How to use

  1. Paste or upload the original text on the left and the modified text on the right. Both sides are editable.
  2. Differences are highlighted immediately, including the exact characters that changed within a line.
  3. Use the arrows to step through changes, switch to Inline for a unified view, or ignore whitespace-only changes.

Compare any two texts

This text diff checker uses the same comparison engine as Visual Studio Code, so results are accurate for source code, configuration, logs, CSV exports and plain prose. It shows moved and modified lines side by side, highlights character-level changes, and runs entirely in your browser.

Frequently asked questions

Removed lines are red on the left, added lines are green on the right, and within changed lines the exact characters that differ are highlighted more strongly. Unchanged regions stay neutral so you can focus on what changed.
