About the Text & Code Diff
The Text & Code Diff compares two versions of any text and highlights exactly what changed: added and removed lines, plus the changed words inside modified lines. It is ideal for config files, contracts and code reviews without a Git repository.
Both versions are compared in your browser, so private code and documents never leave your device.
How to use the Text & Code Diff
- Paste the original on the left and the changed version on the right (or open files).
- Switch between side-by-side and unified views, and ignore whitespace or case if needed.
- Copy or download the result as a unified .diff file.
Frequently asked questions
Is my text uploaded?
No. The comparison runs entirely in your browser, so private code and documents stay on your device.
Can I create a patch file?
Yes. Download the unified diff; it uses the standard format that git apply and patch understand.
