About this tool

Ever needed to find exactly what changed between two versions of a document? Scanning line by line with your eyes is slow and easy to get wrong. The text diff tool lets you compare two texts quickly. Just paste the original and the new version into the two boxes and it highlights clearly which lines were added and which were removed.

This diff online view lets you spot changes in an instant, which suits many tasks:

  • Comparing two versions of code to see what was edited
  • Reviewing a draft contract or legal document for changed wording
  • Checking how a revised article or translation differs from the original
  • Auditing copied-and-edited content for anything added or missing

Instead of squinting to find differences character by character, you let the tool highlight them for you. Developers, writers, editors and anyone working with documents rely on text comparison like this to save time and reduce mistakes.

The big advantages are privacy and convenience. Every comparison happens inside your own browser, so the text is never sent to a server. That keeps work documents and confidential information safe. The tool is free, needs no installation and no signup, and works the same on phone or desktop. Paste your two texts and see the differences right away, whether you are diffing a short paragraph or a long file.

How to use

  1. 1Paste the original text into the left box
  2. 2Paste the text you want to compare into the right box
  3. 3See the result with added and removed lines highlighted
