Everything in the box
A complete markdown workflow. Edit locally, preview in the browser, export and share — from any machine, any shell.
CLI bridge
Run one command, connect your local folder to the web editor. Edits sync bidirectionally over WebSocket — change a file locally and the browser updates instantly, edit in the browser and the file saves to disk.
Works everywhere Node.js runs — SSH, Termux on Android, CI runners, Raspberry Pi. No daemon, no config file, no desktop app required.
Live preview
Side-by-side editor and preview with scroll sync. Mermaid and D2 diagrams render inline as you type. Toggle between split view, editor-only, and preview-only layouts.
Scroll sync keeps your position aligned between editor and preview pane — even in long documents with diagrams.
Publication-quality PDF export
Generate beautiful, print-ready PDFs powered by Pandoc and Typst. No headless browser, no wkhtmltopdf — just clean typographic output with proper page breaks, headers, and table of contents.
Mermaid and D2 diagrams are pre-rendered server-side and embedded as crisp vector graphics. Async export pipeline means large documents with complex diagrams export without blocking. HTML export also available.
Share links
Generate a share link for any document. Optionally set a password or restrict to read-only. Recipients see a polished rendered view, not raw markdown.
Token-based auth with bcrypt-hashed passwords. Read-write shares let collaborators edit directly.
GitHub integration
Connect GitHub repos, browse files with ghost items that lazy-load on demand, edit in the web editor, and submit PRs — all without cloning.
OAuth-based, tokens encrypted at rest. Ghost items keep large repos fast by loading content only when you open a file.
Collections
Group documents from different sources into collections. Create a curated set of docs for a project, a team, or a topic — regardless of where the files live.
Hierarchical items, drag-to-reorder, full-text search across all your documents and collections.
Diagrams
Mermaid.js renders client-side for instant feedback. D2 renders server-side with ETS caching for fast repeat views. Both render inline in the preview.
Security-level "strict" on Mermaid. D2 runs via CLI with semaphore-limited concurrency and timeouts.
CodeMirror 6 editor
Syntax highlighting, vim mode, keyboard-driven command palette, cheatsheet overlay, toolbar, and full-text search. No save button, no tabs — autosave and autosync by design.
Immersive mode for distraction-free writing: fullscreen, typewriter scrolling, paragraph focus. 7 themes, 10 fonts, fully customizable.
