How it works

From idea to live calls in days, not months.

01

We design your voice agent

Together we define the conversation flow, tone, language, and schedule for your specific use case.

02

We build and deploy

Custom prompts, phone number provisioning, dashboard setup, and integrations with your existing systems.

03

Your AI agent starts calling

You get transcripts, analytics, and insights in real time. Scale up anytime — no limits.

Built for real use cases

Already powering automated calls across healthcare, recovery, and customer success.

Healthcare & Eldercare

Daily wellness check-ins

Medication reminders, cognitive engagement, and meaningful daily conversations for elderly residents.

Margit.ai uses CallSia to call elderly Swedes every morning for meaningful conversation.

Recovery & Mental Health

Structured daily support

Progress tracking, crisis detection, and judgment-free daily support calls for people in recovery.

Refrain.ing provides AI support calls for people in recovery — private, judgment-free, always available.
