How it works

Sourced answers in three steps

A transparent process you can follow and check.

Enter your question

Type a health goal, a symptom, or a supplement name in your own words. No clinical terminology required.

We search the literature

We retrieve relevant papers from a self-hosted corpus of 200M+ scientific publications, drawn from trusted sources.

Read a sourced summary

A plain-language summary: what the evidence supports, typical dosing where established, and the specific studies behind each point.

Retrieval, not generation

Retrieved and cited, not generated

General-purpose chatbots compose answers from training data and can produce citations or dosages that cannot be verified. NutreeGuide retrieves each answer from a self-hosted research corpus and cites the actual paper behind every claim.

Where answers come from

NutreeGuideRetrieved from a self-hosted corpus of 200M+ publications, with the source study cited for every claim.

General AI chatbotsComposed from training data, with sources reconstructed after the fact rather than retrieved.

Citation accuracy

NutreeGuideEvery cited paper is a real record in our corpus that you can open and read in full.

General AI chatbotsCan fabricate plausible-looking studies, authors, or dosages that do not exist.

Evidence grading

NutreeGuideEach conclusion carries a grade, from systematic reviews and trials down to early data.

General AI chatbotsTypically states conclusions without indicating how strong the underlying evidence is.

Coverage and recency

NutreeGuideSearches the live corpus on each query, so findings reflect the indexed literature.

General AI chatbotsLimited to a fixed training cutoff and unaware of research published since.

You can open and read every cited study yourself. NutreeGuide informs your decisions; it does not replace advice from a qualified clinician.

Evidence, made checkable

Why you can trust what you read

We do not tell you what to conclude. We show the evidence, cite its source, and state how strong it is.

Graded by strength of evidence

Each recommendation carries an explicit grade, from systematic reviews and human trials down to early research, so you know how much weight to give it.

Linked to the source studies

Every claim points to the peer-reviewed paper it rests on. You can open the original research and check our work at any time.

Written in plain language

We translate dense findings into clear takeaways, without altering what the research actually reports.

From sources clinicians trust

Evidence is drawn from PubMed, the NIH, Cochrane, ScienceDirect, and Nature, not from blogs or product marketing.
