Text Compare — A word-level diff with a clean side-by-side view. The text on the left is the "before" version; the right is "after". Words that exist in only one version are highlighted; unchanged text stays neutral so your eye can scan for the actual changes.
Both texts are compared entirely in your browser. Nothing is sent to a server. The output stays in the page; closing the tab discards it.

Qu’est-ce que Text Compare ?
A word-level diff with a clean side-by-side view. The text on the left is the "before" version; the right is "after". Words that exist in only one version are highlighted; unchanged text stays neutral so your eye can scan for the actual changes.
Unlike the line-level text-diff tool, this one never cuts the text into arbitrary lines — it preserves the full text and just flags what changed at the word level. Better for prose; for code, the line-level text-diff tool is the right fit.
