Quick fixes
My AI says my Mac is not online
Wake your Mac and open Melvin on it, then ask again. Melvin turns a request down straight away when the Mac is asleep, rather than saving it to run later without you.
My AI is waiting for my iPhone
Open Melvin on your iPhone. iOS lets Melvin act only while it is open, so a request waits up to 10 minutes for you.
My AI cannot reach Melvin any more
Add Melvin to it again from the Connect page. Disconnecting all AI apps, or signing out everywhere, ends every connection at once.
I want to stop an AI app or a device
Your Devices page lists every device and what each is allowed to do. Remove a permission, disconnect a device, or disconnect every AI app at once.
