SMALL CHANGES. CLEARER TEXT.

About Us

TextDiffTool helps you see what changed, understand the details, and decide what to keep. A simple task deserves a simple tool.

One place to compare your two versions

Whether you are editing an article, checking a contract revision, reviewing source code, or comparing a list, finding the differences by eye takes time. TextDiffTool puts your original and modified text in one workspace and highlights additions, removals, and edits.

Our aim is to make that everyday work clearer for writers, editors, developers, students, and anyone checking a revision.

Useful from the first comparison

  • Choose your detail. Compare by word, character, or line, with side-by-side and unified results.
  • Review at your own pace. Move between changes, accept or reject them, and build a merged version starting from the original.
  • Work with text or code. Paste your text or import UTF-8 plain-text files, with optional syntax highlighting for code.
  • Keep what you need. Explicitly save a draft in this browser, copy your results, or download a comparison report.

Free access, without an account

The core comparison, review, draft, and export features are free. There is no registration, subscription, or payment required to use them.

Your text stays on your device

Comparisons and imported files are processed locally in your browser. Your editor content is not uploaded to a server or placed in a sharing URL. Drafts are stored only when you choose to save them, in the browser where you saved them.

Read our Privacy Policy for details about browser storage, downloads, and website requests.

Help make the next comparison better

Clear feedback helps us improve the tool. If something is confusing, a result seems wrong, or a small change would make your work easier, get in touch. You can use invented sample text to explain an issue without sharing a private document.
