Three simple steps to find every difference between your texts.
TextCompare is used by thousands of professionals every day.
Text comparison is a fundamental task for anyone who works with written content. Whether you're a software developer comparing code files, a writer reviewing edits to an article, a legal professional verifying contract changes, or a student checking revisions — having a reliable text comparison tool is essential.
TextCompare is designed to be the simplest, fastest, and most private text comparison tool available online. Unlike other tools that require sign-ups, downloads, or send your data to remote servers, TextCompare runs entirely in your browser.
Our tool uses a character-level comparison algorithm to identify every difference between two pieces of text. Simply paste your original text on the left, the modified version on the right, and click "Compare!" The results appear instantly, with each difference clearly highlighted at the exact character where the change occurs.
Before comparing, you can transform your text using our built-in editing tools. Convert text to lowercase for case-insensitive comparison, sort lines alphabetically, replace line breaks with spaces, remove excess whitespace, trim each line, or remove empty lines.
Text comparison tools are used across virtually every industry. Developers use them for code reviews and merge conflict resolution. Writers and editors use them to track changes between document versions. Legal teams compare contract drafts. Quality assurance teams verify content accuracy.
