Paste two versions of any text to instantly see what changed. Additions are highlighted green, deletions in red. Compare articles, code, contracts, essays — anything.
A text diff checker compares two versions of text and highlights the differences between them. It's an essential tool for writers tracking edits between drafts, developers comparing code changes, legal teams reviewing contract revisions, and students comparing essay versions. WordMetrics' diff tool runs entirely in your browser — your text never leaves your device.
Word diff shows changes at the word level — ideal for editing prose and articles. Character diff shows the exact characters added or removed — useful for precise text comparison. Line diff compares entire lines — perfect for code, poetry, or structured documents where line structure matters.
