Kai is an AI executive assistant operated by Morgen AG in Zürich, Switzerland. It monitors email, meetings, and direct messages, then follows up on commitments. Kai connects with Gmail, Google Calendar, Outlook email, and Microsoft Outlook calendar to triage incoming mail, draft replies, schedule events, reserve focus time, and identify conflicts. It captures Zoom, Google Meet, Microsoft Teams, Webex, and Slack huddles without a bot joining the call. Meeting and email action items become tracked tasks that retain their original context, although external task-manager syncing is not supported. Users review drafts, tasks, and calendar changes, and messages are not sent without explicit action or approval. Kai works on Android, iOS, macOS, and the web, and offers MCP connections for Claude, ChatGPT, and Cursor; Gemini is listed as a connector in its privacy policy. A usage-based free trial has no time limit. Base costs 20.00 USD per user monthly, while Pro costs 50.00 USD per user monthly.
