Mirror Your Availability. Automatically.·calendrz.com
Calendrz automatically mirrors availability across all of a user's connected calendars by creating blocker events whenever a busy event appears elsewhere. It supports connecting multiple Google Calendars with no limit, offers configurable mirroring rules and working hours, and integrates with AI assistants via an MCP server so tools like Claude and ChatGPT can read availability and trigger syncs.
