Retell AI Launches Conductor

Retell AI, an artificial intelligence voice agent platform provider, has launched Conductor, a graph-native review system for production voice agents.

Conductor is an AI copilot that understands how voice agents actually run. It shows every proposed change right inside the agent's workflow, and it never makes a change until a person approves it. Conductor helps companies build, create simulation tests, analyze calls, and continually improve the AI voice agents that power their contact centers. Conductor works inside the workflow itself, so it understands what each change touches and what it might affect downstream.

Teams interact with Conductor using plain English. A request, such as "Test edge cases and fix the agent," or "Review recent calls and update the agent," and Conductor proposes the review change.

Conductor already generates 70 percent of Retell's simulation tests and executes half of all agent edits used by Retell's own engineering teams. Conductor packages thousands of real-world customer deployments and best practices into a single operationally aware system that helps teams build, test and continuously improve voice agents through an intuitive interface.

"Generic copilots weren't enough," said Bing Wu, co-founder and CEO of Retell AI, in a statement. "Building production-ready voice agents is far more complex than generating prompts or making isolated edits. Every change can impact customer experiences in unexpected ways. We built Conductor to think like an expert operator, not a generic assistant."

Conductor shows each change on the step or setting it affects, inside the agent's workflow. Users see a clear before-and-after, move through changes one at a time, and open a detailed line-by-line view. The user can accept or reject each change on its own or all at once and undo any decision with one click. Nothing goes live until it's approved.

Conductor also has guardrails built in. It won't apply a change to the wrong agent, and if something can't be applied, it clearly identifies the issue instead of leaving the agent half-finished. Nothing ships to production without someone approving it first.

Conductor builds agents faster and improves them more safely, so teams can keep changing a live agent without worrying that the next edit will quietly break something for a customer.

Voice agents are interconnected systems where even minor edits can unintentionally create downstream issues. Conductor reviews failed calls, generates simulation tests to reproduce the failure, and surfaces the fix as a reviewable proposal.

Conductor can be directed to a failed call, a specific workflow step, a saved test case, or a file to generate targeted recommendations. It reads exactly what happened and tailors its advice to that situation. Organizations gain access to deployment frameworks, optimization techniques, and operational knowledge that previously required specialized teams. Conductor further strengthens the Retell platform as companies move from AI experimentation to production-scale deployment.

"Most AI tools help you build something once," Wu said. "Conductor helps you operate, improve and scale voice agents every day after launch. That's where the real challenge begins."

Retell AI's no-code platform enables companies to deploy human-like AI voice agents in days rather than months, powering real-time call automation across healthcare, logistics, financial services, real estate, and customer support. The platform processes more than 30 live calls per second and now handles more than 55 million AI phone calls each month.
