Vergleichen Sie zwei Texte online – finden Sie jeden Unterschied sofort

Contracts, translations, code and documents evolve. Paste two versions and see exactly what changed, word by word, without uploading anything.

Wer braucht ein Textvergleichstool?

Lawyers reviewing contract amendments. Translators checking revisions. Developers comparing config files. Writers editing drafts. Anyone who needs to know precisely what changed between two versions of a text.

Wie funktioniert es?

The tool uses a longest-common-subsequence algorithm to match words between the two texts. Additions are highlighted in green, deletions in red with strikethrough. You see the exact count of additions and deletions at a glance.

Ist mein Text privat?

Yes. Both texts are compared entirely in your browser. No server sees your contracts, translations or confidential documents. This makes it safe for legal, medical or business texts that cannot leave your device.

Warum browserbasierte Hilfsprogramme verwenden?

Online utilities like password generators, text formatters, and URL cleaners are convenient, but most send your data to remote servers. Our browser-based tools process everything locally — your passwords, text, and URLs never leave your device.

This is especially important for sensitive operations like generating passwords, checking password strength, or cleaning URLs that contain tracking parameters. With Presend, you get the convenience of online tools with the security of offline software.
