Comment Fonctionne cet Utilitaire

A visual text and code diff comparison utility powered by the Myers diff algorithm. Compare two documents side-by-side (split view) or inline (unified view) with line-by-line, word-by-word, or character-by-character granularity. Features whitespace-ignoring toggles, line addition/removal metrics, and instant clipboard sharing.

Foire Aux Questions

Is my text private when checking differences?

Yes, 100%. The diff algorithm executes entirely inside your browser memory. No code or text snippets ever touch any remote server.

What is the difference between Split and Unified view?

Split view places the original and modified documents side-by-side with synchronized lines. Unified view displays all changes in a single linear stream with + and - indicators, similar to GitHub and Git diffs.

Can it ignore formatting and whitespace changes?

Yes! Toggle the "Ignore Whitespace" option to ignore differences in spaces, tabs, and indentation.

Compare & Diff Two Text Files in Terminal
