EVERY LOG MAKES EVERYONE SMARTER

The first superintelligence for type 1 diabetes.

You’ve dosed thousands of meals. So has everyone else here. Pool those logs, anonymize them, and you get something you can ask questions of. It answers with what people took and what their glucose did next.

how do people dose for a cilantro lime chicken bowl at Just Salad?
287 logs of that bowl. Most take 4u rapid about 15 minutes before and peak around 150. People who dose like you (low carb, half units) skip the rice and take 2u. Median peak 132, no late spike.

and if I add the tortilla chips?
Another 18g of fast carbs. People like you added 1.5u and went out to 20 minutes. At 15, the chips got there first.

Leave your email and we’ll let you in as spots open.

Every answer comes from a meal someone ate and a dose someone took, not from a label or a formula. The network is only as good as what goes into it, so logging a meal takes one line of text.

anonymized · opt-in · shared experience, not medical advice

One line. Two insulins.

Type took 1H and 2R. Betacell reads it as Humalog 1u and Regular 2u, stamps the time, and draws both curves. That’s the whole entry.

Four things standard advice gets wrong

Most diabetes advice stops at carb counting. Here’s what it misses, and what Betacell is built around.

20g of rice is not 20g of cauliflower

The label says 20g either way. Your meter disagrees. Starch breaks down fast and spikes you; non-starchy vegetables barely register. Betacell counts what a food does, not what the label says.

white rice, 1 cup45g · fast spike
sweet potato, 1 cup27g · moderate
cauliflower, 1 cup5g · barely moves

Protein needs insulin

You’ll hear that it doesn’t. About half the protein you eat becomes glucose over the following hours. Eat a 40g-protein steak with no cover and you get a slow rise late in the evening you didn’t plan for. Betacell shows you that curve and doses for it.

steak, 40g protein
protein → glucose · slow, peaks hours later

Small meals, small mistakes

Richard Bernstein’s law of small numbers: a 90g meal with a 12u bolus can be wrong by a lot. A 15g meal with 2u can’t. Keep the numbers small and the errors stay small.

It knows when you usually eat

Most days, thirty minutes after your bolus, you reach for the same yogurt. Betacell tells you when you’re there, so you don’t miss the window or stack a second dose on top.

Ask your own log

The answers are already in there

You don’t have to scroll to find one dinner from last week. Ask for it.

Ask how your insulin played out

A specific meal, a prebolus, a whole week. Ask in plain words and Betacell pulls it from your log and answers you straight.

how much did I prebolus for the edamame noodles with chicken last week?
Wednesday, 19:05 — 2u Regular, 25 minutes ahead. You peaked at 138 and were under 110 by 22:00. The time before that you only went 15 minutes and hit 164.

It tracks what’s still working

Humalog, Regular, Tresiba: different curves, and they overlap. Betacell flags what’s still active before you correct on top of it.

“1.8u still working. Skip this correction, or make it 0.5u.”

It remembers your meals

Log something once with its macros and your usual dose. Type the name next time and it all comes back.

We built this for our daughter

She has type 1. She’s between 65 and 140 about 95% of the time. Not 70 to 180, the range everyone else quotes. 65 to 140. Her last A1C was 4.8.

We get there with low-carb meals and a mixed bolus drawn by syringe. Everything in Betacell is something we already do at the kitchen table, every day.
