How to Use the Diff Checker

Original on the left, modified on the right (or swap anytime).

Side by side for a clear split, or unified for a compact +/− list.

Green = added, red = removed. Stats summarize how much changed.

Is this diff checker free?

Yes. Compare text on Site95 free with no signup and no limits.

Is my text uploaded?

No. The entire comparison runs in your browser. Site95 never receives your text.

What is a side-by-side vs unified diff?

Side-by-side shows Original and Modified in two columns. Unified stacks changes in one list with + / − markers, like many code tools.

Can I ignore spaces or letter case?

Yes. Use Ignore whitespace and Ignore case before comparing if you only care about real wording changes.

Does it work for code?

Yes. Paste any plain text or code. It compares line by line and highlights what was added, removed, or changed.
