What to Include

• Diff bugs: the two texts (or a minimal reproduction), the granularity mode you used (lines / words / chars), the options that were active (trim trailing spaces, ignore case), and what you expected versus what you saw.
• Feature ideas: the workflow you are trying to speed up — a new layout, a different context radius, file drag-and-drop, syntax-aware diffing for a specific language.
• Privacy questions: note that all processing happens locally in your browser; nothing you paste is ever transmitted. See the privacy policy for details.

Before You Write

If the question is about how the tool works, the FAQ on the home page covers the common ground: how to compare two texts, the difference between line, word and character mode, how the Myers algorithm finds the shortest edit script, what the @@ context bands mean, and how split and unified views differ.
