CloudInputMethodEditor

Project Overview

Cloud IME is a fork that branched off from the Qingjian input method, with the emphasis on everyday experience: fuzzy pinyin, error correction, custom phrases and user dictionaries. The author found Qingjian powerful but bloated, since not everyone needs candidate translation and cloud completion, and rebuilt the input method almost from scratch.

It is written in Rust and open source under GPL-3.0, targeting 64-bit Windows 10/11. Full pinyin (with abbreviated pinyin) is supported today, with double pinyin, Wubi, Cangjie and more to open up gradually.

License	GPL-3.0

A purely local input method, WYSIWYG and free of distractions, bringing typing back to basics.

Key Features

• Full pinyin input: full and abbreviated pinyin today, with double pinyin, Wubi, Cangjie and other niche methods opening up over time
• Fuzzy pinyin and correction: tolerance for common confusions such as retroflexes and nasal finals, cutting backspaces
• Custom phrases: frequent sentences and special symbols map to short abbreviations for one-shot entry
• User dictionaries: user dictionary management plus the official dictionary, usable out of the box before any third-party import
• Fully local: every action happens on the machine, no network, no privacy harvesting, fully open source
• Translation tip: candidate translation from Qingjian becomes a passive tip, reducing visual noise for pure typing

Target Audience

• Privacy-sensitive users who dislike cloud completion and online IMEs
• Speakers with accents who rely on fuzzy pinyin
• Writers boosting typing speed with custom phrases
• Windows users wanting a light, pure full-pinyin experience

Quick Start

1. Download the Windows installer from Releases (with a SHA256 checksum file)
2. After installing, enable Cloud IME in the system input method list
3. Switch to Cloud IME and start typing, jianpin works by default
4. Configure fuzzy pinyin schemes and custom phrases in settings
5. Import third-party dictionary files if you need a larger vocabulary

Core Advantages

• Privacy first: zero-network design, keystrokes never leave the machine
• Focused experience: heavy features like cloud completion are cut so fuzzy pinyin, correction and dictionaries get done well
• Auditable: GPL-3.0 with a Rust implementation, you can read the code yourself
• Light and pure: clean interface and candidate behavior with distractions removed

System Requirements

Item	Requirement
OS	Windows 10 / 11
Architecture	64-bit
Input method	Full pinyin (with jianpin), more to come

Notes

• Input methods still expanding: only full and abbreviated pinyin today, double pinyin, Wubi and Cangjie arrive gradually
• A Qingjian fork: some behavior carries over from Qingjian, migrants will feel at home
• Third-party dictionaries DIY: no third-party dictionaries ship with the installer, find and import your own
