This is a Genius B*tchwork post.
Most weeks I show you boring work my own AI did for me. This week I want to show you something a real person did, something that genuinely matters, so you can do the same thing if you ever need it.
I did not have doctors dismiss my paralysis for years and write anxiety on my chart. Phoebe Tesoriere did. And what ChatGPT found for her is the kind of thing that stops you cold.
Here is what happened.
Phoebe is 23 years old and lives in Cardiff, Wales. She started having seizures. Her hair was falling out. She lost feeling from her chest down. Over years of doctor visits, she kept getting the same answers: anxiety. Epilepsy. Nothing to explain the paralysis that was slowly taking over her body.
One afternoon she typed her full list of symptoms into ChatGPT.
It gave her a name: hereditary spastic paraplegia, also called HSP. A rare genetic disorder that damages the nerves that control movement in your legs.
She brought that name to her GP. She asked for a genetic test. The test came back positive. The diagnosis was confirmed. She now uses a wheelchair. After years of being told it was in her head, she finally had an answer.
That story was reported by Ladbible and WalesOnline, part of BBC coverage, in April 2026. (Link at the bottom.)
And here is the part that matters for you. Rare diseases affect more people than most of us realize. The average person with a rare disease waits years for a correct diagnosis. During that wait they are often told their symptoms are stress, anxiety, or something else that puts the blame back on them. AI cannot fix the whole medical system. But it can do something a tired, overworked GP sometimes cannot: sit with a long, messy, weird list of symptoms and look for patterns.
What years of the wrong answer costs
Phoebe lost years. That is not dramatic. That is just the math of a condition that was progressing while the answer was being missed.
For a lot of people with rare or complicated conditions, the story is the same. You go in with a list. You come out with something vague. You go home and search the internet and get scared. You go back. Same thing.
The internet search rabbit hole is not the answer. It is noisy, it is scary, and it does not know which symptoms matter and which ones do not.
What Phoebe did differently was give AI the whole picture and ask it to think out loud. Not "what is wrong with me?" but "here are all my symptoms, what conditions match this full list together?"
That is a better question. And AI is good at answering it.
What you get in this one
I broke down exactly how to do what Phoebe did so a total beginner can try it.
By the end of this post you will have:
The right way to build your symptom list so AI can actually use it.
The copy-paste prompt that asks AI to think through your symptoms like a differential diagnosis.
The follow-up prompt that helps you go deeper on anything that surprises you.
The prompt that helps you prepare for your next doctor appointment without sounding like you self-diagnosed on the internet.
The safety rules, because this one matters more than most.
You do not need any medical background. That is the whole point.
Quick and honest note before we start
AI is not a doctor. It does not have your medical records, your history, or the ability to examine you. It can surface possibilities, not certainties. Phoebe's story worked because she took what ChatGPT found and brought it to a real doctor who ordered a real test. That is the order of operations.
This is a starting point for a conversation with a doctor. Not a replacement for one.
Do not use this instead of emergency care. If you are having a medical emergency, call 911 or go to an ER. AI first is never the right call in a crisis.
