Callers lets you build AI agents that hold real conversations with your customers: phone calls (outbound and inbound), text messages (SMS and WhatsApp), email, and voice or text chat on your website. You design the agent in the dashboard without writing code, then connect it to your systems with webhooks, the App Center, the REST API, or the Web SDK. Each agent follows a script you control, answers questions from your knowledge base, calls your systems during the conversation, and reports the outcome of every conversation in a structured format.

​
How Callers works

Contacts arrive by CSV, API, triggers, or inbound calls and messages; the agent follows its script, handles off-script questions with scenarios and the knowledge base, runs actions in real time, and every conversation ends classified against your success criteria with key questions answered and the result sent to your webhooks or CRM.

One agent, one conversation, on the channel each customer prefers: email, a phone call, or WhatsApp.
