Online Text Diff Tool
Compare two texts and see exactly what changed, line by line.
Paste two versions of a document, code snippet, or any text and instantly see what changed. Added lines are highlighted in green, removed lines in red — just like a git diff, but in your browser with no setup.
Why This Diff Tool Stands Out
Color-Coded Changes
Green for additions, red for deletions — changes are unmissable.
Line-by-Line View
See exactly which lines were added, removed, or modified.
Client-Side Only
Your text is never uploaded — comparison runs entirely in the browser.
No Registration
Open and compare — no account, no waiting.
How to Compare Two Texts
- Paste the original text in the left panel.
- Paste the modified text in the right panel.
- The differences are highlighted automatically below.
