FAQ

It uses a longest-common-subsequence algorithm written specifically for this tool, comparing word by word rather than character by character for readable results.

Yes, though the diff is word-based. For source files, comparing line by line in your editor may be clearer.

Runs of whitespace are normalised during comparison so that reformatting alone does not appear as a change.

Very large texts take longer because the algorithm compares every token pair, but typical documents are instant.

No. Both texts stay in your browser.

About this tool: Text Diff Checker

Spot every change between two texts

The Text Diff tool compares two versions of text and highlights exactly what changed — added lines in one colour, removed lines in another, changed segments inline. Paste both versions, and the differences appear instantly, character-precise.

Proofreading a revision against its original, checking what a colleague changed in shared copy, or verifying that a translation preserved every sentence — visual comparison catches what eyes miss. Contract revisions benefit especially: the diff shows precisely which clauses moved, changed or disappeared.

Comparison runs entirely in your browser — confidential drafts never leave your device. Switch between line-level and character-level views depending on whether you care about structure or wording, and copy a change report when you need to summarise the edits.

Like every Piclizer tool, this one runs entirely in your browser — your files stay on your device.
