Interactive Tools
GNL Explorers
Interactive tools that turn glucose data, insulin exposure, and activity into something you can actually explore. Each explorer is built around one of the four majors — and designed to help you find where you sit, not just what the average looks like.
What the GNL Explorers are for
The GNL platform is built on one principle: glucose data tells the truth. But raw data only becomes useful when you understand the mechanisms behind it. The Explorers are interactive tools that let you put in your own numbers and see what the evidence suggests should happen — so you can compare that against what actually does.
They are not calculators that tell you what to do. They are educational tools that help you build your own understanding of how insulin, activity, nutrition, and glucose interact in your body specifically.
How to use them
Start with the explorer most relevant to something you are already curious about. Use your own data. Compare the output against your CGM. The gap between the average and your reality is where the learning happens.

The explorers
Activity and Exercise Explorer
In the presence of insulin, exercise supercharges insulin action. This explorer calculates how much activity is needed to bring elevated glucose back towards range — based on your weight, your current glucose, and your insulin on board. Built around the evidence that aerobic exercise effects can extend up to eleven hours after activity ends.
AID Algorithm Explorer
Automated insulin delivery systems make hundreds of micro-decisions every hour. This explorer lets you trace the logic of the Control-IQ algorithm — understanding what inputs drive what outputs, and why the system behaves the way it does in different glucose scenarios. Built for people who want to understand their AID system, not just use it.
Hypo and Hyperglycaemia Explorer
Understanding what drives glucose below or above range is the foundation of self-discovery with type 1 diabetes. This explorer maps the common mechanisms behind hypoglycaemia and hyperglycaemia — and helps you identify which variables are most likely at play in your own patterns.
Exercise Carbohydrate Calculator — 30 Minutes
Before aerobic exercise, insulin on board is the hidden risk. This calculator estimates how much carbohydrate you may need for 30 minutes of activity — based on your current IOB, body weight, and exercise type. Built around the evidence on how aerobic exercise amplifies insulin action in type 1 diabetes.
More explorers coming
The GNL Explorer series is growing. Upcoming tools will cover insulin on board modelling, CGM accuracy interpretation, mealtime glucose response patterns, and more. Each one is built around the same principle: give you a framework to explore your own data, not a formula to follow.
