Muse is Meta's personal AI agent: it does tasks for you in its app or in WhatsApp. Khio is the friend in your iPhone's Messages who texts you first, joins your group chats and keeps you on track with the gym, food, habits and school.
Checked 12 October 2026. A cross means Muse does not offer it, or its own site, help pages and App Store listing do not say it does. Khio wrote this page; if anything here is out of date, tell us through support and we will fix it.

No. Meta says you chat with Muse in the Muse app on mobile or Mac, or in WhatsApp. Khio texts from a real phone number over iMessage and joins iMessage group chats.
Both coach you. Muse builds workout plans and tracks calories and sleep. Khio builds your routine too, logs every set you text it, flags personal records the moment you hit them and counts calories from a photo of your plate.
Muse's App Store listing is rated 18+. Khio is built for students too: it turns your own notes into flashcards and a practice test, and texts you before exams.
