PlanWatch

PlanWatch keeps an eye on the Markdown files that matter to you and shows every change the moment it lands. Point it at your project notes, plans, or docs — any Markdown file that gets rewritten while you work, whether by a build script, a background process, or an AI coding agent — and PlanWatch renders each update live, scrolling and highlighting the exact section that changed. MONITOR MODE • Live, debounced rendering as files change on disk • Smooth partial re-render — only the section that changed updates • Automatic scroll and highlight to the latest change • Native notifications when a file changes while you're away EDIT MODE • Split editor: Markdown source on one side, live preview on the other • Full formatting toolbar — headings, bold, italic, lists, task lists, quotes, code, tables, and links • Your edits merge safely with changes made to the file underneath you MAC, iPAD & iPHONE • Your Mac holds the files and streams changes to iPad and iPhone over the local network • Watch and read along from the device sitting next to you while your Mac does the work • Nothing leaves your machine — no account, no cloud, no tracking Built natively for macOS and iOS. Fast, private, and out of your way.
