A lightweight, project-oriented Markdown editor that renders with proper chat interface styling. Browse all your .md files, write and edit your notes, then paste into your LLM chat or terminal without any formatting surprises.

Download the latest version (Windows and Ubuntu 24.04 confirmed working; macOS DMG built but untested)

I built this because I keep a lot of Markdown files around for projects using LLM and couldn't find an editor that wasn't either too heavy or too bare-bones.

Project sidebar: Pin folders and browse your .md files in a collapsible tree. Filesystem changes are watched in real-time, so it stays in sync without you doing anything.

Lightweight: Built on Tauri v2 using the system's native WebView instead of bundling Chromium like Electron does. The portable exe is ~11 MB, the installer under 3 MB.

Rendering: The preview pane is modeled after Claude's chat interface -- similar typography, code blocks, spacing, the works.

• Split-pane live preview with drag-to-reorder tabs
• Formatting toolbar
• Scroll sync
• HTML and PDF export
• Autosave with crash recovery, atomic file writes
• Single-instance: double-clicking a .md file in your file manager opens it in the running window instead of spawning a second one
• Find & replace with in-editor match highlighting, syntax highlighting, dark mode, external file change detection, portable mode, auto-update checker
• Keyboard focus rings and prefers-reduced-motion support

No npm, no node_modules, no build step for the frontend.

You'll need Rust and the Tauri CLI.

cargo install tauri-cli --version "^2"
cd src-tauri
cargo tauri build

On Linux, you'll also need: libwebkit2gtk-4.1-dev libappindicator3-dev librsvg2-dev patchelf.
