Questions fréquentes

Is it a line diff or a character diff?

This tool does a line-by-line diff using the Myers algorithm. That's the standard for git and most code review tools.

Does it handle very large files?

Yes - up to your browser's memory. Files over a few megabytes may take a second or two to render.

Is my text uploaded anywhere?

Never. Diffing runs entirely in your browser. Neither version leaves your device.

Can I export the diff?

Copy the highlighted output as plain text - the +/- prefixes match unified-diff format for pasting into commits or reviews.
