Text Diff compares an original and a changed version and marks what was added and removed. You can copy the result as a unified patch or download it as a .patch file.
Use it to check what changed between two drafts of a policy, a cover letter, or a config snippet. A moved paragraph can show up as a delete plus an insert. Whitespace-only changes can look noisy, so normalize line endings if the result looks messy.
Both texts stay in this tab. Refreshing clears the boxes. There is no account history, so copy the version you want to keep.
