Documents
Document Diff Checker
Paste two drafts or open text files. One comparison lines them up and marks added, removed, and changed lines. Use it for a document draft, a config file, or a changelog. Trailing spaces can be ignored. The texts are not stored.
Text
Side by side
Original and revised lines stay aligned, with line numbers on each side.
Added, removed, changed
A removed line paired with the new line beside it is marked as changed.
Drafts and configs
Paste text or open a .txt, Markdown, JSON, YAML, or log file on either side.
