calendar to rule them all

Your schedule is scattered.
None of it's your fault.

Events arrive through a dozen different channels. Most never make it to your calendar. The ones that do are manually entered, incomplete, or duplicated.

📬

Inbox chaos

Eventbrite tickets, Zoom confirmations, Calendly bookings, travel receipts — all buried in threads. Finding the join link at 9:58 AM is a ritual nobody wants.

🗓️

Incomplete calendar

You manually add some events but miss others. The calendar you carry is never the full picture. You're operating from partial, unreliable information every week.

🔄

Duplicate entries

Three confirmation emails for the same flight. A calendar invite and a Calendly link for the same call. Spotting duplicates takes time you don't have.

Five steps from inbox
to organized schedule.

One source of truth
for your week.

Not another calendar app. Not another inbox tool. The AI layer between your confirmations and your schedule.

🌐

Universal ingestion

Direct integrations where APIs exist, intelligent email parsing everywhere else. Nothing slips through.

🧠

AI normalization

Raw, messy confirmation emails become clean, structured calendar events. Titles cleaned. Timezones resolved. Join links surfaced.

🛡️

Duplicate prevention

Three confirmation emails shouldn't mean three calendar entries. Calzine detects and eliminates duplicates automatically.

One source of truth

Your Google Calendar becomes the single place where everything lives — every meeting, booking, ticket, and appointment.

Built for anyone whose
inbox runs their week.

If your schedule is driven by confirmation emails, registrations, and bookings, Calzine was designed for you.
