General health and wellness research synthesis covering core wellness, nutrition, lifestyle science, and emerging health mechanisms.
We evaluated Knitify Health Basic against four Gemini configurations on 30 health/wellness queries. Knitify achieves 97-99% citation fidelity compared to 26-80% for Gemini. 89% of Knitify Premium citations are from 2025-2026 — the highest recency rate across all 6 Knitify domains.
Citation fidelity measures whether each cited reference is a real paper that exists in PubMed and is relevant to the claim it supports. This is verified independently — not by the AI judge.
How citation fidelity is measured: Each reference cited by Gemini is resolved via CrossRef (DOIs) and PubMed (PMIDs). An independent AI verifier compares the resolved paper against what was claimed. If the DOI returns 404 or the paper is on a different topic, the citation is marked as hallucinated.
