What it's good for

Contracts and documents: paste two versions and see every word that was changed. For PDFs, use the PDF Compare tool.
Lists and spreadsheets: find which rows were added or removed between two exports.
Code and settings files: download the result as a standard .diff patch that works with git apply and patch.

Files up to 20 MB open straight into the boxes: TXT, CSV, HTML, JSON, XML, Markdown, code and subtitles.
