Bett-i by Betterness
Your 24/7 AI coaching team.
Free · Designed for iPad. Not verified for macOS.
Your AI coaching team. Always on.
Bett-i is your personal team of AI specialists. Talk to it anytime — by voice, text, or phone — and it helps you sleep better, train smarter, track your bloodwork, and actually stick with it. It's not a chatbot. It's a continuously running team that orders labs, interprets your results, adjusts your plan, and checks in on you — always under your consent, always on your side. And when you want your own expert for a specific goal, you can build one, give it knowledge and a voice, and deploy it in minutes.
Talk to your own coaching team.
Specialists across nutrition, sleep, training, recovery, longevity, hormones, and fertility — summoned by voice or text. Each one shares context with your full health picture, so you get coordinated guidance, not generic chatbot answers. Bett-i remembers your goals, routines, and progress across every conversation.
Build your own specialist. In minutes.
The fastest agent builder on the market. A guided wizard walks you through persona, capabilities, knowledge, and voice — no code, no prompt engineering. Upload PDFs, lab results, or your own protocols; the agent learns from exactly what you give it. Pick from 40+ voices or bring your own. Generate an avatar. Deploy it as private or share it with your audience.
Goals that adapt to your biology.
Don't write goals from scratch — Bett-i proposes them based on your biomarkers, wearable data, and history, then routes each one to the right specialist. Biomarker-linked progress, adaptive check-ins when your HRV or sleep shifts, and a Daily Actions plan that breaks goals into the next thing to actually do.
Order labs. Understand your numbers.
Order blood panels and biomarker tests directly in the app through Quest Diagnostics and LabCorp (via licensed third-party partners). Bett-i reads your results in the context of your full health profile — not just reference ranges — and flags what's worth your attention.
Wearables that finally add up.
Connect Apple Health, Oura, WHOOP, Garmin, Withings, Eight Sleep, and more. Bett-i watches your trends and flags dips in sleep, unusual heart-rate patterns, or missed targets before you notice them yourself — with proactive alerts when something moves.
Check-ins where you already chat.
Bett-i reaches you on WhatsApp and Telegram — not just inside the app. Morning brief, lab results, goal reminders, and recovery nudges land in the messaging app you already live in, so you never have to remember to check another thing.
A coach for your real life.
Training for a marathon? Bett-i layers endurance biomarkers and recovery protocols. Planning a pregnancy? It pivots to preconception optimization. On a GLP-1? It watches the markers that matter. Real context, real adjustments.
Your private knowledge base.
Upload lab results, health records, PDFs, and documents to your private knowledge base. Bett-i grounds every answer in your actual data. Long-term memory learns your routines and preferences, so guidance gets sharper over time — and so do the agents you build.
Private by default.
HIPAA-grade governance. Every tool call, every agent interaction, and every piece of context is logged, scoped, and revocable. Your data is never sold.
Who it's for.
Anyone who wants smarter, more personal health guidance backed by their own data. Individuals optimizing sleep, training, longevity, and recovery. Coaches, practitioners, and creators who want to build their own AI specialist and share it with an audience.
Bett-i is made by Betterness. In pursuit of Betterness — for everyone, every day.
