What is Text Compare?

A text comparison (diff) tool helps identify precise differences between two documents or snippets. It's invaluable for reviewing code revisions, comparing draft documents, proofreading, and spotting duplicate lines or spelling updates.

This tool utilizes a client-side LCS-based highlighting algorithm to instantly mark deleted text in red and added text in green, right in your browser.
