Kai

Kai positions himself as an “AI administrative assistant,” targeting a very specific group of people: freelancers, owners of one-person companies, and founders of early-stage startups—individuals who simply cannot afford a secretary but are constantly overwhelmed by emails and meetings.

It integrates with email, calendars, and to-do lists simultaneously. The inbox is first sorted by this system, with important emails generating draft replies; meeting schedules are arranged according to your actual available time; and after meetings, the system automatically organizes the minutes. Even more useful is its ability to keep track of commitments you have made in emails or during meetings, reminding you before they are due to prevent any promises from being forgotten or not fulfilled.

The official website states that it is possible to try the service without linking a credit card first. For those who handle hundreds of emails every day, this option is definitely worth trying. However, it requires relatively high levels of access to email accounts and calendars; users who are concerned about data privacy should read the terms of service carefully before using it.
