PolyAI

PolyAI is a voice specialist rather than a general AI platform, and the difference shows in the hardest part of the job: understanding real callers who interrupt, change their minds, speak with strong accents or call from noisy places. With over $200M raised it serves large hotel groups, healthcare providers, banks and utilities, handling reservations, patient scheduling and account enquiries at contact-centre volume with detailed analytics and containment reporting. This is a deployment, not a signup — expect professional services, weeks of design and enterprise pricing. For a single-location SMB it is entirely the wrong product; for a brand where a poor phone experience damages reputation at scale, it is among the two or three credible options.

Best-in-class at the genuinely hard part of voice AI — understanding real callers rather than cooperative ones. That engineering only matters at volume, so it is the right choice for enterprises and completely wrong for an SMB, where the implementation alone would cost more than a decade of Rosie.
