Frequently asked questions

How does text comparison work?
The tool uses diff algorithms to find minimal changes between two texts. It identifies: unchanged lines (context), removed lines (deletions), and added lines (insertions). Color coding shows exactly what changed between versions.
What is the difference between line, word, and character diff?
Line diff: compares whole lines, best for code. Word diff: compares individual words within lines, good for prose. Character diff: shows exact character changes, useful for finding typos. Choose based on your content type.
Can I compare code files?
Yes! The tool works well for code comparison. It handles different line endings (CRLF vs LF), ignores or highlights whitespace changes based on settings, and shows line numbers. For syntax-aware comparison, use your IDE\\
How do I read unified diff format?
Lines starting with - were removed; lines with + were added. @@ markers show line number ranges. Context lines (unchanged) have a space prefix. This is the standard diff format used in Git, patches, and version control.
Can I copy or download the diff results?
Yes, copy the highlighted diff to clipboard or download as a text file. The output can be used as a patch file for version control, documentation of changes, or review purposes.
