Strong evidence
Multiple high-quality human trials and meta-analyses converge on a clear effect.
Creatine. Iron in deficiency. B12 in deficiency. Plant sterols.
The on-device health platform
The questions your doctor doesn’t have time to ask.
Almavivo runs the health-planning conversation that doesn’t fit in a 10-minute appointment. It weighs the human evidence honestly, builds you a personal plan, and keeps every answer on your device. No account, no server, no profile. We don’t even take your email address.
Your answers are built into a plan in your browser. No account, no upload, no third-party scripts. How we prove it →
Built on the evidence base of the NIH Office of Dietary Supplements, Cochrane reviews, and PubMed-indexed human trials.

A plan, not a shopping list.
What an Almavivo report looks like at the end of the intake. Lifestyle anchors come first, supplements come last, chosen to support the rest, not replace it.
Every recommendation carries an evidence tier. Every exclusion carries a reason. Patterns the engine notices in your answers are named, so you can see why the plan looks the way it does.
Why this matters
Most fatigue isn’t mysterious.
It’s sleep, food, movement, stress, or sometimes a real deficiency. Almavivo works through them in order of likely impact, and gives you a plan instead of a guess. Every recommendation carries an evidence tier so you can see how strong the case behind it is.
Reasonable evidence
Supportive human trial data with some inconsistency or narrower indications.
Magnesium. Omega-3 EPA/DHA. Melatonin. Riboflavin for migraine.
Mixed, traditional, or emerging
Smaller trials, narrower use cases, or long traditional use without modern RCTs. We label these honestly so you can decide.
L-theanine. Glycine. Ashwagandha. Reishi.
Why this is different
Most health quizzes are funnels for your data.
They look like a quiz, but every answer you give is sent to a server, stored, and tied to your name. Meanwhile the trackers running on the page quietly log your visit to your Google, Meta, X, and TikTok profiles in the background. Almavivo is built so that simply can’t happen.
Most health quizzes
- Store your intake answers from question one.
- Build a profile attached to your name and email.
- Run dozens of trackers, pixels, and ad-network beacons.
- Generate recommendations on a server that sees everything you typed.
- Sell, share, or merge your health data with other parties.
Almavivo
- Almavivo never receives them. Every answer stays in your browser.
- No account. No login. No profile.
- Zero third-party scripts. Enforced by a strict browser policy.
- The recommendation engine runs on your device. Nowhere else.
- We have nothing to sell, because we don't have it.
How Almavivo works
Not AI. A deterministic, rules-based engine. Auditable, line by line.
Almavivo is a transparent set of rules, the kind a clinician or pharmacist could read, argue with, and verify, running on your device. No language model writes your plan. Nothing you type is sent to OpenAI, Anthropic, Google, or any other model. Give the same answers twice and you get the same plan twice. That’s a property of rules. It is not a property of AI.
Deterministic
Same inputs produce the same outputs, every time. No randomness, no temperature, no “creative” phrasing. The engine is a pure function over your answers.
Rules-based, not generated
Each supplement has a written rule: who it’s for, who it excludes, what evidence tier supports it, what dose, what interactions to flag. Nothing is invented at runtime.
Open source
The engine is published openly at github.com/almavivo/open-health-engine under Apache 2.0. Every question, every supplement rule, every exclusion, every safety guard, auditable line by line, with citations to NIH ODS, Cochrane, and PubMed-indexed human trials.
Runs on your device
The engine is JavaScript that ships to your browser and executes there. No server-side inference. No API call to a model provider. Your answers don’t leave the page.
No hallucinations, by construction
A rule can be wrong, and we’ll fix it when it is. But it can’t hallucinate a study, invent a dose, or fabricate a supplement that doesn’t exist. That failure mode isn’t available to a rules engine.
Safety guards are explicit
Pregnancy, anticoagulants, SSRIs, kidney disease, under-18, red-flag symptoms. Each is a written exclusion or clinician-review gate, not a probabilistic guess.
Your health is not data. It’s yours.
Your answers are not signals. They’re yours.
Your plan is not a profile. It’s yours.
More than a questionnaire
A focused set of private health tools.
The intake is the start. Almavivo also includes annual physical prep, lab values in context, medication review, a shift-work circadian plan, a supplement journal, family health history, and short standalone risk screeners for prediabetes, sleep apnea, and alcohol. Every tool runs on your device.
Visit prep
Annual physical prep
Questions, screenings, and urgent symptoms to raise at your next GP visit. USPSTF, NHS, ATA, ADA.
Open →Visit prep
Medication review

A wellbeing benefit your employees can actually trust.
Six tools built on one private intake: supplement plan, lab values in context, annual physical prep, medication review, shift-work plan, household profiles. Every answer stays in the employee’s browser. Employers never receive individual reports. Open source under Apache 2.0, auditable by your DPO.
