Markdown is plain text, it fits writing, notes and documents, and any app can open it. loomark gives it a quiet home: your text and a file list, no toolbar and nothing to configure, and tabs only when you want them. Whatever writes the file, the editor always shows the newest content.
loomark began with a simple wish: everyone should have a free, beautiful, capable Markdown editor on their computer.
Open source and free forever. Staying in sync with the file is one of our differences, but the first promise is simpler: Markdown should be available to everyone.
Every app can open it, and every tool can read it.
No buttons to hunt for: ## is a heading, - is a list.
Your files stay on your computer, and no service can take them away.
Type Markdown and see rich text directly. No split-pane preview, nothing to learn.
When the file changes on disk, whether by an AI agent, a script or another editor, the editor updates right away. No reopening, no manual refresh.
Turn a document into Word, PDF, a self-contained HTML file or a shareable image, with your theme colors kept.
Keep several documents open in one window (⌘T opens a new tab). Each tab holds its own content, undo history and scroll position, and switching never mixes them.
Render Mermaid flowcharts and sequence diagrams right inside the document, with colors that follow your theme.
Browse and switch between the Markdown files in the current folder, and drag the panel to the width you like. Files created by an agent appear automatically.
Never lose your place in a long document: jump between headings, see the current section highlighted, and find or replace inside the document.
Copy content with formatting preserved into WeChat, email and other rich-text editors.
Available for macOS, Windows and Linux, with English and Chinese interfaces. Free and open source.
