TEXT DIFF
See exactly what changed between two texts.
Edit both sides, compare them locally, and review the result as a unified diff or side by side.
Download for Mac
Free download. Requires macOS 14 or later.
WHAT IT HELPS WITH
Review a change without setting up a repository.
Choose the useful view
Read changes in a unified view or side by side. Hide the editors when you want more room, then copy the diff or a short summary.
Choose the right detail
Use Line for code-review changes, Word for prose, JSON, or logs, and Character for punctuation, identifiers, spacing, or short values. Ignore whitespace or letter case when those differences do not matter.
CLEAR BOUNDARIES
Text comparison, kept focused.
Text Diff compares the two text sources you provide. It does not compare folders or repositories, apply patches, or treat JSON as a special semantic format.
For larger inputs, Compare is an explicit action so editing stays responsive.
