From the page. cartesia.ai, captured Oct 8, 2026

We’re building self-service tools for patients, just in the channels they prefer to communicate with healthcare providers - phone and sms. The latency is there. It sounds realistic. It can actually handle crazy complex edge cases and unstructured inputs from the customer or from the patient, which wasn’t possible until today and still isn’t possible with all CcaaS providers.
