A suite of powerful, free text tools built for writers, developers, students, and anyone who works with text.

Our Mission

TextDiffy was created with a simple belief: powerful text processing tools should be free and accessible to everyone, without registration, without subscriptions, and without sending your data to a server.

We built TextDiffy because we were frustrated with existing tools that were either too complex, required sign-up, or hid basic features behind paywalls. Our goal is to provide a clean, fast, and private text tool suite that works in any browser, on any device, in any language.

TextDiffy currently includes 12 free text tools:

Privacy First

Every TextDiffy tool operates 100% client-side in your browser. Your text is never transmitted to our servers, never stored, and never analyzed by us. This makes TextDiffy safe for confidential documents, source code, private notes, and sensitive content.

Multilingual

TextDiffy is available in 13 languages: English, French, Spanish, Chinese, Arabic, Portuguese, Russian, German, Hindi, Japanese, Korean, Italian, and Turkish. The interface automatically adapts to your browser language, and you can switch languages at any time using the language menu in the navigation bar.

Open & Free

All 12 tools are completely free with no hidden costs. We support development through non-intrusive advertising. If you find TextDiffy useful, the best way to support us is to share it with colleagues and friends.
