Text Diff Checker
Compare two texts and see added, removed and changed lines highlighted.
See what changed between two versions
Comparing a new contract version, an article back from the editor, two configuration files or versions of a code snippet line by line takes time and is error-prone.
How it works
Paste the original text on the left and the new text on the right. The tool aligns both versions and marks added lines in green and removed lines in red, so you see every change at a glance.
Privacy
Comparison happens entirely in your browser. Confidential contracts, source code and personal documents are never sent to a server.
How to use Text Diff Checker
- Paste the original text into the first box.
- Paste the changed text into the second box.
- Differences are highlighted in colour.
- Review the added and removed lines.
Why use this tool?
A fast, secure comparison tool for lawyers, editors, translators and developers.
FAQ
Is there a size limit?
Comparison runs in your browser; very large texts (thousands of lines) may take a few seconds on slow devices.
Can I compare Word documents?
Copy the text of each document and paste it into the boxes.
Does it show word-level differences?
It works line by line; changed lines are shown as removed and added.
