What it does
Styled as you type
Markers like **, _ and [](…) stay hidden until your cursor reaches them.
Fast
A cold open takes about 340 ms, on par with Sublime Text 4, at 0.5 MB against Sublime's 112 MB.
Local only
It runs in the App Sandbox with no network entitlement. There's no telemetry, no updater and no account.
Plays well with git
It autosaves, and reloads when git or another editor changes the file. It can be your default app for .md files.
