Capability overview
What does language-aware code comparison do in Diff Anything?
Detect code from filenames, extensions, shebangs, and pasted content, then keep syntax highlighting, moved blocks, wrapping, and compact context visible in desktop and terminal diffs.
Shared extensions are disambiguated from content, and framework files can highlight embedded implementation languages instead of falling back to plain text.
The CLI provides a Unicode-safe highlighted terminal view with automatic or forced colour, an explicit language override, and configurable context around each hunk.

In the workflow
Select a mode
Use automatic detection or explicitly choose text, structured, folder, archive, document, image, binary, or API comparison.
Diff Anything keeps the source pair, selected mode, comparison rules, result, and review state together so the same decision can be revisited or automated.
Useful in practice

Choose the right comparison mode
Choose sources, understand automatic detection, and select the engine that answers the question you are actually asking.
The guide covers start with the review question, choose and load sources, how automatic mode resolves, read text and structured results, keep code readable, navigate and review, resolve a three-way merge, recover from input problems. It is the best next step when you want to move from the product overview into a repeatable setup.

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.
