Agentic Patient 9: She built an AI companion for breast cancer patients - and won't upload her records to ChatGPT
Faces of Digital HealthShow Notes
"I am actually quite wildly uncomfortable with patients using LLMs." She built an AI companion for breast cancer patients — and she means it.
Ellyn Winters-Robinson was diagnosed with breast cancer in March 2022, months before ChatGPT launched. She wrote a book about it on her iPhone during chemotherapy. That book became AskEllyn, an AI companion used across a hundred countries. In this episode of The Agentic Patient — a Faces of Digital Health series on how patients actually use AI, which prompts, which guardrails — she talks to Tjasa Zajc about what an AI companion can hold that a clinician cannot, and why she still worries about where patient data goes.
Guest: Ellyn Winters-Robinson, CEO of The Lyndall Project and AskEllyn, author of "Flat Please Hold the Shame"
What the conversation covers:
- Building an AI companion from a book written on an iPhone during chemotherapy
- Why she keeps AskEllyn strictly non-medical, and how that guardrail held up under health-insurer review
- Whether one woman's lived experience can support patients with different cancers, cultures and languages
- Why traditional cancer support groups can become "places of collective trauma"
- Scanxiety, and what happened when she used her own chatbot during a CT scare
- Why she is uncomfortable with patients uploading medical records to ChatGPT or Claude
- Patient data rights, desperation, and the risk of being "victimized again" by AI tools
- The Canadian Cancer Society-funded study now testing whether AI companions actually help
- "The patient is the workflow" — lived experience as an untapped resource in health system design
- How clinicians can coach patients to use AI safely instead of pretending they aren't
