💡 Pro tip: Most tools offer free trials or free tiers. Test 2-3 options side-by-side to see which fits your workflow best.
PolyAI does not publish pricing — it is sold under custom enterprise contracts negotiated through its sales team based on call volume, languages, integrations, and channels. Industry references typically place deployments in the six- and seven-figure annual range, comparable to other enterprise contact-center AI vendors. Customers should expect a discovery call, scoped pilot, and SOW before pricing is finalized. There is no free tier, free trial, or month-to-month option visible on the site.
PolyAI is omnichannel: a single agent built in Agent Studio can be deployed across voice (inbound phone), web chat, and SMS without rebuilding the underlying logic. The platform plugs into existing contact-center stacks like NICE and Genesys for telephony, and CRMs like Salesforce for customer data. This unified approach is one of PolyAI's main differentiators versus voice-only or chat-only competitors. Channel routing and escalation rules are configured centrally.
PolyAI targets enterprise contact centers with a managed, full-service deployment model, while Vapi and Retell AI are developer-first APIs where engineers build voice agents themselves. PolyAI includes Agent Studio, professional services, pre-built CRM integrations, and compliance controls out of the box; Vapi/Retell give you primitives and lower per-minute pricing but expect you to architect, host, and maintain the agent. Choose PolyAI for Fortune 500-grade rollouts; choose Vapi or Retell for fast, low-cost prototyping.
PolyAI supports dozens of languages and dialects, including English, Spanish, French, German, Italian, Portuguese, and less-commonly-supported languages like Croatian — which it deployed for Zagrebačka banka so customers could self-serve in their native language. Voices are tuned for naturalness rather than just accuracy, which is why customers like Audibel cite them as sounding like 'one of our own agents.' Multilingual deployments can run from a single agent definition. Specific language availability should be confirmed during the sales discovery process.
PolyAI's published customer roster spans regulated and high-volume industries: utilities (PG&E), healthcare (Howard Brown Health), hospitality (Fogo de Chão, hotel and casino brands), banking (UniCredit, Zagrebačka banka, Quicken), hearing-aid retail (Audibel), and global delivery. The common thread is high call volumes, a need to preserve brand voice, and tight compliance or escalation requirements. Documented results include CSAT lifts, multi-million-dollar revenue contributions, and 50%+ call-containment rates. It is not designed for individual developers or small startups.
