Ce que fait cet outil

Qu est ce que c est

Text Diff Checker is a free online tool for comparing two versions of the same text. Instead of reading line by line and guessing what changed, you get a clear visual diff that marks removed text and new text immediately.

That makes it useful for copy edits, policy updates, UI labels, product descriptions, notes, and any workflow where you need to review revisions without losing the original context.

Quand l utiliser

Use it when a draft has been revised and you need to approve the changes quickly. Word mode helps with rewritten phrases and paragraph edits, while character mode helps with punctuation, spacing, and smaller copy tweaks.

It is especially useful for content reviews, localization checks, legal copy updates, support macros, documentation edits, and any team workflow where one version replaces another.

Usage

Comment utiliser l outil

  1. 1

    Paste the original text in the first field and the updated text in the second field.

  2. 2

    Choose word diff or character diff depending on whether you want to review larger wording changes or tiny edits.

  3. 3

    Switch between side by side and inline view, then inspect the highlighted additions and removals.

Exemples

Exemples pratiques

Reviewing revised headlines or CTA copy

Use word mode to see how a headline, subheading or call to action changed without rereading both versions from scratch.

Checking small legal or UI copy edits

Use character mode when punctuation, hyphens, casing or short wording changes matter and the smallest edit can change meaning.

A eviter

Erreurs courantes

Using character mode for large rewrites

Character diff becomes noisy when entire sentences are rewritten. Start with word mode if the structure of the sentence changed a lot.

Using inline view when full context matters more

Inline diff is compact, but side by side is often easier when you need to read both versions as complete text blocks.

Ignoring formatting changes hidden in pasted text

Extra spaces or line breaks can affect the result. If the diff looks bigger than expected, check whether the pasted versions contain formatting noise.
