See what changed between two texts
Paste text on the left and right; added lines show in green, removed lines in red. Use it to compare contract versions, review code changes, or proofread translations — anywhere you need to find "what changed" fast.
Line-level vs character-level
- Line diff: best for paragraphs and code, where line structure is clear.
- Character diff: catches a typo or a single changed digit within one line.
For example, version 1.0.3 vs version 1.0.4 looks like a whole-line change in line mode, but character mode highlights only 3 → 4.
Situations you'll run into
- Invisible differences: spaces, tabs, or line-ending characters differ. If two texts look identical but still diff, suspect hidden whitespace.
- Reordered lines: even with identical content, a different line order shows up as fully changed.
Pasted text is compared in your browser and never sent to a server. For more use cases, see the text diff checker guide.
