Features

Side-by-Side View

Two-column layout shows original and modified texts in parallel — added lines in green, removed in red — making it easy to trace every change.

Unified Diff View

Classic unified diff format with + and − markers per line, styled in the DiffX design. Perfect for copying or sharing as a patch-style report.

Line, Word & Char Diff

Three granularity levels: Line diff for overall structure, Word diff for inline changes within lines, and Char diff for character-level precision.

All Languages + RTL/LTR

Handles Arabic, English, Chinese, Hebrew, Japanese, and all Unicode scripts. RTL/LTR toggle adapts the display direction for any language.

Ignore Case & Whitespace

Toggle case-insensitive comparison to ignore capitalisation differences. Toggle whitespace to skip leading/trailing space and collapsed space differences.

Similarity Score

Calculates a percentage similarity between the two texts based on the number of matching vs differing lines — at a glance you know how close the two versions are.
