Text Compare
Compare two blocks of text and see the differences highlighted line by line.
Why Compare Text?
Spotting differences between two versions of text is tedious when done manually. Whether you're reviewing code changes, checking document revisions, or verifying that a copy edit was applied correctly, a diff tool saves time and catches details you'd otherwise miss.
Common uses for text comparison include:
- Reviewing code changes before committing
- Comparing contract or legal document revisions
- Checking copy edits in marketing content
- Verifying configuration file changes
How the Diff Works
Line-by-Line Comparison
The tool compares your two texts line by line using a longest common subsequence algorithm — the same approach used by Git and other version control systems.
Added Lines
Lines that exist in the modified text but not in the original are highlighted in green, showing what was inserted.
Removed Lines
Lines that were in the original but are missing from the modified text are highlighted in red, showing what was deleted.
Tips for Comparing Text
Trim Whitespace
Trailing spaces and extra blank lines can create noise in your diff. Clean up whitespace before comparing for clearer results.
Compare Small Chunks
For large documents, compare section by section. This makes it easier to review changes and spot important differences.
Check Line Numbers
Use the line numbers in the diff view to quickly locate changes in your original files and verify each modification.
