About This Tool
Text Difference Checker is a free tool for comparing two pieces of text and finding revisions quickly. It clearly separates added, removed, changed, and matching lines, making it useful for edited documents, email drafts, quotations, proposals, contracts, terms, configuration data, and short code snippets. You can compare line by line or highlight changes within modified lines. Optional settings let you ignore leading and trailing spaces, blank lines, or letter case when those differences are not important. The summary shows counts for each result type and an overall difference rate. Everything is processed locally in your browser, so the text you paste is not sent to or stored on the ToolGarage server. For contracts and other important documents, use the result as a review aid and always confirm the original files as well.
