qingjian

Project Overview

Qingjian is a cross-platform input method developed with Rust. Its goal is not just to "convert Pinyin to Chinese" but to make typing itself a lightweight, continuous, and nearly effortless way to learn a language. When you type, Qingjian displays a concise translation of the target language next to the candidate words.

Key Features

• Translation beside candidates: When your primary language is Chinese and you're learning English, English translations and parts of speech appear beside candidates
• One language at a time: Does not stuff multiple languages into candidate options, keeping the typing experience clean
• Local small model re-ranking: Type a full Pinyin sentence in one go, pause briefly, and a local small model re-ranks candidates
• Cross-platform design: macOS uses Input Method Kit, Windows uses TSF, Linux uses IBus / Fcitx

Target Audience

• Users who want to learn a foreign language while typing daily
• Chinese speakers, especially those learning English, Japanese, etc.
• macOS, Windows, Linux users

Quick Start

• Download the macOS or Windows version from qingjian.app/download
• Configure the input scheme according to the documentation after installation
• macOS version is available; Windows version is in beta (TSF text service + independent input engine process)

Core Advantages

• Input first, learning happens naturally — no interruptions, no pop quizzes, no forced memorization
• Runs locally, uploads no data
• Written in Rust for excellent performance
• Shows only one auxiliary language at a time for a clean interface

System Requirements

• OS: macOS, Windows, Linux
