Howie is an AI calendar secretary you loop in on email, iMessage or SMS. It reads the thread, checks your calendars, proposes times across time zones, handles replies, sends the invite and follows up when people go quiet.

Key features:

Scheduling over email and text, including messy group threads.
Booking links for any kind of meeting.
Focus blocks, holds, buffers, commutes and travel time added to the calendar.
Conflict and overloaded-day detection.
Remembered scheduling rules, such as limits on back-to-back meetings.
Reminders, to-dos, follow-up tracking and daily briefs.

Howie works from your inbox and messages, so there is no separate app to learn, and it connects your calendar to tools such as Granola, Linear, Notion and Todoist. It is aimed at busy professionals and teams who want executive-assistant style help with their calendar, and it can be started for free from the website.
