What it renders

Everything below is GitHub Flavored Markdown, plus the two things technical writing always ends up needing.

math.md

Inline $E = mc^2$ and display:

$$
\sum_{n=1}^{\infty} \frac{1}{n^2} = \frac{\pi^2}{6}
$$

Inline E = mc2 and display:

n=1 1/n2 = π2/6

Built like a Mac app, not a browser tab

It opens documents, not projects. Everything you already know how to do works the way you expect.

Tabs and windows
A document per window, merged into native tabs when you want them.
Quick Look
Select a .md file in Finder, press space, read it rendered.
Scroll sync
The editor and the preview follow each other, both ways.
Reloads on change
Edit the file elsewhere and the open document catches up.
Find and replace
Across source and preview together, with regular expressions.
Nothing leaves the machine
Parser, highlighter, math and diagrams all ship inside the app.
Markdown Prism showing Markdown source with line numbers beside the rendered document
Line numbers, syntax highlighting, live preview.
