Why Bettie

Bettie exists because food is still the part of diabetes that takes the most mental energy. Not the hardest part medically — just the part where you have to stop and think every single time.

I wrote before about food being the last piece of the puzzle. CGMs, pumps, and closed-loop systems handle most of the day-to-day, but every time you eat, you are back to making a judgment call. How many carbs? How confident are you? What happened last time you had something like this?

That is true whether you are cooking at home on a Tuesday night, grabbing a takeaway after work, eating at a restaurant with friends, or trying street food somewhere you have never been. The context changes, but the question is always the same.

Most carb counting tools give you a number. That is useful, but it is only the start. What I actually wanted was something that helped me build confidence over time — not just an estimate for this meal, but a way to look back and see what actually happened. Which meals kept me steady? Which ones surprised me? What changed when I adjusted?

That is what Bettie tries to do. It gives you a fast estimate through whatever method is easiest — photo, barcode, receipt, or just typing it out — and then connects that meal to your glucose data. Over time you end up with a personal history of what works for you, not just a generic nutrition database.

We also built the chat assistant because AI estimates are not always right, and a single number with no way to question it is not that helpful. If the portion looks wrong, or you had bread on the side, or you are eating something unfamiliar, you should be able to say that and see the estimate update. The goal is a result you trust, not just a fast one.

I think the real value shows up after a few weeks. You start to see patterns. You notice that your Tuesday pasta is reliable but Friday takeaway is all over the place. You find that a meal you were nervous about actually landed fine. That kind of feedback makes the next decision easier. Less guesswork, more confidence, less time spent thinking about it.

Bettie is not trying to change what you eat. It is trying to make the part where you figure out the carbs feel less like a chore and more like something that just happens. I want food to feel as handled as the rest of the system.
