Free Diff Checker — Compare Two Texts Online

Text A Text B Diff

How to use

Compare two versions of text or code quickly.

How does the diff work?

We use a line-by-line or character diff to show what was added, removed, or changed between the two texts.

Can I compare code?

Yes. Paste code or any text in both boxes. For large files, consider splitting or using a local diff tool.

Is my text stored?

No. Both inputs are only used to generate the diff and are not saved.
