For developers

The Markdown editor that speaks code

Write READMEs, docs, and dev blog posts with syntax-highlighted snippets, diagrams-as-code, and one-click publishing to the platforms developers actually read.

Code-first writing

Code blocks that are treated like code

READMEs, changelogs, and tutorials live or die by their snippets. Write fenced code blocks with syntax highlighting, then embed them as GitHub gists or shareable screenshots without leaving the editor.

  • Fenced code blocks with syntax highlighting in editor and preview
  • Embed snippets as GitHub gists or polished code screenshots
  • Markdown linting with one-click fixes, GFM tables, and task lists

Diagrams as code

Architecture diagrams that live in your Markdown

Describe flowcharts, sequence diagrams, and system maps in plain text and see them render live. Diagrams stay in your document, so they get reviewed and versioned like the rest of your code.

  • Mermaid flowcharts, sequence diagrams, Gantt charts, and more
  • Graphviz and mind map rendering with live preview
  • Plain-text sources that diff cleanly in code review

AI on your terms

An AI assistant that speaks fluent code block

Draft, refactor, and explain technical content with an assistant that understands the document you have open. Every suggestion lands as a diff preview you accept or reject.

  • Generate code snippets and diagrams straight from a prompt
  • Bring your own key: OpenAI, Anthropic, Grok, or Gemini
  • Run fully local models via Ollama in the desktop app - nothing leaves your machine

Publish anywhere

Publish where developers actually read

Connect a destination once in Settings, then push the same document to your blog platforms or straight into your own infrastructure. Your Markdown stays the canonical source.

  • Publish to DEV (Forem), Hashnode, WordPress, Ghost, or X Articles
  • Push to a GitHub repository, a Gist, or your own S3 bucket
  • Custom frontmatter support for Hugo, Jekyll, and static-site workflows

Reliable by default

Drafts that survive flaky Wi-Fi and bad merges

The editor is offline-first, so writing works on planes and trains, and every change is captured in automatic version history you can restore in one click.

  • Offline-first editing that syncs when you reconnect
  • Automatic version history with instant restore
  • Import and export plain Markdown - your files stay yours
