Show HN: Building a Markdown editor for Mac, iOS and web

Beauty is a local Markdown editor that runs on Mac, iPhone, and in the browser, offering real-time rendering of Markdown text, tables, math, and diagrams. It's designed for a distraction-free writing experience and allows syncing of notes through peer-to-peer WebRTC. The editor is free, with optional iCloud syncing through a subscription. The code is not open-sourced yet but will be in the future.
