PolyAI is positioned as enterprise dialog-agent platform with a builder, developer tooling and system integrations. Synthflow is positioned as a visual voice-agent workflow platform sold through scoped deployments and partner delivery. Start by deciding who owns the missing layers, then inspect the documented differences below.
Enterprise Platforms and Full Platforms are different product categories. An underlying engine or framework is not a complete substitute for a deployed agent workflow.
15 jointly documented catalog fields. This measures evidence coverage, not equivalent quality or an overall winner.
Test opening hours, booking conflicts and an unanswered transfer.

The evidence overlap.
Both records have documented values for Product type, Technical setup, Pricing model, DTMF, Call recording, ElevenLabs TTS, OpenAI models, MCP tools, Knowledge base / RAG, Function / tool calling, Transcripts, Analytics dashboard and additional fields shown in Compare. Matching availability does not measure behavior under your call conditions.
Run the same booking, tool failure and unsuccessful human-transfer cases. Record both outcomes and billable units before signing a deployment agreement.
