About Text Diff / Compare
Our free Text Diff / Compare tool highlights the differences between two versions of text line by line - additions in green, removals in red - so you can quickly spot exactly what changed between two drafts or files.
Result
Paste your original and revised text into the two boxes and get an instant side-by-side comparison, making it easy to review edits, track changes between document versions, or compare two pieces of code without scanning line by line yourself.
Who Uses This Tool
Writers and editors use it to see exactly what a collaborator changed in a document draft before accepting the edits. Developers use it to compare two versions of a config file, snippet, or commit message text when a full diff tool isn't handy. Students and researchers use it to check how much a revised paragraph differs from an earlier version before submitting work. Translators and proofreaders use it to confirm that only intended sections of a translated document were altered. Because everything runs in the browser and results appear instantly, it works well as a quick sanity check before pasting text into a more formal version control or document review workflow.

Frequently asked questions
What does this tool compare - words or whole lines?
It compares line by line, highlighting which lines were added, removed, or changed between the two versions of text you paste in.
Can I compare code, not just plain text?
Yes - line-based diffing works for code, configuration files, or any plain text, not just prose.
Is my text uploaded anywhere?
No - the comparison runs entirely in your browser; neither version of your text is sent to or stored on our servers.
