Karukan

What it is

A Japanese input method for Linux (as an fcitx5 add-on) and macOS that converts kana to kanji using small GPT-2 and Qwen3 based models run locally through llama.cpp. It offers live conversion as you type, context-aware suggestions, learning from chosen candidates, a SudachiDict-based system dictionary, user dictionaries in Mozc and Google IME formats, and emoji lookup. People who write Japanese on Linux or Mac desktops can use it in place of dictionary-only IMEs, with the model downloaded once and run offline afterward.
