About This Tool
This text diff tool helps you quickly find subtle differences between two pieces of text. It offers two classic comparison views: "side-by-side" and "unified", and supports precise highlighting at both line and word levels. You can choose to ignore whitespace or case differences for more accurate results. The tool supports synchronized scrolling and one-click text swapping, with all processing being fully localized.
