AI assistants for executives: tools, playbooks and safety

Published by 3Gen Internet Corporation, maker of OpenAssistant, Skej and AGNT. Comparisons use public documentation, without hands-on testing.

These 20 articles are for executives, founders and the executive assistants who support them. Some compare tools for a specific role, such as CEO, founder, investor, nonprofit director, Outlook user or frequent traveler. Others are step-by-step playbooks for handing over your inbox, calendar and meeting prep without losing control, and for writing the instructions, checking the results and knowing what to keep for yourself. In the role-based comparisons, OpenAssistant is our first pick wherever its public pages support it, and each article says plainly where a competitor does better.
