MRDown

什麼是 MRDown？

MRDown is a macOS-native Markdown editor for a world where AI agents edit your files. When an agent rewrites your Markdown, it shows exactly what changed — as a diff — instead of silently swallowing it. Touch the same lines as the AI and you get a 3-way view: you choose what stays, and the agent's version lands in history as an external rewrite, not the truth. See how a doc changed over time, compare any two files with ⌘⇧D, and pick up where you left off. Free, MIT-licensed, and truly native.
