azooKey

azooKey for macOS is an open‑source Japanese input method that incorporates the neural kana‑kanji conversion engine Zenzai. It runs on macOS 15 and later, with basic compatibility reported for macOS 14 and 26, and is distributed as a .pkg installer or via Homebrew. After installation the user adds azooKey as a Japanese input source in System Settings and can select it from the menu bar.

The system offers high‑accuracy conversion, a profile prompt feature, learning from typing history, a user dictionary, and integration with the personal‑optimization tool Tuner. It also supports live conversion, native AZIK input, and an LLM‑based “nice conversion” mode. Developers can build the project from source using Xcode 26.1+, Git LFS, and SwiftLint, and the repository includes scripts for packaging and upgrading.

azooKey is aimed at macOS users who need a customizable Japanese typing experience, and it invites contributions through its Discord community and GitHub. The project is maintained under a stable maturity level, though the current release is marked as alpha with no operational guarantees.
