一个编辑器该有的，都在里面 Everything an editor should have

用 Swift 和 AppKit 写成，没有 Electron，也不需要你先去装别的工具。 Written in Swift and AppKit. No Electron, and nothing to install alongside it.

实时预览Live preview

标题、链接、代码、公式在编辑区里直接成形，不用来回切换。要并排对照时切到分栏；KaTeX 公式、代码高亮和 Mermaid 图表随应用离线打包，断网也能渲染。 Headings, links, code and formulas take shape right in the editor. Split the window when you want them side by side — KaTeX, syntax highlighting and Mermaid ship inside the app and render offline.

真的轻Genuinely light

整个应用 18 MB，磁盘映像 11 MB，一个通用二进制同时支持 Apple 芯片和 Intel。不捆绑浏览器内核，也不捆绑 Python 运行时。 18 MB installed, an 11 MB disk image, one universal binary for both Apple silicon and Intel. No bundled browser engine, no bundled Python runtime.

20 套配色20 color themes

10 套浅色、10 套深色，浅色模式和深色模式各挑一套，应用外观跟着走。正文、标题、代码三种字体，字号、行高、行宽、段落间距逐项可调。 Ten light, ten dark. Pick one for light mode and one for dark, and the app follows. Separate fonts for body, headings and code, with sliders for size, line height, line width and paragraph spacing.

文件夹就是工作区A folder is the workspace

打开任意文件夹就能开始写。侧栏是真实的目录树，[[Wiki 链接]]、大纲、全文搜索和命令面板都在手边，没有专有格式，没有数据库。 Open any folder and start writing. The sidebar is the real directory tree, with [[wiki links]], an outline, full-text search and a command palette. No proprietary format, no database.

版本历史与备份History and backup

本地保留历史版本，写错了随时翻回去。备份指向你自己的 S3 兼容存储，访问凭据存在系统钥匙串里，不经过任何中间服务。 Earlier versions are kept locally, so you can always go back. Backup points at your own S3-compatible storage, with credentials in the system keychain and nothing in between.

格式转换内置Conversion, built in

Word、PPT、Excel、EPUB、PDF、网页、图片、录音都能变成 Markdown；写完再导出成 HTML、PDF、Word、EPUB、LaTeX。不用装 Pandoc，也不用装 Python。 Word, PowerPoint, Excel, EPUB, PDF, web pages, images and recordings all become Markdown — and your writing exports to HTML, PDF, Word, EPUB or LaTeX. No Pandoc, no Python.

挑一套看着舒服的 Pick one that’s easy on the eyes

每套主题都覆盖编辑区、标题、强调色和侧栏。点一下试试——下面是实际的配色取值。 Each theme covers the editor, headings, accents and sidebar. Give one a tap — these are the app’s actual values.

别的格式进得来，出得去 Other formats come in, and go out

转换全部在应用里完成，不需要安装外部工具，也不会把文件传到别处。 All conversion happens inside the app — nothing to install, and nothing leaves your Mac.

变体也认：.doc、.dotx、.pptm、.xlsm、.htm、.tsv 这些都会走同一条转换路径。图片里的文字用系统的文字识别提取（中英日韩），录音用本机语音识别转成文稿——音频不上传。 Variants are handled too — .doc, .dotx, .pptm, .xlsm, .htm and .tsv all take the same path. Text inside images is read with the system’s on-device recognition (Chinese, English, Japanese, Korean); recordings are transcribed locally — audio never leaves the Mac.

写作时的一些小事 The small things, while you write

专注模式与打字机滚动Focus mode and typewriter scrolling 当前段落之外的文字淡下去，光标一直停在屏幕中间。 Everything but the current paragraph fades back, and the caret stays mid-screen.
格式工具栏与命令面板Formatting bar and command palette 常用格式一键可得，其余功能按名字搜出来执行。 Common formatting is one click away; everything else is a search away by name.
图片随文入库Images land beside the text 粘贴或拖进来的图片会存进文档所在文件夹，链接写成相对路径。 Pasted or dropped images are saved next to the document and linked by relative path.
中英文界面English and Chinese 界面语言可以在设置里切换，重启后生效。 Switch the interface language in Settings; it applies after a restart.
应用内更新Updates in place 更新信息带 Ed25519 签名，校验通过才会安装。 Update manifests are signed with Ed25519 and verified before anything is installed.
四个应用图标Four app icons 蓝、红、绿、石墨，随时在设置里换一个。 Blue, red, green and graphite — swap any time in Settings.
