For Claude · ChatGPT · Cursor
A lightweight, cross-platform Markdown viewer that re-renders as your AI
writes. No vault. No setup. Double-click a .md file and read it.
Use Tauri 2 with comrak on the Rust side and Svelte 5 on the frontend.
Watch the file with notify debounced at 150ms.
The render pipeline preserves scroll position across re-renders, so the user never gets yanked away while their AI is writing.
Open a file, run Claude in another terminal, watch content appear. Smart-scroll follows the edit only if you're nearby — no yanking.
Drop multiple files to open as tabs. Drag a tab outside the window — Chrome-style — to spawn a new window.
Files browser and document outline in a Lightroom-style stack. Each toggles independently. Drag to resize.
All five alert types, tables with alignment, task lists, footnotes, KaTeX math, Mermaid diagrams, syntax-highlighted code.
Tauri 2 + WebView2 means no Chromium bundle. Installer is small. Cold start under a second.
Every action has a shortcut. Ctrl+T new tab. Ctrl+W close. Ctrl+] / Ctrl+[ width. Ctrl+\\ full-width. Ctrl+E split.
No network calls. No telemetry. No accounts. Files stay where they are. Open-source under MIT.
Auto-follows system. Apple-leaning palette tuned for long reads. Adjustable zoom, font size, and content width.
Trust modal. Folder pick. Right-click. Open preview. Three of your screen taken by sidebars you can't reshape. Markdown deserves better.
Single file? Casual reading? You'd still need to set up a vault and a plugin to make it pretty. md-reader is stateless — open a file, you're done.
Marky, MarkViewer, MacMD Viewer all launched 2025–2026 to view AI output. None of them ship for Windows. md-reader fills that gap.
MarkText is unmaintained. Boost Note shut down Sept 2025. Typora went paid. Mou is dead. The viewer-first niche needs a new entrant.
Or build from source: git clone … && npm install && npm run tauri build
