Direct answer
How does Diff Anything compare source code?
Diff Anything keeps source comparison lossless and line-based while detecting the presentation language from an override, filename, extension, content marker, or shebang. The desktop and terminal views add syntax highlighting, moved-block cues, wrapping, compact context, navigation, and save controls without claiming an abstract-syntax-tree comparison.

Do compared files leave the computer?
No. Comparison is local. The application has no account, cloud comparison service, analytics, or telemetry.
How does automatic mode choose a comparison?
Matching structured formats use their semantic engine, two folders use folder comparison, and other compatible inputs fall back to text. You can always choose a concrete mode.
