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