Why Compare Text?

Text diff shows what changed between two versions. Essential for code reviews, document revisions, and comparing contract versions. The diff algorithm finds the smallest set of changes to transform one text to another.

Example: You sent a contract to a client, they made edits, and sent it back. Instead of reading both versions line-by-line, diff highlights only the changes. Or in code review, you see exactly which lines a developer modified without reading unchanged code.

Use cases: Comparing document versions, code review before merging, detecting unauthorized changes to content, tracking content edits over time, debugging why two similar texts behave differently, and verifying translations against originals.

Privacy & Security

All text comparison happens locally in your browser. Both texts are never uploaded to servers, stored, or logged. The diff algorithm runs in JavaScript, keeping your data completely private.
