云候选是唯一一个不需要任何凭据、装完就把用户输入的拼写发到第三方（inputtools.google.com）的功能——AI 联想、翻译、语音都要用户自己填 token 才会发出请求。它出厂默认开启，而安装器此前只有 [Setup][Languages][Dirs][Files][Icons][Registry][Code] 七个段，没有 [Tasks]、没有同意页、没有首启引导。文档侧写得很清楚，但那要求用户先去读文档。 组织主页自己的立场是「隐私边界不该靠承诺保证」，而现在它靠的正是用户会去读文档。 在许可证页之后加一页联网功能选择：写明本地转换不联网、这一项是唯一装完就生效的联网功能、发送的是什么（当前拼写）和不发送的是什么（已上屏文本、词库、词频）、以及端点域名。复选框默认勾选，默认行为不变。 选择只写进本次安装刚生成的 config.toml，且只改 [general] 段里的这一个键。升级时整页跳过——那时 config.toml 已经属于用户，安装器不该替他重新决定。写入失败不影响安装成功。 轻量包不带出厂配置、不会生成 config.toml，因此整段用 #ifndef LightPackage 排除。
Metasequoia IME for Windows
A free and open-source Chinese and Japanese input method for Windows 10 and 11, built on TSF with no legacy IMM32 path.
This repository is the Windows product: the TSF text service DLL, the resident server, a self-written native GUI framework, the HTML surfaces and the installer. The conversion engine is shared with the macOS, iOS and Linux frontends and lives in MSIME-Engine.
This is a public beta. Expect rough edges and read the release notes before upgrading.
Install
Download the installer from Releases or the download page, run it, then switch with Win + Space.
Current builds are not code signed. SmartScreen will block them and uiAccess is unavailable, which means the candidate window cannot float above elevated applications. Verify the download with the SHA256 published on the download page.
You need the Microsoft Visual C++ 2015–2022 Redistributable (x64). The server and settings app are 64-bit; the x86 redistributable is a separate package and does not substitute for it. If you cannot switch to the IME, the server keeps exiting, or the settings window closes immediately, install that first.
What it does
- Chinese input: full pinyin, double pinyin (Xiaohe / Ziranma / Shoudao / Microsoft), Wubi 86
- Japanese input: romaji, with hiragana, katakana and dictionary candidates; also available as a temporary mode from Chinese
- Helpcode (形码) filtering on pinyin schemes: five tables, single- and double-code
- Optional cloud candidates, and AI suggestions via DeepSeek / OpenAI / SiliconFlow / Groq
- English-Chinese glosses in the vertical candidate window
- Mixed Chinese-English input, emoji and kaomoji, a dedicated English candidate mode
- Voice input with streaming recognition and optional cleanup
- Handwriting, on-screen keyboard, floating toolbar, clipboard history
- User dictionary management, candidate frequency tuning, skins with light and dark variants
Privacy
An input method sees every keystroke, so the boundaries are stated explicitly in PRIVACY.md: which features reach the network, what each one sends, what the defaults are, and how to turn each off.
Two things worth knowing up front. Cloud candidates are on by default — the composition spelling goes to Google's input-tools service, and it is the only network feature that works without you supplying a credential. API tokens are stored in plain text in config.toml, unlike macOS and Linux which use the Keychain and Secret Service.
There is no telemetry, analytics or crash reporting of any kind.
Building and contributing
CONTRIBUTING.md has the environment, the build order and what to run before opening a pull request. Contributions do not have to be code — dictionary entries, documentation, icons and compatibility testing all count, and the recruiting page lists them by area.
Note that most issues, documentation and code comments are in Chinese. English pull requests and issues are welcome.
