About MugJai

MugJai is a bilingual (zh-Hant-HK + en) app that turns trusted editorial guides into an in-app AI assistant for rent, finance, wellbeing, and living on your own.

Ask grounded questions with citations, pick General assistant or Support companion, manage persona-scoped master notes, save checklists, and leave feedback. CMS is the only knowledge source — no open-web search; no ads.

We do not provide personalised tax, legal, or financial advice. Double-check important decisions with the relevant authority.
