PolyAI vs Smith.ai Comparison (2025)

PolyAI
Starting at $0.25 /min (example case study)
Poly AI positions itself as a multilingual powerhouse with natural-sounding agents and enterprise use cases. But without public pricing, you’ll need to talk to sales before understanding costs—and anything outside standard English can trigger custom pricing. Integrations work fine if you’re on Salesforce or a mainstream stack, but anything else means custom development. In real use, the assistant occasionally forgets context or asks you to repeat yourself, which breaks the illusion fast. For all the polish, it often feels like a heavy lift to get consistent, high-quality performance.
