The honest brief
PolyAI
An end-to-end managed contact-center agent on its own Raven model — not a developer toolkit you assemble from telephony, LLM, and TTS parts.
- Handles complex multi-turn calls
- Enterprise compliance built in
- No-code studio plus developer ADK
- 2,000+ live deployments, 45 languages
- Custom enterprise contracts only
- No self-serve or SMB tier
- No public pricing
Retell AI
Bring your own LLM behind the voice agent, so it isn't locked to a single model like most all-in-one voice platforms.
- Inbound and outbound call handling
- SIP/Twilio telephony built in
- Low-latency turn-taking model
- No-code builder plus API
- Per-minute costs stack with LLM/TTS
- Voice quality depends on chosen vendors
- Cloud-only, no self-host
