Frequently asked questions
Is my text uploaded to the server?
No. All diffing and file parsing is done client-side in your browser.
Which file formats are supported?
Plain text files (.txt), and source files (.js, .py, .html) - any text-based file.
How do I share results?
Use the Share button - it creates a URL that encodes your inputs so others can reproduce the comparison.
