Pixiv for Muzei 3 is a free personalization Android app developed by Antony Hu. It requires Muzei to be installed and is not a standalone app. The app features original quality artwork from a variety of sources, including daily, weekly, or monthly rankings, followed artists, bookmarked artworks, user's recommended feed, a specified artist ID, and a specified tag (date descending sort order).

Notably, Pixiv for Muzei 3 can filter against multiple criteria, including four levels of granular NSFW filtering, aspect ratio, view count, and manga. Users can delete specific artwork of their choice and the app supports OAuth2 authentication to prevent inbox flooding. Additionally, the app provides an option to automatically clear cache on a daily basis and the option to save artwork to external user storage.

Pixiv for Muzei 3 is open source and does not track or collect user details. However, the add to bookmark command only works on Android 9 and lower devices. The app is fully compatible with the new Muzei 3 API and the login is now working again.
