PolyAI

PolyAI builds dialog agents that handle the most critical enterprise conversations, resolving them without escalation. Its homepage calls conversation the interface to everything: teams design adaptive agents in Dialog Studio, build them, run them on PolyAI's own models, and connect them to the systems they already have, so the same agent can run on every channel customers use. The platform runs on state of the art dialog models continuously trained on hundreds of millions of real business interactions and scored in the open on Dialog-Eval, its independently judged benchmark. Its flagship model, Dialog-RSN-1, reasons directly over raw call audio for turn taking, recognition, and response in one audio native model, with under 300ms model response, 89.8 turn taking accuracy, and a 3.7 percent word error rate as published on the homepage. A second model, Dialog-RAVEN-3.5, is a text based cascade for webchat and multilingual work, carrying the same agent across chat, SMS, and messaging. At enterprise scale, PolyAI reports that 90 percent of calls are resolved end to end with no human agent on its largest deployments, hundreds of millions of calls per year, 99.994 percent uptime over the trailing twelve months, and capacity for 10,000 concurrent calls. Pre-built integrations, a self serve Connect Portal, and open APIs connect agents to existing stacks, with Microsoft Teams, Slack, Zoom, ServiceNow, Zendesk, Twilio, NICE, and Dropbox shown among its integrations. Resilience and governance run around every interaction. PolyAI lists SOC 2 Type 2, ISO 27001, PCI DSS, and GDPR certification, SIP/TLS and SRTP encryption, mTLS, SSO and role based access, data residency across the US, UK, EU, and APAC with no cross region transfer, guardrails, PII redaction, and human in the loop controls. Customer data is never trained on without opt in and never sold. PolyAI suits enterprises whose phone conversations are critical, regulated, or high volume, and who want a dialog agent that resolves the request inside the call instead of escalating it.

Retell AI

Retell AI

Retell AI is an AI voice agent platform for contact centers, in production at more than 4,000 businesses according to its homepage. Its agents answer inbound calls and place outbound calls, qualify leads, book appointments, check order status, and route or transfer callers to a live agent when needed. Retell is built for real contact center demands such as transfers, phone trees, outbound volume, and back end systems that have to work on every call. Features include agentic warm transfers, where the agent briefs the receiving person before connecting the customer, IVR navigation through complex phone trees and extensions, and a mix of deterministic and generative responses so critical steps such as disclosures and verification follow exact requirements while the rest of the conversation stays natural. During a live call, Retell agents can execute custom logic, access real time data, and complete tasks across business systems, from booking appointments to updating records. Persistent memory keeps a running brief on every contact across calls and texts, so returning callers can pick up where they left off. The platform also offers burst concurrency, sentiment analysis, AI quality assurance, live monitoring, and a shared caller history that can sync with an existing CRM or run in Retell CRM. CX teams build agents in a no code studio while developers extend them with APIs and SDKs, and every call is transcribed for review. Retell cites response times around 600 milliseconds and compliance with HIPAA, SOC 2 Type II, GDPR, and ISO 27001, with SSO, personal information redaction, and role based access control. On its pricing page, Retell describes true pay as you go pricing for voice agents at $0.07 to $0.31 per minute depending on the models, voice, and add ons chosen, with enterprise pricing custom, no platform fee, and 20 concurrent calls included. New accounts receive $10 in free credits on signup according to the homepage.
