Everything Markdown, nothing in the way

✍️

What you see is Markdown

Edit formatted text directly, or switch to the source view at any time. Files are saved as standard Markdown.

🧰

A complete style bar

Headings, highlights, superscript, lists, tasks, tables, links, images and code blocks — one click away, with keyboard shortcuts.

🧮

Beyond basic Markdown

Callouts, footnotes, math, Mermaid diagrams, definition lists, a table of contents, front matter, emoji and wikilinks.

🗂️

Tabs and folders

Open several documents in tabs, browse a folder in the sidebar, and pick up where you left off with Open Recent.

✨

Optional AI help

Continue writing, summarize, improve style, fix grammar or Markdown, or run your own prompt — with the provider and key you choose.

🌗

Made for your Mac

Native, sandboxed and fast. Light, Dark or System appearance, adjustable font size, auto-save, HTML export and printing.
