## What is DiffNote?

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

ORGANIZE
• Folders
• Pin, duplicate, and lock notes to prevent accidental edits
• Restore notes from the trash
• Sort by date modified, date created, or title
• Move or delete multiple notes at once

IPHONE, IPAD, AND MAC
• Layouts designed for each device
• Optional iCloud sync across your devices
• Choose text size and a monospaced font

PRIVACY
No account required. No data collection, ads, or tracking. Your notes stay on your device and, if you choose, in your own iCloud.
