What is Text Compare?
Paste the original text on the left and the changed version on the right to see a line-by-line diff instantly: added lines highlighted green, removed lines highlighted red, unchanged lines shown as-is. Useful for comparing two drafts, catching what changed between file versions, or reviewing an edited config or code snippet. Everything runs in your browser; neither text is sent anywhere.
FAQ
Line by line. A single character change on a line marks the whole line as changed (removed from the original, added in the changed version), which is how most code and config diffs are read.
No hard limit, but very large texts (tens of thousands of lines) may feel slower since the comparison runs in your browser's main thread.
