I'm an endocrinologist. I now recommend this to half my patients on day one. The plain-English summaries help non-tech parents enormously.

Claude
How was last night?
Used Nightscout
Pretty steady. You hovered around 110 mg/dL most of the night, with one quick rise around 4am that came back down on its own. No alerts. Time-in-range was 94%.

Claude
And the whole week?
Used Nightscout
78% time-in-range over the last 7 days — up 4 points from the prior week. Wednesday and Saturday were the rough ones, both after dinner.
About
What it does.
You already run Nightscout. B77 doesn't replace it — it connects your assistant to the instance you already have. Connect once, keep full ownership, and ask Claude or ChatGPT how your day looked, what your time-in-range is, or how last night went. Read-only by design; nothing is written back, nothing is stored on B77.
Try saying
Just type and go.

Was last night a rough one?

I stopped opening the Nightscout app entirely. I just ask Claude. Game changer for parents of T1D kids — I can ask 'how is she now?' from anywhere and get a real, thoughtful answer instead of just a number.

Took 30 seconds to set up. The weekly summary saves me real time at endo appointments. I just paste it into the doc visit.

Thanks Tom! The weekly summary view was specifically built for endo prep. Glad it's landing.

Wish it could text me alerts too. Otherwise — perfect. Way better than the existing apps for ad-hoc questions.

Alerts are on the roadmap for Q3 — appreciate the push.

Finally I can ask 'was last night rough?' and get a real summary instead of staring at a graph. The natural language layer is the killer feature.

My Type-1 partner and I both connected our instances. We can ask about each other. Honestly emotional in a way I did not expect.

Solid. Sometimes Claude over-explains, but I prefer that to under-explaining. 4 stars instead of 5 only because it cannot yet log carbs.

Q & A
Questions, answered.
Do I need a Nightscout account?
Yes. B77 talks to your existing Nightscout instance — we don't store glucose data ourselves. If you don't have one yet, the open-source community has setup guides for Heroku and Vercel.
Is my data private?
Your assistant talks directly to your Nightscout URL using a token you provide. Nothing is stored on B77 servers. You can revoke access from your Nightscout admin anytime.
Will it work for kids on Dexcom / Libre?
Yes — Nightscout is the data layer, so anything that uploads to Nightscout works (Dexcom G6/G7, Libre 2/3, MiaoMiao, Spike, Tomato, etc).
Does it support alerts?
Not yet. Today it's read-only — you ask, it answers. Push alerts are on the roadmap for Q3.
Can I see other family members?
Yes. Set up multiple Nightscout instances and ask: "How is Mira today?" — the assistant will pick the right one.
