mi
mi is a macOS text editor for creating and editing plain text, code, and Japanese vertical-writing documents with extensive customization tools.
What is mi?
mi is a native macOS text editor designed for editing plain text, source code, and structured documents. It is aimed at Mac users who want a lightweight editor with more control than basic text apps, including support for large files and customizable editing behavior. The app is widely used for writing, programming, and text processing workflows, especially in Japanese-language environments where vertical writing and character-handling features are useful. mi also supports syntax-aware editing, search and replace, and user customization through tools and scripts that extend everyday editing tasks. For users who prefer a focused desktop editor instead of a full development environment, mi fits well into writing and coding workflows on Mac. It is published by Daisuke Kamiyama.

Safety overview
Status: Safe
mi is a legitimate desktop text editor for macOS. Access to files you open is normal for this type of app, and script or tool features are expected parts of an editor focused on customization. If you use custom scripts or external tools, treat them with the same care you would give any downloaded automation and only add items you trust.
Recommendation: Keep mi if you use it for writing, coding, or text processing on your Mac. If you no longer use the editor, you can remove it like other apps, though any personal settings or custom tools you created may need separate cleanup.
