Retell AI

Retell AI is a platform for building, deploying and managing AI voice agents that automate phone calls. Its agents are designed to sound human, carry out tasks and scale with call volume. Common use cases include receptionists, appointment setting, lead qualification, customer service, debt collection and surveys. You can request a live demo call from one of its agents on the website.

No-code studio

Retell offers a production-ready studio your team can operate itself, so you can build, update, test and deploy voice agents without relying on Retell for every change. Complex call flows are designed visually on a drag-and-drop canvas, where you add functions and integrations to each step of the conversation. The platform covers building, testing, deployment, QA and analytics.

Case studies

Retell shares several customer results. Pine Park Health says it increased scheduling NPS by 38% and filled underused provider capacity. EV charging company SWTCH says its agent answers calls in seconds, handles urgent support at scale and cut support costs by over 50%. Medical Data Systems says it handles 100% of inbound calls with a 30% transfer rate and collects about $280,000 a month. These are customer-reported outcomes.

Pricing

Retell uses true pay-as-you-go pricing without annual contracts. You go live with $10 in free credits and full platform access. AI voice agents cost $0.07 to $0.31 per minute, and AI chat agents cost from $0.002 per message. Pay-as-you-go includes pre-built agent templates, call analytics and transcripts, simulation testing, webhooks and API access, 20 free concurrent calls, and community and email support. An Enterprise plan offers higher reliability, tighter compliance, dedicated support and volume pricing.

Who it suits

It suits businesses and developers that want to automate phone calls without committing to a large contract before testing.

Things to consider

Per-minute costs depend on the voice, model and telephony options you choose, so estimate total cost at your volume. Disclose AI use to callers where required, and follow rules on automated outbound calls, recording consent and debt collection. Plan clear transfers to humans for complex or sensitive calls.

Because agents can call functions and integrations mid-conversation, they can check calendars, look up accounts or update records while on the phone, instead of only taking messages for a human to follow up later.
