The Agent Builder lets you create a production voice agent entirely from the dashboard. You write the system prompt, pick the models, attach tools and knowledge, and ship it to phone numbers or your app. You don’t write or host any code. Every change is versioned, much like a Git repository. You edit a draft, save it as a commit, test ideas on a branch, and deploy the version you want to go live.

Core concepts

​
How a change goes live

1

Edit

Change anything in the Agent or Pipeline tab. The header shows Draft auto-saved and a Draft badge.
2

Test

Use Start Test Call in the Preview panel with Current Draft selected to talk to your uncommitted changes.
3

Commit

Select Commit, review the diff, and add a description. This creates a new version on the branch.
4

Deploy

Select Deploy to make the committed version live, and optionally split traffic across branches.

Create an agent

Start from a template or from scratch.

Prefer code?

Build the same agent with the Python or Node.js SDK.
