mdEdit - Repo

mdEdit is a local-first markdown editor for macOS with a twist: the documents you have open are directly readable and editable by AI over a local MCP connection — no cloud in between, and every AI edit happens right on your screen. It pairs a clean, iA Writer-inspired writing surface with fully native macOS chrome, live preview, and stale-write protection so the AI never clobbers your typing. You can download the notarized app free, or grab the source on GitHub (MIT licensed) and build your own.
