GrayCat Markdown
A local-first sticky Markdown editor for macOS.
A local-first sticky Markdown editor for macOS.
I'm a doctor in a Chinese orthopedic department. Writing is a big part of my day — clinical notes, literature reviews, patient-education drafts, the occasional article for a medical WeChat Official Account. Markdown is how I think: it's fast, portable, and my scribbles don't get locked into any particular vendor's file format.
I tried most of the popular Markdown editors over the years. Each had something I liked and something that got in the way. I wanted a tool that felt like a sticky note on my desktop — always a keystroke away, never demanding I log in, never syncing my drafts to somebody else's server. So I built one.
Zero network requests. No account. No telemetry. Your drafts live on your Mac.
Always-on-top window, menu-bar presence, global hotkey ⌘ Shift M to surface from any app.
Copy with formatting from the preview — paste into Mail, Pages, Lark, Outlook with styles preserved.
Four presets (Standard / Zhihu / Toutiao / WeChat) each with a tuned preview and copy strategy, one Markdown source behind them all.
Click a rendered [ ] checkbox and the source Markdown updates in place.
File associations, right-click menus, menu bar, file dialogs — all native. No web-browser shell feel.
Interface in 简体中文, English, and 日本語. Switchable on the fly.
Paper, Forest, Ink — plus a six-color custom palette for your own preferences.

I also make KneeDaily, a daily-literature iOS app for knee-sports-medicine specialists. Same single-developer policy: every Chinese summary is written and reviewed by me personally.

我是一名骨科医生，在苏州大学附属第二医院关节外科，亚专科是膝关节运动医学。 写字是日常的一部分：病历、文献综述、患者宣教稿、偶尔也给医学公众号写文章。 Markdown 是我的思考方式 —— 快、跨平台、不被某家厂商的文件格式锁死。
这些年我试过市面上大部分 Markdown 编辑器，每个都有我喜欢的地方，也都有挡我事的地方。 我想要的是一个像桌面便签一样的工具：随手可呼、不要登录、不把我草稿同步到别人服务器。 所以我自己写了一个。
[ ] ↔ [x] 自动同步。茅泳涛。苏州大学附属第二医院关节外科医生，膝关节运动医学亚专科。 自学开发；mdEdit 是我自用多轮迭代打磨后才发布的独立小项目。
我还做了 KneeDaily，一款面向膝关节运动医学专科医生的每日文献推送 iOS App。 同样的单人开发原则：每篇中文摘要都由我本人亲自撰写和审校。
