What is Zitli?

Zitli is an online appointment booking tool for self-employed professionals and small practices in Switzerland. You share a booking link, your clients see only the times when you are actually free, and they book themselves. The booking goes straight into your calendar.

What makes Zitli different

• Cantonal public holidays built in: the public holidays of all 26 cantons are included. You choose your canton, and no one can book on those days.
• Four languages: the app and your booking page are available in German, French, Italian and English. You work in your language, your clients book in theirs.
• Prices in CHF including VAT: payment by TWINT or card, invoices with VAT shown separately.
• Swiss company, hosted in the EU: Zitli is operated by Otternative Marketing GmbH in Basel. The data is stored in data centres in the EU (designed around the Swiss FADP and the GDPR).
• Open core: Zitli is based on the open-source scheduling software cal.diy (from the Cal.com family).

What you can do with Zitli

• Create event types (e.g. initial consultation 30 min, follow-up 60 min), each with its own link
• Connect Google Calendar, Outlook / Microsoft 365, Apple Calendar or CalDAV so you are never double-booked
• Automatically create a Google Meet, Zoom or Microsoft Teams link for every booking
• Have confirmations and reminders sent by email
• Accept payments at booking (Pro)
• Embed the booking page on your own website
• Connect Zitli to AI assistants such as Claude or ChatGPT
