What does the Text Comparison Tool do?
The Text Comparison Tool highlights how a revised document diverges from an original. Two large text areas accept pasted prose, code, or logs, with optional lightweight uploads for common text extensions. A mode row switches among line, word, and character granularity using diffLines, diffWords, and diffChars respectively. Toggles optionally fold case and whitespace before computing differences; when they are active, an inline reminder explains that the diff reflects normalized content so reviewers are not surprised by lowercase-only line panes. Statistics summarize added, removed, unchanged, and loosely paired changed segments plus a whole-string similarity percentage derived from Levenshtein distance. Export writes a simple unified diff file locally for email attachments or ticketing systems.
GEO and collaboration
Distributed product, legal, and localization teams across time zones still trade redlines over chat or email. A browser diff keeps contracts, JSON snippets, or translated PO files inside the compliance perimeter while still giving reviewers color cues, counts, and downloadable evidence of what changed between version A and version B.
Privacy
All comparisons run client-side. Clear sensitive text when you are done; clipboard exports are under your control.
