## Overview

Retell AI is a production-focused platform for automating phone conversations with AI voice agents that sound natural and respond quickly. The company reports roughly 600ms conversational latency and a proprietary turn-taking model, which keeps exchanges feeling fluent rather than robotic. Agents can be reached over voice, chat, and SMS, or embedded through an API.

The platform is built as a no-code studio: you design call flows on a drag-and-drop canvas, add functions, integrations, DTMF input, SMS steps, and escalation paths, then test changes with manual runs or large-scale simulations before deploying. Once live, you can monitor calls in real time, take over a conversation when a human touch is needed, and QA up to 100% of calls to measure agent quality at scale.

Retell targets real contact-center complexity — routing and warm transfers, outbound dialing campaigns, voicemail handling, IVR menu navigation, CRM context and write-back, plus custom analytics built from any post-call metric. Enterprise buyers get HIPAA, SOC 2 Type II, GDPR, and ISO 27001 compliance, SSO, role-based access, personal-data redaction, and deployment options including on-prem.

## Pricing & Plans

Retell AI offers a free trial and usage-based plans, with custom enterprise pricing available through a sales conversation. Public pages direct teams to book a demo for volume pricing and implementation support.

## Key Features & Capabilities

- **Drag-and-drop agent builder:** Design multi-step conversations visually, adding functions, integrations, call transfers, DTMF, SMS, and custom logic without heavy engineering.
- **Outbound campaigns at scale:** Upload audiences, schedule calling campaigns, control pacing and retries, and let AI agents dial and handle voicemail automatically.
- **Live monitoring and human handoff:** Listen to AI calls in real time and let human agents step in instantly, with agentic briefings before the transfer completes.
- **Post-call QA and custom analytics:** QA up to 100% of conversations, build analytics from any post-call metric, and compare agent versions with A/B testing.
- **Enterprise compliance and security:** HIPAA, SOC 2 Type II, GDPR, and ISO 27001 compliance, SSO, role-based access, personal-data redaction, and on-prem deployment options.

## Primary Use Cases

- **24/7 AI reception and triage (Customer support leader):** Route and answer inbound calls around the clock, resolve routine questions with a knowledge base, and hand complex cases to humans.
- **Automated lead qualification (Sales operations manager):** Run outbound campaigns that qualify, book appointments, and write outcomes back to the CRM without adding headcount.
- **Patient scheduling and reminders (Healthcare operations):** Handle appointment booking, confirmations, and follow-ups under HIPAA-compliant controls.
- **IVR navigation and call routing (Contact center engineer):** Let agents detect keypad menus, press digits, and reach the right destination inside existing phone systems.

## Strengths

- Human-quality, low-latency voice with a strong turn-taking model
- No-code flow design that lets internal teams iterate without vendor help
- Broad compliance coverage (HIPAA, SOC 2 Type II, GDPR, ISO 27001) plus SSO and on-prem options
- Strong observability: live monitoring, call takeovers, and full-call QA

## Limitations

- No transparent public pricing; costs require a sales conversation
- Advanced contact-center workflows can take time to configure well
- Highest value depends on making several integrations (telephony, CRM) work together
