Calendrz is a tool designed to automatically mirror a user's availability across multiple connected calendars, addressing the issue of double bookings for individuals who manage several calendars simultaneously. The platform is intended for people who juggle work, personal, and side project calendars, ensuring that when a user is marked as busy in one calendar, all other connected calendars reflect that status in real time.
The core functionality of Calendrz involves linking multiple Google Calendars without restrictions on the number of accounts. Once connected, the service detects busy events as soon as they are created and immediately creates lightweight blocker events in the other calendars. This ensures that scheduling tools and others viewing the user's calendars always see accurate, up-to-date availability. Calendrz offers flexible control, allowing users to choose which calendars mirror each other, set blocking directions, and define working hours to prevent personal time from being blocked during off-hours. If an event is canceled or moved, the tool automatically updates or removes the corresponding blocker events, preventing the accumulation of outdated blocks.
Calendrz also integrates with AI assistants such as Claude and ChatGPT through the Model Context Protocol (MCP), enabling users to query their combined availability, trigger calendar syncing, or manage accounts via natural language conversation. The platform allows users to trigger availability mirroring by voice and provides AI assistants with a comprehensive view across all connected accounts. 1, ensuring that Google and Microsoft credentials are not exposed to the AI assistant.
The service is web-based and can be set up in under two minutes. It offers a free account option, allowing users to connect their calendars, configure rules, and begin automatic mirroring without cost. Calendrz is positioned as a solution for anyone needing to maintain accurate, conflict-free scheduling across multiple calendars.
