Text Difference Checker inputs

A little guidance.

Compare two pieces of text line by line using a longest-common-subsequence comparison. A minus marks a removed line and a plus marks an added line. Limited to 500 lines and 100,000 characters per input.

How it works

  1. Enter your values, or use the example to get started.
  2. Select “Compare text” to process your input in your browser.
  3. Review the result, then copy or download it when available.

Good to know.

Does it compare individual characters?

This tool compares complete lines. It preserves spaces and letter case so small changes are still reported as changed lines.

Is my input sent to a server?

No. This tool runs in your browser. KILIZU does not upload or store the values or files you enter here.
