DiffNote

Write two texts side by side and see every difference highlighted. Great for drafts, contracts, and config files. iPhone, iPad, and Mac with iCloud sync.

DiffNote is a note app that puts two texts side by side and shows you what changed, at a glance.

Use it to compare drafts and revisions, two versions of a manuscript, or config files and code.

SIDE-BY-SIDE EDITING • Edit in two panes, left and right or top and bottom • Changed lines are highlighted as you type (added, removed, changed) • Synchronized scrolling between panes

COMPARE VIEW • See every line with its differences • Tap a line to see character-level changes • Counts of added, removed, and changed lines • Jump to the previous or next difference • Pinch to zoom (scroll-wheel zoom on Mac)

COMPARE OPTIONS • Ignore whitespace • Ignore letter case

FILES • Import text files, including by drag and drop • Supports non-UTF-8 encodings such as Shift_JIS • Save each side as a text file • Share both sides together
