How it works

Three steps to a conflict-free calendar.

Calendrz works silently in the background. Set it up once, and your availability stays accurate everywhere — automatically.

01 🔗

Connect your calendars

Link all your Google Calendars in one place — work, personal, side projects, anything. No limits on how many you connect.

02 👁

Calendrz reads your busy time

Whenever you have a busy event in any connected calendar, Calendrz detects it immediately — in real time.

03 🪞

Your availability is mirrored

Calendrz auto-blocks the same time slot across all your other calendars. Everyone sees you as busy. No double bookings, ever.

Why Calendrz

Built for people with more than one calendar.

Most people juggle two, three, even four calendars daily. Calendrz was built for exactly that.

🪞

True availability mirroring

Not a sync. Not a copy. Calendrz creates lightweight blocker events in your other calendars the moment a busy event appears — so every scheduling tool sees accurate availability.

Core feature
⚡

Auto-blocking in real time

The moment an event is marked busy, Calendrz acts. No delays, no manual triggers, no syncing windows. Your calendars are always up to date.

Real time
🎛

You control the rules

Choose which calendars mirror which. Block in one direction or all directions. Set working hours so personal time is never accidentally blocked during off-hours.

Flexible
🧹

Automatic cleanup

Cancel or move an event? Calendrz removes or updates the blockers everywhere, instantly. Your calendars never accumulate stale blocks.

Smart

New — AI & MCP

Now works with Claude and ChatGPT.

Connect Calendrz to your AI assistant via the Model Context Protocol. Ask Claude or ChatGPT about your availability, trigger a sync, or manage your connected accounts — all from natural conversation.

Booking tools finally see your real availability

Calendly and Google appointment pages only check one calendar. With Calendrz mirroring active, they see your true availability across all your accounts.
