About the Text Diff Checker
Spotting what changed between two pieces of text — a config before and after an edit, two log excerpts, two drafts — is tedious by eye. A diff checker computes the minimal set of line changes and color-codes them: green for added lines, red for removed ones.
The comparison runs locally, so even confidential text stays private. It is perfect for quick comparisons when you don't want to commit files to version control just to see a diff.
