Comparer du texte

Comparer deux textes et trouver les différences

Utilisez cet outil pour repérer les lignes ajoutées et supprimées entre un brouillon et une version modifiée — un vérificateur de diff léger, pas un éditeur de code.

Exact compare, ignore whitespace, ignore case

By default the checker compares lines exactly (after normalizing CRLF, LF, and CR line endings). You can optionally ignore whitespace differences or letter case. Options apply to comparison only; your pasted text is not rewritten.

Browser-local processing and privacy

Comparison runs in your browser. Your original and changed text are not sent to BizNavi Hub servers to compute the diff, and are not stored by this tool for later reuse.

Practical size limits

Very large pastes may be slower. Soft guidance starts around 500,000 characters per side; a hard limit of 1,000,000 characters per side and a line-count safety limit protect the page from freezing. There is no server fallback.

Business use cases

• Review policy or SOP wording changes before publishing.
• Compare email or ticket reply drafts side by side.
• Check localization strings or FAQ updates for unintended edits.

FAQ

Does my text leave the browser?

No. The diff runs locally for this tool; we do not upload your text to compute results.

What counts as a line?

Lines are split on CRLF, LF, or CR. A CRLF pair is one break, not two.

Can I ignore spaces or capitalization?

Yes. Enable ignore whitespace and/or ignore case. They can be combined and do not change the text you typed.

Is this a code merge tool?

No. It is a simple line-level text comparison for documents and copy—not a Git merge UI.

Which languages are supported?

The live UI is available in Japanese, English, German, French, Dutch, and Spanish. Polish is not live yet.
