VAYS MD READER · For Mac
A native macOS Markdown viewer and editor for the .md files piling up in your repos — CLAUDE.md, READMEs, specs, transcripts, plans. Real typography instead of source code. No Electron, no cloud — nothing ever leaves your Mac.
Coding agents like Claude Code produce Markdown constantly: CLAUDE.md instructions, README files, migration plans, research notes, meeting transcripts. Code editors show them as raw source; browser-based tools ship an entire Chromium to display a text file. VAYS MD Reader is the missing piece — a fast, native macOS app whose only job is making Markdown a pleasure to read and easy to edit.
It renders GitHub Flavored Markdown the way GitHub does — tables, task lists, strikethrough, autolinks — and keeps going where most viewers stop: callout cards, footnotes, YAML front matter as a metadata card, shields.io badges drawn natively, LaTeX math typeset without a web view, and Mermaid diagrams rendered by an engine that ships inside the app, fully offline.
Free viewers show you the file. Editors want to own your notes. VAYS MD Reader sits exactly where AI-era work happens: reading first, editing when needed, everything local.

Open a document and let Claude Code keep writing — the reader re-renders on every save. One copy-paste hook auto-opens every .md your agents write, and each file lands in the From Claude inbox: grouped by project and session, unread until you look, provenance on hover. Five parallel sessions stay five tidy threads. When the plan is ready, copy it as rich text straight into an email.
Part of the VAYS family — record a memo in VAYS, read the transcript in VAYS MD Reader; the inbox connects with one click. Same private-AI foundation, same rule: everything stays on your device.

In a viewer made for it. VAYS MD Reader renders .md with real typography — and its QuickLook extension means the space bar previews any Markdown file straight in Finder, before you even open the app.
Yes — the engine is bundled inside the app. Flowcharts, sequence diagrams, gantt, mindmaps: all render with zero network access. You can also draw flowcharts and sequence diagrams visually and the source is generated for you.
That's what it was built for. A copy-paste hook opens every .md your agents write, the From Claude inbox groups arrivals by project and session, and open documents re-render on every save — you watch the agent write in real time. Full-text search covers every repository in your library.
Completely. No account, no analytics, no cloud, zero network requests. Files stay as plain .md on your disk — remove a folder from the library and the app never sees it again.
Yes. Highlights, comments and snippets live in a sidecar next to the document — the .md itself is never modified. Annotations survive agent rewrites thanks to smart text anchoring, and you can copy them all as a Markdown digest.
Ask Document connects to Ollama running on your Mac: chat with the open file, or quote a fragment and ask about exactly that — fully offline, no API keys, no cloud. If you don't use Ollama, the app simply makes zero network requests, ever.
On the Mac App Store now. One price, no subscription, private forever.
