中文

Diagramon 3.10.4 把「读懂一张图」做成了 AI 面板里的第一个只读页签，并让视图跟着渲染区域的尺寸自己适应。

下载

方式 文件 说明
安装版（推荐） Diagramon_3.10.4_x64-setup.exe（约 62.13 MiB） 装完可用内置自动更新；缺 WebView2 时安装器会自动下载运行时
便携版（免安装） Diagramon-3.10.4-win-x64.zip（约 70.19 MB） 解压到任意位置，双击 diagramon.exe 即用；卸载 = 删文件夹

便携版说明：包里是 diagramon.exe + WebView2Loader.dll + ui\ + assets\，必须放在一起
（ui\ 与 assets\ 是从磁盘读的，不在 exe 里）。它不依赖额外要装的东西：不需要 Node.js、
不需要 Chrome、不需要 VC++ 运行库（exe 已静态链接 CRT），只需要 Windows 10/11 自带的 WebView2 运行时。
便携版的「检查更新」照常能发现新版，但更新走的是安装包（不会就地替换便携目录）——
要继续用便携形态，就手动下载新的 ZIP 覆盖。

本次亮点

  • 新增「解图」页签（AI 面板第 4 个）：只读解读当前图 —— 它描述什么、主链路怎么走、
    模块边界在哪、哪些异常分支或设计风险值得注意。不产出代码、没有「应用」按钮、不动文档。
    回复落在这个页签自己的会话里，按文档持久化，「历史会话」里照样找得回。
  • 四条直接入口，都指向同一件事：
    • AI 菜单 →「解图：只读解读当前图」
    • 快捷键 Ctrl+Shift+E
    • 命令面板（Ctrl+Shift+P）→「解图…」
    • 预览顶栏的「解图」按钮，或文档标签右键 →「解图（只读解读）」
      面板空态另给一个主按钮与三个角度词（讲什么 / 主链路 / 风险），点一下直接发。
  • Ctrl+Shift+E 在面板收起时也能用：按下就把面板打开、切到「解图」并开始解读。
  • 渲染区域尺寸变化时自动适应视图（新增设置，默认开，见「设置 → 编辑器」）：
    拖分隔条、开合侧栏 / AI 面板 / 底部面板、切视图模式、缩放窗口之后，图会按新尺寸重新适应并居中，
    等同点一次「适应视图」。不想要这个联动可以关掉，关掉后视口只在打开/切换文档与显式适应时变。
  • AI 页签改名：原来的「对话生成」改为「生图」，与旁边「识图」「改图」「解图」四个动作对齐。

修复

  • 「解释这张图在讲什么」不再变成画图：「生图」页签里的那颗建议词以前只是把文字填进输入框，
    发出去的是"画一张图"的意图；现在它直接落到「解图」页签按只读意图发。
  • 恢复出来的历史会话重试时不会走错意图：从磁盘还原的轮次以前丢了所属页签，
    在「改图」里点重试会被当成"从头生成"；现在按原页签还原。
  • 改尺寸后图不再只露一角：以前把一个面板拖窄或把窗口放大后，图仍按旧尺寸的缩放待着；
    现在是按新视口重新适配并居中（可关，见上）。

关于 Diagramon

Diagramon 是一款本地优先的多格式图表编辑器：Mermaid / Graphviz DOT / drawio / Excalidraw
都可编辑并实时预览，AI 可辅助生成、评审与识图。渲染与校验不联网也能用 ——
只有你主动使用 AI 时，相关代码或图片才会发往你选择的上游。

系统要求

  • Windows 10 / 11 64 位
  • WebView2 运行时（Windows 10/11 通常已预装；缺失时安装器会现场下载）
  • 不需要 Node.js、Chrome 或 VC++ 运行库 —— 画布运行时与前端资源都随包分发

安装与更新

下载 Diagramon_3.10.4_x64-setup.exe 直接安装。已装旧版的用户可在
帮助 → 检查更新 里收到本版本（更新包即本安装包，签名见 latest.json）。

本安装包尚未做 Authenticode 代码签名，Windows SmartScreen 可能给出提示。

English

Diagramon 3.10.4 turns "read this diagram" into the AI panel's first read-only tab, and lets the view refit itself when the render area changes size.

Downloads

Type File Notes
Installer (recommended) Diagramon_3.10.4_x64-setup.exe (~62.13 MiB) Enables the built-in auto-update; if WebView2 is missing the installer downloads the runtime
Portable (no install) Diagramon-3.10.4-win-x64.zip (~70.19 MB) Unzip anywhere and run diagramon.exe; uninstall = delete the folder

About the portable build: it ships diagramon.exe + WebView2Loader.dll + ui\ + assets\, and those
must stay together (the ui\ and assets\ trees are read from disk, not embedded in the exe).
It needs nothing extra installed: no Node.js, no Chrome, no VC++ redistributable (the CRT is
statically linked) — only the system WebView2 runtime that comes with Windows 10/11.
"Check for updates" still finds new versions, but updating downloads the installer
(it does not replace the portable folder in place) — to stay portable, grab the new ZIP manually.

Highlights

  • New "Explain" tab (the 4th tab in the AI panel): a read-only reading of the current diagram —
    what it describes, how the main path flows, where the module boundaries are, which error branches or
    design risks deserve attention. No code output, no Apply button, no edits to the document.
    Replies live in this tab's own conversation, persisted per document and listed in History.
  • Four direct entry points, all landing on the same action:
    • AI menu → "Explain: read-only read of the current diagram"
    • shortcut Ctrl+Shift+E
    • command palette (Ctrl+Shift+P) → "Explain…"
    • the "Explain" button in the preview header, or right-click a document tab → "Explain (read-only)"
      The empty state adds a primary button and three angle chips (what it says / main path / risks) that send
      directly.
  • Ctrl+Shift+E also works with the panel collapsed: it opens the panel, switches to Explain and
    starts the reading.
  • Auto-fit when the render area resizes (new setting, on by default, under Settings → Editor):
    after dragging the splitter, toggling the sidebar / AI panel / bottom panel, switching view modes or
    resizing the window, the diagram refits and re-centres exactly as pressing "Fit view" would. Turn it off
    and the viewport only changes on open/switch and on an explicit fit.
  • AI tab renamed: "Chat generation" is now "Generate", matching the four actions
    Generate / Vision / Review / Explain.

Fixes

  • "Explain what this diagram is about" no longer draws a diagram: the suggestion chip under the
    Generate tab used to only fill the input box, and the request went out with the "draw a diagram" intent;
    it now jumps to the Explain tab and sends with the read-only intent.
  • Restored conversations retry with the right intent: turns loaded from disk used to lose their tab,
    so retrying a Review turn was sent as "generate from scratch"; they are restored with their tab now.
  • The diagram no longer ends up half out of view after a resize: narrowing a panel or enlarging the
    window used to leave the old zoom in place; it now refits and re-centres on the new viewport (can be
    turned off, see above).

About Diagramon

Diagramon is a local-first multi-format diagram editor: Mermaid, Graphviz DOT, drawio and Excalidraw
can all be edited with live preview, with AI assistance for generation, review and image recognition.
Rendering and validation work with no network at all — code or images reach a model only when you
actively use AI, and then only the endpoint you chose.

Requirements

  • Windows 10 / 11 64-bit
  • WebView2 runtime (normally pre-installed on Windows 10/11; the installer downloads it if missing)
  • No Node.js, Chrome or VC++ redistributable needed — the canvas runtimes and front-end assets all
    ship inside the installer

Install and update

Download Diagramon_3.10.4_x64-setup.exe and run it. Users on an older version
will be offered this release via Help → Check for updates (the update package is this same
installer; its signature is in latest.json).

This installer is not yet Authenticode-signed, so Windows SmartScreen may show a warning.
