Capability overview
How can I use accessible workspace in Diff Anything?
Press Command-Shift-A on a Mac or Control-Shift-A on Windows to turn a comparison into one ordered page: the sources, a summary, and every difference in words with its location, the change, and the original and updated values. Step through differences, search them, mark them reviewed or ignored, add notes, and apply supported changes from the keyboard. On a Mac it opens automatically when VoiceOver is running. It is included in the free plan; three-way merge is not part of it.
Spot meaningful code changes with Smart Diff across 117 editor languages. Switch to Line Diff whenever you want an exact line-by-line review. Both views keep syntax highlighting and editing close at hand. Ignore rules leave timestamps, IDs, comments, or fixed columns out of a text comparison, and Align these lines pairs two lines by hand where the automatic match is not the one you want.
In the workflow
Review and resolve
Navigate stable differences, apply supported changes, or use Pro to resolve three-way conflicts and conflict markers or approve a folder synchronization plan without losing source context.
Diff Anything keeps the source pair, selected mode, comparison rules, result, and review state together so the same decision can be revisited or automated.

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?
Compatible spreadsheet formats can use the shared spreadsheet comparison even when their extensions differ, matching structured formats use their semantic engine, two files in different data formats, such as JSON and TOML, are compared by their data, two folders use folder comparison, an archive beside a folder is compared as the folder it holds, and other compatible inputs fall back to text. You can always choose a concrete mode.
Free & Pro: what’s included
Available on the Mac App Store and Microsoft Store. Free desktop use lets you try every comparison engine for files up to 5 MiB per side and 10 new comparison sessions per local day; collection previews show the first 100 items, binary comparisons the first 100 byte differences, and PDF previews the first 3 pages. Plain text, JSON, and Jupyter notebook comparison are complete, and opening files from Finder or File Explorer, diffanything:// links, and AppleScript are free. The free CLI supports text, JSON, and notebooks, and the command-line helper that brings the CLI to the Mac App Store version is a free download that uses the Pro purchase made in the app. A one-time Pro purchase removes the preview and session limits and unlocks larger sources within technical limits, saved profiles and history, saving folder snapshots, report export and printing, JSON Patch export, applying patches, three-way merge and conflict resolution, the Git merge driver and merge tool, folder synchronization, batch manifests, every CLI mode, and, on Windows, trusted preprocessors.
