About Text Diff Tool
Text diff algorithms identify the minimum set of changes between two text versions. They power Git, code review tools, and document collaboration platforms. Line-by-line diff shows added (green), removed (red), and unchanged lines. Character-level diff precisely marks which words changed within a line -- ideal for catching subtle text modifications. All comparisons run locally; no data is uploaded.
