Text Diff Checker

Free text diff checker, Git style

Paste or import two versions of a text to see, line by line, what was added, removed or changed, like a Git diff but for any text. It helps to review a contract, compare two versions of an article or check the changes in a configuration file. Everything happens in your browser: nothing is sent to a server.

Changed lines highlighted word by word

When a line is simply reworded, the tool shows it as one modified line and highlights only the words that changed, instead of a whole line removed then a whole line added. Lines are only joined when they are similar enough, so unrelated lines are never fused. Turn the option off to see the raw removals and additions.

Import, compare, export

Import a text file on each side, ignore case, spaces or punctuation as needed, switch between side by side and unified views, and compare by line, word or character. Long texts are compared in the background and long unchanged stretches are folded. Copy the result or download it as text or as a standalone HTML page.
