Safer: cite the study you actually find, with its year and sample.

About this skill

About AI draft fact-checker

AI drafts sound confident even when names, numbers, quotes or citations are wrong, and errors get published. This skill lists every checkable claim in your draft — numbers, dates, names, quotes, citations and legal or medical statements — and marks each as supported, unsupported or contradicted by the sources you paste. It rates the risk if a claim is wrong, explains how to verify each high-risk one and suggests safer wording. It never verifies a claim from memory, and treats any citation it can't see as unverified. To use it, paste the skill into your assistant and send a draft written with (or by) AI, and the sources it was based on if you have them.
