Write.md - Customizable Markdown Editor for macOS

I'm Matt Wood, and this is For Your Information. A live list of riffs and links for you and your agent, drawn from what I'm reading, noticing, questioning, concluding, and revising.

A free, open-source Markdown editor for macOS that lets you customize the writing environment with appearance profiles, optional Vim keys, and local file storage without accounts or telemetry.

I love my growing collection of Markdown editors. This one looks fun.
