ChatGPT is the AI most people know, and it is very good at answering questions. It waits in an app for you to open it. Khio lives in your Messages, texts you first and keeps track of the things you are trying to stick to.
Checked 12 October 2026. A cross means ChatGPT 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 Khio wrote this page; if anything here is out of date, tell us through support and we will fix it.

Pick Khio if you want an AI that shows up in your day instead of waiting in an app. It texts you from a real number on iMessage, checks in morning and evening, joins your group chats, plays GamePigeon, logs your sets and counts calories from a photo of your plate. Free to start; Pro is $14.50 a month.
No. OpenAI's 1-800-ChatGPT line is for voice calls, and its help pages list no iMessage or SMS texting. Khio texts from a real phone number over iMessage, so it sits in Messages next to your friends.
ChatGPT's Pulse daily updates are on the Pro plan, and its scheduled tasks arrive as a push notification or an email. Khio sends morning and evening check-ins, follow-ups and a weekly recap as ordinary iMessage texts.
No. OpenAI retired ChatGPT group chats: since 9 July 2026 you cannot create or join one. Khio joins any iMessage group to run a poll, pick a time and follow up.
Khio builds your routine, logs every set you text it, remembers what you lifted last time and flags a new personal record the moment you log it. ChatGPT gives workout advice, and in the US can read Apple Health, but it does not keep a workout log for you.
