AI agents

Create an AI voice agent in minutes: name, niche, prompt with CRM variables, a live voice catalog and LLM model — webhooks and in-call tools are wired for you.

Every prompt save creates a new version. Compare two versions line by line, judge them on real call metrics — calls, booked, conversion, average duration — and roll back with one click.

Tune your agent's voice (live from your Retell account), LLM model, language and behavior sliders, see the cost and latency estimate, and use the Advanced JSON hatch and the voicemail default.

Talk to your AI agent from the browser with your microphone — no phone number needed. Live transcript, a Tools invoked timeline, a simulated calendar, and the test lead for a real call.

Per-agent call policy: a per-day retry plan, an instant first call, real scheduled callbacks with their own follow-up rule, voicemail behavior and transfer to a human number.

Choose which numbers each agent dials from, and check they are registered on Retell. Assignment is fail-closed: an agent with zero assigned numbers never calls.

Each agent is outbound or inbound, and you state the pairing yourself: the inbound agent lists the outbound agents whose call-backs it answers. No number and no matching niche required.

Give an agent its own hours and days, pick which time zone they apply in — fixed, the sub-account's or each contact's — and decide whether the first call and agreed callbacks may step outside it.
