Text Comparison Tool

Compare two texts in the browser with the diff library: side-by-side line view or inline word/character highlights, optional ignore case and whitespace (diff runs on normalized text with an on-page note), file upload per side, swap, live added/removed/unchanged-style stats plus Levenshtein similarity, show-unchanged filter for lines, and copy or export a unified diff .txt.

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.

Frequently Asked Questions

Why do line colors look lowercased when Ignore case is on?

The diff engine compares normalized strings so subtle case-only edits surface; the UI reminds you that the visible line text reflects that normalized comparison path.

Can I diff huge logs?

Very large inputs may slow the browser; consider trimming to the relevant region first for smoother scrolling.

Is the Text Comparison Tool free?

Yes for typical personal and work use on Dynamic Duniya.
