Retell AI is a voice agent platform for automating phone calls. Teams build agents on a drag-and-drop canvas, add functions, call transfers, DTMF, SMS and custom logic, then deploy them for inbound calls, outbound campaigns, web or SMS. Retell quotes roughly 600ms latency, a proprietary turn-taking model and realistic voices. Pricing is pay as you go at $0.07 to $0.31 per minute for voice agents and $0.002 or more per message for chat agents, with an Enterprise plan on custom pricing.
Call center leaders, operations teams, healthcare providers and developers are the target users. Because the studio is no-code, non-engineers can update agents without waiting on Retell, while developers get API and webhook access. Enterprise buyers can look at SSO, role-based access control, PII redaction, HIPAA support and on-prem options. Case studies include Pine Park Health, which raised scheduling NPS by 38 percent, SWTCH, which handles urgent EV support, and Medical Data Systems, which handles all inbound calls with a 30 percent transfer rate.
Use cases on offer in the live demo include receptionist, appointment setter, lead qualification, customer service, debt collection and survey agents. Agents can detect IVR menus and press digits, brief a human agent before a handoff, and run outbound campaigns with scheduling, pacing, retries and voicemail handling. Supervisors can listen live and take over a call. Before launch, teams simulate thousands of scenarios and convert real production calls into regression tests, then measure quality by reviewing up to 100 percent of calls and comparing agent versions through A/B tests and custom post-call analytics.
