Cal Autobot vs DayOtter

CC it on an email thread and it can read the exchange, propose times, follow up, and send reminders. It monitors multiple calendars for conflicts and lets users choose a source of truth. A branded public booking page syncs with email bookings, while event details from emails, pictures, and itineraries can be turned into Google Calendar events. Its free Gmail Chrome extension tracks email opens and adds availability or a booking link with one click.
