Powering the voice layer for the world's best AI agents

Your AI Can Think, Write, and Execute.
But It Can't Pick Up the Phone.

Your agent has 100+ skills. It browses the web. Writes code. Manages databases. But the moment a workflow needs a real phone call — a cart recovery, a lead follow-up, a booking confirmation — it goes silent.

"We recovered $23K in abandoned carts the first month. Callsy calls customers within minutes of abandonment — our team couldn't do that manually even if we tried."

"I added Callsy as an MCP tool to my OpenClaw agent in about 5 minutes. Now my agent can actually call leads and follow up — it's the missing piece for autonomous workflows."

"We white-label Callsy for our e-commerce clients. It's become our highest-margin service — and none of our competitors can match it. The setup is absurdly easy."

MCP (Model Context Protocol) is an open standard that lets AI agents connect to external tools. Think of it as a universal adapter. You don't need to understand it — just connect Callsy to your AI tool and it works.

Absolutely. Callsy's MCP server integrates directly with OpenClaw agents. Add it as a skill and your autonomous agent can create voice personas, initiate calls, and check outcomes — all within the agent loop.

Not at all. If you can type a sentence, you can use Callsy. Describe your call in plain English. For Shopify merchants, the integration is point-and-click.

Natural and conversational — not robotic. You choose from multiple voice profiles and customize tone, pace, and personality to match your brand.

Yes. You define the playbook — common objections, discount authority, escalation triggers. The agent follows your rules and can warm-transfer to a human at any point.

Callsy runs entirely server-side. Your API keys, customer data, and call recordings never touch the agent's local environment.

We offer a 7-day money-back guarantee on every plan. Try it, see the results, and if you're not convinced, you get every cent back.
