Sword Health's Chapter 2 update blends AI with human therapists in real-time chats

Sword Health is rolling out a major update to its app, codenamed Chapter 2. The redesign introduces a three-way chat feature connecting users, the AI assistant Phoenix, and their physical therapist. The goal is to make digital interactions feel more natural and human-like.

Product Manager Catarina Farinha recently discussed the changes on *Expresso*'s *The Future of the Future* podcast, highlighting how the company blends technology with human oversight.

The updated app will allow Phoenix to engage in conversations that mimic real human uncertainty. When the AI encounters questions beyond its scope, it will seamlessly bring a physical therapist into the chat. This ensures users receive accurate guidance while maintaining a personal touch.

Sword Health stresses that clinical decisions remain in the hands of human professionals. Phoenix operates under strict guidelines, clearly distinguishing between issues it can handle and those requiring expert input. The company describes this as a *human-in-the-loop* approach, where AI scales access to care but defers to clinicians for critical assessments. The redesign reflects Sword Health's broader strategy of using AI to expand reach without compromising quality. By integrating therapists into digital interactions, the app aims to balance efficiency with the nuanced judgement only humans can provide.

The new three-way chat system will launch as part of Sword Health's Chapter 2 update. Users will interact with both AI and therapists in real time, ensuring support remains responsive and clinically sound. The company continues to refine how technology and human expertise work together in digital healthcare.
