Hey Product Hunt 👋 AI agents now write more of the first draft. Humans still need to review the diff. That idea was the starting point for RibbonDiff. I wanted a fast, Mac-native place to compare two versions of text side by side without a browser tab or a heavyweight merge tool. RibbonDiff gives you: • two fully editable panes • live diff updates as you type, paste, or open files • a visual center ribbon that keeps matching change blocks connected • per-pane Find, line numbers, wrap, themes, and code-editor niceties • Pro workflows for Open / Drag & Drop / Save / Save As • opening two files directly from Terminal or Finder It works well for code snippets, AI-generated edits, config files, logs, and document revisions. RibbonDiff is free to download in Limited mode for pasted/typed text. Pro unlocks file workflows with a 7-day trial and a $3.99 lifetime purchase. No subscription. I’d love feedback on two things: 1. Where does your current diff workflow break today? 2. What would make a Mac diff app feel indispensable in your daily review loop?
