A native macOS reader and editor for the markdown already on your disk. Point ML-42 at any folder — a git repo, a docs directory, an Obsidian vault — and read, search, and edit across projects. No import, no database; files stay where they are. Cmd+K searches every project at once. When an AI agent rewrites a file, ML-42 reloads it in place. On-device summaries via Apple Intelligence. Sandboxed — no network, no telemetry. $12.99, buy once. Mac, no subscription.
Does the Cmd+K search index live anywhere on disk, or does it rebuild each launch? Curious how that scales when pointing it at a large Obsidian vault with years of notes.
@mahirgkcenrxmi you add projects (folders) and the app indexes the files there and updates as they change. We tested it with very large projects. Happy to send you a code to try it out and let us know how it works for you.
Hey Product Hunt — ML-42 is a native Mac reader and editor for the markdown you already have. You point it at any folder — a git repo, a docs directory, an Obsidian vault — and it reads and edits what's there.
No import, no database, no vault to adopt. The folders you open become part of your the library and stay put at the same time. We built it because our own markdown lives in a dozen places: the Claude.md that steers an agent, the specs that say what to build, the decision records, your entire context. Every reader we tried wanted us to herd those files into its own home first.
ML-42 opens them where they are and keeps them there.
Three things it does well:
Browse like a browser. Open a folder, see documents as cards with excerpts and dates, click in, hit back. Cmd+K searches every project at once.
Render fast, edit raw fast. Preview is instant — headings, code, tables, front matter. Flip to raw with a keystroke and back.
Reload what your AI rewrote. When an agent edits a file while you're reading it, ML-42 reloads it in place — no refresh, no stale copy.
Each document also gets a short on-device summary from Apple Intelligence. Sandboxed; nothing leaves the machine.
$12.99, one time. Mac only, no subscription. We make money when you buy it, not by hosting your files. Privacy first. ML-42 is the second entry in the Field Bureau + Werkstatt Markdown Suite.
