Diagramon 3.9.2 让「转换」多一道保险：转出来有损或直接报错时，可以交给你自己配置的模型修，并用数量对账判定修没修对。

下载

方式 文件 说明
安装版（推荐） Diagramon_3.9.2_x64-setup.exe（约 62.10 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-3.9.2-win-x64.zip（约 70.17 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

  • AI 增强转换（可选，默认关）：转换结果有损或有错时，入口才会出现（还要已配置模型、目标是文本格式）。
    一次初改 + 最多 3 轮校正，逐轮提示「第 N 次修正 / 剩余 M 次」；连续两轮同样错误会提前止损，不白烧额度。
    成功就另开标签页，失败保留本地结果并如实说明，不会给你一个空标签。
    首次使用会先提示「要外发什么」，可取消；调用计入 AI 用量。
  • 转换完成后做一次数量对账：自动数一遍节点与连线，少了就提示「少 N 个节点、M 条连线」。
    文本目标缺失算失败（可进入 AI 回灌）；drawio / Excalidraw 的缺失属于引擎表达力差异，只提示不阻塞。
    哪一侧数不出来就明说「对不了账」，不假装对得上。
  • 统一校验层：五种格式一个入口校验 —— Mermaid / DOT 给真实行列，D2 走随包 wasm 真编译，
    drawio / Excalidraw 做结构校验；引擎未就绪或文件过大时明确标「降级」，不把「没校验」当成「通过」。
  • 设置里新增开关：转换有损时允许用 AI 增强（默认关），附入口条件与额度说明。

修复

  • Mermaid 转 DOT / D2 不再被常见写法整份卡死：加长连接件（===> / ---> / -..->）、
    A --> B & C 多目标、subgraph id ["标题"] 与「连到 subgraph」的边现在都能转。
    这类文件以前会在报错行整份失败（真实语料里四个构造同时出现）。
  • 跨平面/跨容器的边不再多出空节点：subgraph 到 subgraph 的连线改成落在簇边界上。
  • 转换窗口里的报错可以复制：报错文字可选中，旁边还加了「复制」按钮；保真度说明与底栏文字同理。

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。

官网：https://www.diagramon.com

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_3.9.2_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 3.9.2 adds a safety net to conversion: when the result is lossy or outright fails, your own configured model can repair it — and a count check decides whether the repair actually worked.

Downloads

Type File Notes
Installer (recommended) Diagramon_3.9.2_x64-setup.exe (~62.10 MiB) Enables the built-in auto-update; if WebView2 is missing the installer downloads the runtime
Portable (no install) Diagramon-3.9.2-win-x64.zip (~70.17 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 works in the portable build, but updates are delivered as the installer
(it never patches the portable folder in place) — download the new ZIP to keep using it.

Highlights

  • AI-assisted conversion (optional, off by default). The entry appears only when it applies: the
    conversion is lossy or failed, a model is configured, and the target is a text format. One initial
    rewrite plus at most 3 correction rounds, with "attempt N / M left" progress; two identical failures
    in a row stop early so you do not burn quota. Success opens a new tab; failure keeps the local result
    and says so — never an empty tab. The first run shows exactly what will be sent (cancellable), and
    calls count toward your AI usage.
  • A count check after every conversion. Nodes and connections are counted and compared; if the
    result is short you get "N nodes / M connections missing". A shortfall on text targets counts as a
    failure (and can be fed back to the model); on drawio / Excalidraw it is an engine expressiveness gap,
    so it is only reported. When one side cannot be counted, it says so instead of pretending to match.
  • One validation layer for all five formats: Mermaid / DOT report real line and column, D2 actually
    compiles with the bundled wasm, drawio / Excalidraw get structural checks. When an engine is not ready
    or a file is very large, the result is explicitly marked degraded — "not validated" is never reported
    as "passed".
  • New setting: "Allow AI enhancement when conversion is lossy (off by default)", with the entry
    conditions and quota note.

Fixes

  • Mermaid → DOT / D2 no longer dies on common syntax: longer connectors (===>, --->, -..->),
    A --> B & C multi-target edges, subgraph id ["title"], and edges that connect subgraphs all
    convert now. Such files used to fail as a whole at the offending line.
  • No more phantom nodes for container-to-container edges: subgraph → subgraph links are clipped to
    the cluster border.
  • Errors in the conversion dialog can be copied: the text is selectable and there is a Copy button;
    the same applies to fidelity notes and the footer text.

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_3.9.2_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.
