Knowledge to answer. Tools to act.
Add documents and website pages for the agent to answer from. Give it Tools to look up a caller, open a ticket, or call any API you connect with Custom Actions.
Each Tool says what the caller hears while it runs. Before a Tool changes something, the agent is told to confirm with the caller first.

Questions about AI agents.
How long does it take to set up an agent?
Minutes. Describe your business, pick a voice and confirm the basics, and the agent's persona and greeting are filled in. Then fine-tune it in the builder whenever you like.
Which languages does the agent speak?
English, Spanish and French, in eight locales: English (US, UK, Australia, New Zealand), Spanish (Mexico, Spain) and French (Canada, France). Each agent speaks one; route callers to a second agent with a phone menu.
What can the agent know?
Your documents (PDF, CSV, Markdown or text) and pages from your website, plus the role, rules and context you give it.
Can it work in my other systems?
Yes. Tools let it look up a caller, open a ticket or check a balance, and Custom Actions connect it to any API. Before a Tool changes something, it's told to confirm with the caller first.
Can I test it before it answers real calls?
Yes. Talk to your draft agent in the browser, as a known contact or a new caller, with Tools answering from sample data. Nothing goes live until you publish.
What if I change something and don't like it?
Roll back. Every publish is a version, and rolling back creates a new one, so history is never lost.
How is the AI billed?
Each plan includes AI minutes for the workspace: 60, 150 or 300 a month. Past them, 25¢ a minute. Only the time the agent spends on a call counts.
