A LITTLE GUIDANCE

How to use this tool

  1. Place the original and revised text in the two input boxes.
  2. Choose word or line comparison and select Compare text.
  3. Review the additions and removals, then copy or download the marked comparison.

A worked example

Before: red / blue. After: red / green. The second line shows one removal and one addition.

What to know

Comparison is case sensitive and includes whitespace. Added text is underlined and removed text is struck through. The original texts stay side by side. Complex comparisons stop after a short timeout.

Supported inputs and limits

50,000 characters per side; comparison runs in a terminable background worker.

Where is my data processed?

In your browser. Cloud saving is optional: only the supported inputs, settings or files you explicitly choose are uploaded. Download or save anything you want to keep before closing the page. Read our privacy details.
