OneCal
Sync your calendars, avoid scheduling conflicts
OneCal is a calendar management tool that synchronizes multiple calendars in real time, helping users avoid double bookings and manage availability across personal and work schedules. It supports Google Calendar, Outlook, iCloud, and CalDAV servers, with configurable sync directions and privacy controls that let users choose which event details are replicated. Scheduling links can be shared for individual or team bookings, and a unified calendar view brings multiple calendars together for creating, updating, and RSVPing to events.
The platform includes an AI assistant for managing calendar changes, syncs, and scheduling links, plus an MCP server that connects AI tools such as Claude and ChatGPT to calendar data. Video conferencing integrations include Zoom, Microsoft Teams, and Google Meet, with meeting links attached to bookings. Zapier connects OneCal to thousands of additional apps. Mobile apps for iOS and Android mirror the web experience. OneCal is available on a free plan without requiring a credit card, and it offers individual and team scheduling links.
