T1D care you can talk with

Tell Claude or ChatGPT what’s on the plate and the carbs reach Loop and the school nurse. Ask it anything at 2am: an AI endo has been watching every high and low.

A meal, start to finish

remember: a slice of school pizza is 30g of carbs

Saved to Liam’s carb book: school pizza, 1 slice = 30 g.

The daily digest

TalkT1 · to you · 8:05 AM
Liam · 3 things to do, in order

The picture. Two separate, related things. Loop is correcting from inside its range, and those corrections are ending in lows — that is the correction range, which is set too low to leave room. And when Loop does correct, it overshoots — that is the ISF, which is set too strong. Raising the range stops the corrections that should not happen; raising the ISF number makes the ones that do smaller.

1
Raise the correction range. 100–115 → 110–125. Corrections from inside it are ending in lows. Loop › Therapy Settings › Correction Range
2
Weaken the ISF. 00:00–06:00: 130 → 143 mg/dL/U (+10%). Each correction gets smaller. Loop › Therapy Settings › Insulin Sensitivities
3
Low around 10:00 on school days — recess?. Add a “Recess” preset, on by 09:00: correction range 150–165, Overall Insulin Needs 50%. Loop › Overrides › +

Nothing changes until you make the change. Not a medical device.

Say what’s on the plate

Tell Claude or ChatGPT what’s for lunch: out loud in voice mode, typed, or as a photo. It works out the carbs from your weights.

An AI endo, around the clock

Each high and low gets a note on its likely cause. Repeats become patterns; it suggests a change only when the evidence holds up.

Texts from your number

The school nurse gets lunch’s carbs at the time you choose, sent by your own Mac.

Nothing reaches the pump on its own: you get a link, and one tap on that link sends the meal to Loop; a second delivers the dose Loop worked out. See everything it can do.
