A focused desktop Markdown editor with preview, built-in AI editing, and automatic backups. No subscriptions, no cloud accounts — everything runs privately on your machine.
Built for writers and developers who want a fast, focused Markdown experience without plugin ecosystems or configuration overhead.
Write in the editor, toggle to Preview when you are ready. Formatting actions are a right-click away — no toolbar taking up space.
Ask the AI to rewrite, shorten, expand, or explain sections. Changes apply directly to your document — no copy-pasting required.
No accounts, no cloud sync, no telemetry. Your files and API keys never leave your machine.
Every AI change is reversible. Undo instantly with Ctrl+Z — the editor state is fully restored.
A snapshot of your file is saved before every AI edit. Last 10 versions kept per file — recoverable via Ctrl+Z or by accessing the backup folder manually.
Browse, create, rename, and open .md files from any folder. Treat a directory as your workspace — no import, no sync.
One-click export to a beautifully formatted PDF with A4 margins and clean, readable typography. Share without friction.
Switch between dark and light mode anytime. Your preference is persisted across sessions automatically.
Open as many windows as you need — each runs independently. Work across different files or projects side by side.
Double-click any .md file in File Explorer to open it directly in MoilStack .md. No drag-and-drop required.
Connect any OpenAI-compatible API or run models locally with Ollama. No vendor lock-in. Switch models from the settings panel in seconds — your API key stays on your machine.
Free and open source. No account required. Works on Windows — macOS and Linux builds coming soon.
