Setting the standard for evidence in veterinary AI.
How much should you trust this paper?
Paste a PubMed ID, DOI, or PMCID and VECS grades a veterinary source A (High Confidence) to E (Preliminary) — reading the study design, checking the source for retraction and index verificationbefore scoring, and keeping study strength, where it was published, and applicability to your patient as three separate facts.

Most reliable: a PubMed ID/link, or the DOI itself — typed directly, or
already in a publisher link (Wiley, Springer, BMC, Frontiers, Taylor & Francis all put it right in
the URL). A plain publisher landing page (e.g. Elsevier/ScienceDirect,
MDPI) sometimes gets blocked by that site's own bot protection — we'll tell you exactly why if it
happens, no need to guess. Google Scholar's own pages can't be fetched
directly (Scholar blocks that) — copy the DOI from its "Cite" popup instead.
What is VECS?
VECS — the Veterinary Evidence Confidence Score — grades an individual clinical source (a paper, guideline, or label) on a five-level scale for how much a practitioner should trust it. Unlike human-medicine frameworks, it is built for veterinary medicine: it keeps three separate facts apart — how strong the study is, whether its source can be trusted, and how applicable it is to your patient's species — instead of collapsing them into one number. It grades clinical-decision confidence, not scientific importance: a landmark discovery and a small clinical study can share a grade.
A · High
B · Strong
C · Moderate
D · Limited
E · Prelim.

Grade a reference list
Paste up to 15 PubMed IDs / DOIs / PMCIDs (one per line) — grade a guideline's citations, or the sources behind an AI answer, in one pass. Also available as an API: POST /vecs/batch.
VECS grades each source on evidence design, execution quality, source verifiability, species applicability, and recency. The scoring methodology and weights are proprietary and withheld pending publication of our calibration data.
VECS grades the strength of a source — it is a research aid, not medical advice, and does not replace a clinician's judgment or a full reading of the paper. Always confirm dosing, thresholds, and species rules against the primary source.
