Markdown Diff

Paste two versions of a document to highlight every addition and deletion, then copy a standard unified diff.

How it works

Step 1

Paste both versions

Put the original on the left and the changed version on the right.

Step 2

Choose granularity

Compare whole lines for structural changes, or words for copy edits.

Step 3

Share the changes

Copy or download a unified diff to attach to a review or apply with git.

Frequently asked questions

Does this work for any text, not just Markdown?

Yes. The comparison is plain text, so it works for any document or code.

What format is the exported diff?

A standard unified diff, the same format produced by git diff and accepted by patch tools.

Are my documents saved?

Both versions are saved in this browser so you can come back to them. Nothing is uploaded.
