between the two versions.
Is my data sent to a server?
No. All diff computation happens locally in your browser. Your text and code never leave your device, making it safe for proprietary or sensitive content.
What is the difference between unified and split view?
Unified view shows all changes in a single column with + and - prefixes, similar to git diff output. Split view shows the original and modified files side by side for easier visual comparison.
Can I copy the diff output?
Yes. Click the Copy Diff button to copy the unified diff to your clipboard with standard + and - prefixes for added and removed lines.
