Everest review
A web-based calendar that combines multi-account views with email-based meeting negotiation.
Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
Everest is a web-based calendar and scheduling assistant for consultants, freelancers, agency owners, and teams coordinating several personal, work, or client calendars. It connects Google Calendar and Microsoft Outlook accounts in one view, checks availability across them, and supports read/write event management. Its central differentiator is an email-thread assistant that proposes times, negotiates availability, books meetings, reschedules or cancels them, and follows up. Chat-based scheduling, Telegram scheduling, working hours, time-zone management, and private busy-block mirroring add flexibility for people managing overlapping calendars.
The free Everest Calendar plan includes a unified calendar, Google and Outlook integrations, working hours and scheduling preferences, time-zone management, and event reminders. The Everest Assistant plan costs $25 per month with monthly billing or $20 per month with annual billing. It adds unlimited calendar integrations, unlimited meetings booked, Telegram scheduling, and priority support. The published Enterprise plan adds scheduling on behalf of several people, a custom assistant domain, shared scheduling policies, SSO, DPA and data-retention controls, plus dedicated support. This structure suits individuals who need consolidated calendars on the free plan and teams that need automated scheduling or administrative controls on paid tiers.
Everest fits workflows centered on Google Calendar, Microsoft Outlook, email, and Telegram. Its two-way calendar sync and availability checking are useful when commitments span multiple accounts, while email negotiation reduces the need to coordinate times manually. The trade-off is scope: Everest is web-only, and its strongest automation is tied to the Assistant tier rather than the free calendar. Teams needing scheduling on behalf of several people, custom domains, shared policies, or enterprise controls should consider Enterprise. People seeking a straightforward multi-account calendar can start with Everest Calendar, while email-heavy schedulers are the clearest fit for Assistant.
