Root Wellness Labs

AI models & experiences for wellness companionship

AI companions for change that takes root.

Root Wellness Labs designs and trains open-source wellness companion models — language, agent and vision — that run privately on your own computer or a lightweight home server. Your health data stays yours while you eat better, move more and stay accountable with a small community.

Root Companion · evening check-in Preview
You've hit your protein goal four of the last five days. Tonight's dinner photo looked light on greens — want a two-minute swap for tomorrow?
Yes. And remind me about the walk with my circle.
Done. Three people from your circle are walking at 7:15 — I'll nudge you at 6:45.

The problem

The most personal data deserves the most private AI.

Real wellness coaching needs real context: your goals, progress photos of your body, bloodwork results, medical history. That is exactly the data people are most reluctant to hand to a cloud service — and least willing to see turned into advertising.

So people either share too little to get useful help, or share it and lose control of it. We think there's a better option: purpose-trained, open-source models that live on hardware you own, remember your goals, and never need to send your data anywhere.

Products

Our models, and the experience they power

Three open-source model families, each trained for one job and sized to run at home, working together inside one companion experience.

The Companion

The consumer experience: daily check-ins by text, voice or photo, personal insights and small peer circles — powered by all three models, running on your own computer or home server.

What the companion covers

Six domains our models are trained and evaluated on — where small, consistent changes compound.

Microcommunity

Small circles of people with similar goals, matched and supported by the companion so nobody drifts alone.

Whole-person wellness

Sleep, stress, energy and mood treated as one connected system rather than separate apps and scores.

Nutrition

Snap a meal, get honest context and one practical next step — built around how you actually eat.

Exercise

Plans that adapt to your week, with form feedback from Root Vision and a circle to train alongside.

Peptides

Clear, sourced summaries of emerging research — what's known, what isn't, and questions worth bringing to your clinician.

Emerging trends

New protocols and wearables, weighed against the evidence before they reach anyone's plan.

Technology

Open models, trained on GPUs, built to run at home

We combine frontier AI infrastructure experience with the fast-growing open-source model ecosystem. We train on NVIDIA RTX GPUs, then optimize every release to run on the consumer GPUs and lightweight servers people already own.

  1. 01 · Data

    Curated wellness corpora

    Coaching dialogues, nutrition and exercise literature, and labeled meal and movement imagery, gathered with consent.

  2. 02 · Train

    Fine-tuning on our GPUs

    Open foundation models adapted for coaching, vision and planning on NVIDIA RTX hardware, scaling to RTX PRO-class GPUs.

  3. 03 · Evaluate

    Safety-first benchmarks

    Every release is tested for accuracy, tone and safe escalation — the companion knows when to point people to a professional.

  4. 04 · Deploy

    Runs on hardware you own

    Compressed and optimized open weights for home computers and lightweight servers, so photos, labs and conversations never have to leave the house.

How we build

Principles behind every release

Community over content

People change alongside people. Our models exist to keep small groups connected and consistent.

Evidence before hype

Trends are weighed against the research, and the companion says plainly when the science isn't settled.

Private by design

Your health data stays on your hardware. No ads, no data sales — open models you can run, inspect and trust.

Support, not substitute

The companion complements doctors and coaches — it never diagnoses, prescribes or replaces professional care.

Company

About Root Wellness Labs

Root Wellness Labs was founded by Samuel Hsiung to answer a simple question: how do you get truly personal wellness guidance without giving up your most personal data?

Our answer is to design and train open-source models that people run locally, on a home computer or a lightweight server. We bring years of experience at the frontier of AI technology and infrastructure to the open-source ecosystem, and turn it into wellness companions people can actually trust.
