Everest is an AI scheduling assistant and unified calendar for people who work across more than one calendar. It connects Google and Outlook accounts, shows them in a single view, and handles meeting scheduling over email on the user's behalf. The company describes it as an assistant that keeps calendars in sync and books meetings on the right one.
Its main idea is that most scheduling tools assume one job and one calendar. Everest assumes the opposite, which suits consultants, freelancers and agency owners with several clients. It is also positioned for anyone who wants work and personal commitments to stop colliding. Everest does not need access to the user's inbox.
The user adds Everest's assistant email address to the CC line of an email thread. Everest then proposes times from availability across every connected calendar, negotiates with the other person by email, and sends the invite once a time is agreed. It follows up if the contact goes quiet and reschedules if plans change.
Before booking, Everest re-checks availability and offers the nearest alternatives if a slot was taken. For meetings with several people, it proposes one set of times and books the earliest slot everyone confirms. Users can also message Everest in a chat, for example asking it to block lunch tomorrow for a meeting, and the assistant sends an invite on request.
The unified calendar shows personal, work and client calendars together, with Day, Week, Month, Year and Schedule list views. Calendars can be toggled on and off, and each new event is placed on a calendar the user chooses. Everest mirrors commitments as private Busy blocks on other calendars, with no titles or details, which helps prevent double-booking.
Everest also saves context from threads it joins. Names, email addresses and time zones go into the right workspace, so returning contacts are recognized and offered times in their own zone. The plans add working hours and scheduling preferences, time zone management and event reminders. Paid users can also schedule by text with Telegram.
