Why Zeeg

Appointments Without a Second Booking Tool

While smao needs another booking tool to actually create the appointment in the calendar, Zeeg books directly through its own system — straight from the call to your calendar: Google Calendar, Apple, Outlook, Proton, and more.

Outbound Calling, Not Just Inbound

Zeeg's AI phone agent also calls out: upload your contacts and launch your follow-up or engagement campaigns. With a few clicks, you automate your outbound phone system.

Simply a better pricing

Smao's plans lock you into a 12-month commitment (their only contract-free option costs €0.35/minute). But with Zeeg, you can get billed monthly, at a lower cost per minute, with no long-term contract required.

Distribute Calls with Round-Robin and Lead Routing

With Zeeg, not only can you route to specific teams or team members depending on your caller's answers, you can also distribute appointments fairly among your team with round-robin scheduling.

GDPR-Compliant, Hosted in Germany

Your call data and records never leave the EU. Zeeg is fully GDPR-compliant, with all servers hosted in Germany, so every conversation, booking, and contact record stays under German and European data protection law.
Features

The Most Advanced AI Voice Agent

Here's some of the main features that you can get today.

Phone Booking

Around the clock, your AI phone assistant picks up and places calls, asks the right questions, qualifies the caller, and locks in the appointment before the conversation ends.

Outbound Campaigns

Run bulk outbound calling campaigns to re-engage cold leads, win back past customers, or resolve open issues across your whole contact list at once.

Smart Routing

Set your own qualifying questions, sort leads by what matters to you, and send each caller straight to the right person or team, whether they dialed in or booked online.

Online Scheduling

Give prospects a booking page that's always open. Sync your calendar, define your available hours, share the link, and let bookings come in on their own.

Round-Robin

New appointments get spread evenly across your team on their own, following whatever rules you set, so no one person ends up overbooked.

Calendar Integration

Hook up Google, Outlook, Office 365, Exchange, Apple Calendar, Proton, or others, and let every booking sync across all of them without any manual work.

Video Integration

Pick the video tool that fits your workflow when you set up your booking page: Google Meet, Microsoft Teams, Zoom, or Webex all work.

Workflows

Set reminders, follow-ups, and confirmations to go out automatically by email and SMS, cutting down on the number of appointments people forget.

Team & Workspace Coordination

Keep every team calendar aligned, manage who has access to what, and move between different teams or workspaces whenever you need to.

smao vs Zeeg

Quick take

Smao is a solidly built, GDPR-compliant AI phone assistant hosted entirely in Germany, with a strong data-sovereignty story (no OpenAI, no US AI subprocessors) and broad integration support across CRM, helpdesk, and ticketing tools. But smao relies on a separate booking tool like Cal.com to actually create the appointment, and its better per-minute rates require a 12-month commitment.

Zeeg, on the other hand, has its AI phone assistant and appointment booking engine in the same system. Inbound and outbound calls, qualification and booking, they all happen within Zeeg. Plus, with Zeeg you get a more competitive pricing.

Zeeg verdict:
The right choice for teams that want native booking without a second tool, more competitive pricing, fair call distribution and routing, and the flexibility to leave anytime.

smao verdict: A fair choice for teams already using Cal.com, and comfortable committing to 12 months for better per-minute rates.

Frequently asked questions

What's the difference between Zeeg and smao?
smao is an AI phone assistant that hands off actual appointment booking to a connected tool like Cal.com. Zeeg is an AI phone assistant with native appointment booking — it answers the call, calls out proactively, qualifies the lead, and books the appointment directly in your calendar.
Does smao make outbound calls?
Yes. smao supports outbound calling for use cases like appointment confirmations, satisfaction surveys, and lead re-qualification. Zeeg also supports outbound calling, built into the same AI agent as inbound.
Does smao book appointments on its own?
Not entirely. smao takes the call and checks calendar availability in real time, but the appointment itself is created and synced through a connected booking tool such as Cal.com. Zeeg books directly into your calendar with no second tool in the loop.
Is smao or Zeeg cheaper?
It depends on volume, but Zeeg's per-minute rates are lower at every comparable tier — around €0.128/min at ~1,250 minutes versus smao's €0.20/min, and around €0.11–0.12/min at ~3,000 minutes versus smao's €0.15/min. smao's better rates also require committing to a minimum 12-month term; Zeeg doesn't require any long-term contract.
Does smao lock you into a contract?
Yes — smao's Advanced and Scale plans both require a minimum 12-month commitment to access their published rates. The only commitment-free option is Pay-as-you-Go, billed at a flat €0.35/minute with no included minutes. Zeeg is billed monthly by default, with an optional annual discount, and no forced long-term contract.
