calenai

calen is an AI calendar assistant that automates calendar management by scheduling meetings, rescheduling events, finding free time, and managing calendars via plain-language chat. It operates across multiple channels — web app, Telegram, and email (including CC-ing calen on threads) — and integrates directly with Google Calendar to sync events in real time. The product positions itself as an "Executive Assistant AI" that handles invites, conflict resolution, and event creation so users can schedule and modify meetings without manual form-filling or email back-and-forth.

AI scheduling agent with humanlike voice for simplified intake and increased bookings.
