What is a text diff?
A text diff compares two versions of text and shows what was added or removed. This tool highlights additions in green and removals in red so you can quickly see changes between drafts, configs, or code snippets. You can optionally ignore whitespace so only meaningful changes are shown.
Why compare two texts?
Comparing text is useful for reviewing edits, spotting config drift, or checking copied content. Instead of scanning line by line, you see exactly what changed. All processing runs in your browser; nothing is sent to a server. Use the Copy button to get a unified diff you can share or paste into version control.
How to use this tool
Paste the original text in the left panel and the changed text in the right panel. The diff result updates as you type. Turn on "Ignore whitespace" to treat spaces and line breaks as irrelevant. Click Copy to copy the diff as text, or Clear to empty both panels. For related tools, try Remove Line Breaks or Sort Text.
