See exactly what changed. Then fix it right there.

Compare anything

• Another open tab, a file on disk, or the saved version of the document you are editing.
• The clipboard, or a selection against the clipboard.
• Whole folders, with files that differ or exist on only one side grouped together.
• Side by side, or as one unified view.

Edit both sides

• When both sides are open documents, edit either one, and the differences update as you type.
• Copy a change from one side to the other with a single click, or copy them all.
• Step from difference to difference with the keyboard.
• Every change is one undo step.

Only the differences that matter

• Ignore whitespace, letter case, blank lines or line endings.
• Highlight changes word by word.
• In folders, skip hidden files, the .git folder and anything in .gitignore.

Share it as a patch

Save any comparison as a patch file, or copy it as a patch to paste into a message or a review.
