The Future Patient is a blog by patient survivor John Duffield who used AI to navigate, understand, and emotionally survive a complex medical journey.
Readers can expect personal stories, practical tools, and strategic insights on how AI can empower patients, improve communication, and transform the care experience. It’s a must-read for anyone: patient, caregiver, or clinician who believes healthcare should be more human, more connected, and more forward-thinking.
Hearts & Algorithms
John translates his personal health journey, from the shock of diagnosis to recovery and resilience, into a practical, empathetic AI tool that acts as a 24/7 personal health companion.
Hearts & Algorithms has revealed what patients truly need: clarity, emotional support, and confidence to navigate care. From making sense of a new diagnosis to managing fear during recovery, patients consistently asked for guidance that felt human...not clinical. Hearts & Algorithms helps patients prepare, understand, and feel less alone—proving that healing isn’t just physical, it’s emotional, too. Including:
Always-on empathy: AI-driven reassurance and emotional support, available 24/7—tailored to each patient’s stage of care
Clear explanations: Breaks down complex diagnoses, procedures, and test results into language patients and families can actually understand.
Simulated expert dialogue: Prepares patients with smart, conversational practice—so they know what to ask before the next appointment.
