Fo, from Wajo, is an AI assistant that phones, emails and texts people for you: the plumber, the dentist, the airline. Kiwi does your errands too, and its speciality is going first. It reads your calendar and email and texts you when something needs you, before you'd have noticed.

Going first
Fo is at its best when you hand it a job that means talking to people, and it gets on with it. Kiwi's speciality is starting before you ask: a reply you owe, a renewal coming up, a meeting in an hour, a flight that moved. It texts you once, at the right time, and keeps anything that can wait for one morning text. Say yes and it does the job on any app or website.
WhatsApp and the rest of the world
Fo's help page says WhatsApp isn't available, and its numbers are US numbers. Kiwi works on WhatsApp as well as on iPhone, so it suits people who live in WhatsApp, wherever they are. More in Kiwi on WhatsApp.
Your data
Fo's privacy notice says personal information may be used to develop, train and fine-tune its models. Kiwi doesn't use your conversations or connected accounts to train general-purpose AI models. More in Is Kiwi safe?
