青简输入法 Qingjian

Qingjian is a Rust-based pinyin input method for macOS and Windows that displays English or Japanese translations next to candidate characters as you type. It processes pinyin, word selection, and language models locally without uploading data. The input method supports full-sentence conversion with on-device model reranking, fuzzy matching, spell correction, and dual-pinyin input. Language learning happens passively—new words appear in orange and fade as you encounter them repeatedly. The tool learns your preferences, word frequency, and typing patterns locally to improve suggestions over time.
