The Text Diff tool compares two pieces of text and highlights exactly what changed between them. Paste an original version on the left and a modified version on the right, and the tool computes a line-by-line difference: added lines are shown in green, removed lines in red, and unchanged lines in neutral, with running totals of additions and removals. It is invaluable for reviewing edits to documents, comparing configuration files, spotting changes in code snippets, or checking what a colleague altered. Everything is processed locally in your browser, so even sensitive text never leaves your device.
