About Text Compare Tool

Text Compare Tool is a free, fast, and simple online tool for comparing two pieces of text and highlighting the differences between them.

Whether you're a developer comparing code snippets, a writer comparing document versions, or a student checking for changes — our tool gives you instant, clear visual diff results.

How It Works

We use the Longest Common Subsequence (LCS) algorithm to compare your texts word by word. Words that were added appear in green, and words that were removed appear in red. Unchanged words have no highlight.

Privacy

Your text is never stored. Comparisons are processed in real time and discarded immediately after the result is returned. See our Privacy Policy for details.

Technology

Built with Laravel 11, Tailwind CSS, and plain JavaScript — no heavy frameworks, just fast and reliable code.
