* fix(ui): SVG 按整像素栅格化、滚动改为跟手的指数滑动，并可预热 D3D 设备 - GetSvgBitmap 按四舍五入的像素尺寸建位图，避免 D2D 向上取整后被挤压采样 - ScrollViewer 平滑滚动改为按帧时间逼近目标：连续滚轮不再每格从零速重起， 内容按整设备像素排布，滑动中文字不再抖动 - 新增 DeviceResources::PrewarmComposition，在后台线程提前创建 D3D11 设备， 首帧复用，省去约 200ms 的驱动初始化 * fix(server): 修复 Direct2D 设置窗口的图标、检查更新与热力图交互，加快冷启动 - 侧栏等 SVG 图标对齐设备像素绘制，不再发糊 - 关于页「检查更新」：页面持有状态，点击不再无反应；按钮加悬停描边与按下位移； 后台任务结果改为投递消息回窗口，窗口被遮挡时不再因 WM_TIMER 被压制而卡在「正在检查…」 - 弹窗按显式宽度测量内容，换行文字不再与下一行重叠 - 以 --about 打开时侧栏指示条落在「关于」 - 日历热力图可横向滚动（拖动滑块、点击轨道、Shift+滚轮），滚动条与竖向一致： 8px、无箭头、2px 圆角；悬停格子 500ms 后显示日期与字数 - 滚轮每格 60px；暗色主题首帧前不再闪白（按主题色擦底并在首帧前隐藏窗口） - 启动时预热 D3D 设备，首帧从约 300ms 降到约 140ms * fix(ui-html): 热力图滚动条与页面竖向滚动条一致，检查更新按钮加悬停与按下反馈 与 Direct2D 设置窗口的同步改动保持一致。
Metasequoia IME for Windows
中文 README · Website · Docs · Privacy · Code signing policy
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 whole Windows product: the TSF text service DLL, the resident server, the conversion engine, a self-written native GUI framework, the HTML surfaces and the installer. The engine was imported from MSIME-Engine and specialized for Windows; it now lives in engine/ as a first-party component, so a plain clone builds the product. See engine/UPSTREAM.md.
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 / Sogou / Ziguang / Zhineng ABC / Guobiao / Pinyin Jiajia), 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: six 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
- Local input statistics (off by default): character counts and active time stay on this machine; view and clean them under Settings → Statistics
- 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.
