What is Text Compare?

Text compare (also called diff checker) is a tool that highlights the differences between two pieces of text. Whether you are a developer reviewing code changes, a writer editing a document, or a lawyer comparing contract versions, a diff tool saves you from hunting for changes manually. SimpleTextDiff uses the industry-standard diff algorithm to show you exactly what was added, removed, or stayed the same.
