Sally vs ChatGPT and Claude: Which One Should You Ask About Your Blood Sugar?
General chatbots explain health. Sally reads your own data. Here is when to ask which.
ChatGPT, Claude and Sally can all answer a question about blood sugar. They do it from different starting points, and the difference decides which one to ask.
| General chatbot (ChatGPT, Claude) | Sally in A1C Insights | |
|---|---|---|
| Starts from | Nothing each time, unless you type your history into the chat | Your own data |
| Data it uses | What you type or paste in | Glucose from a sensor if you wear one, plus sleep, activity, food you log and lab reports you upload |
| Remembers | Only what is in the chat | What you saved |
| Best for | Learning a topic | Applying it to your own week |
| Can diagnose you or set your medicine | No | No |
What does a general chatbot do well?
A general chatbot knows a great deal about health in general. It explains what HbA1c means, why a meal raised your glucose, or what to ask your doctor. It can read a lab report you paste in. It is a good place to learn.
What it does not have is you. It starts from nothing each time, unless you type your history into the chat.
What does Sally do differently?
Sally is the AI inside A1C Insights. Sally works from your own data: your glucose from a sensor if you wear one, plus sleep, activity, food you log, and lab reports you upload. Sally remembers what you saved, so the answer to "why was Tuesday bad?" starts from your Tuesday.
Sally's answers draw on the A1C Almanac, a library of research articles that A1C maintains. The chat shows its reasoning and the sources it used.
Which one should you ask?
Ask a general chatbot when you want to learn:
- What does a fasting glucose of this number mean in general?
- What is insulin resistance?
- How do I prepare for a talk with my doctor?
Ask Sally when you want it applied to you:
- Why did my blood sugar rise after the same breakfast on two different days?
- Did my short night change this morning's reading?
- What changed in my week compared to the week before?
What can neither one do?
Neither can diagnose you. Neither should set your medicine. A1C Insights is an app, not a medical device. For anything that touches a diagnosis or a dose, your doctor decides.
Using both
Many people will use both. Learn the topic in a general chatbot, then open Sally to see how it plays out in your own week. They do not compete for the same job.
What you still control
Whichever you ask, the answer only helps if you act on one thing. Pick one small change from the answer, such as a walk after dinner, try it for a week, and look at the result.
