Frequently asked questions
What is the difference between line and word diff?
Line diff compares whole lines (ideal for code), word diff highlights individual changed words within a line.
How do I ignore whitespace?
Enable the option to ignore spaces/indentation so pure formatting changes are not shown as differences.
What does unified vs side-by-side mean?
Unified shows both versions stacked with +/- markers, side-by-side places them next to each other.
Are my texts uploaded?
No, the comparison runs locally in the browser; your texts do not leave the page.
