What this does not cover.

1. Federal law outside the sources listed on the Sources page. Medicaid and CHIP managed care marketing is covered only through 42 CFR 438.104, 438.10 and 457.1224. Medicare is covered through the Part C and Part D marketing sections (42 CFR 422.2260 to 422.2267, 422.2272, 422.2274 and the Part D parallels in part) and the CMS marketing guidelines, not Medicare coverage, billing or enrollment rules. Medigap marketing (state law and NAIC model rules), Stark (42 CFR 411.350 to 411.357 is stored but has no rules), FDA and CMS overlaps, Federal Register preambles, and OIG advisory opinions other than the 25 stored are not covered. HHS pages and DOJ press releases were read from Internet Archive copies and should be checked against the live pages. OIG and DOJ materials describe allegations and settlements, not findings.
2. State law outside the states listed on the Sources page. States with rules are Alabama, Arizona, California, Colorado, Connecticut, Florida, Georgia, Hawaii, Illinois, Indiana, Kentucky, Louisiana, Maryland, Massachusetts, Michigan, Minnesota, Missouri, Nevada, New Jersey, New Mexico, New York, North Carolina, Ohio, Oklahoma, Oregon, Pennsylvania, South Carolina, Tennessee, Texas, Utah, Virginia, Washington and Wisconsin. For each, only the health-care advertising, referral-payment, professional-conduct advertising and consumer-protection provisions in the stored text are covered, plus consumer health data rules for Connecticut, Nevada and Washington. Connecticut, Nevada, Massachusetts, North Carolina and Virginia have only a few rules. Some state text is older than the current law (Georgia statutes 2019, Oklahoma 2019, Alabama 2023, Tennessee advertising rule 2009, New Jersey statutes from a 2019-2022 courtesy copy); the New Jersey Board of Medical Examiners advertising rule (N.J.A.C. 13:35-6.10) and the Tennessee and Oklahoma board and fee-splitting sections are not stored. Most of these provisions apply to licensed practitioners, and the checker cannot tell who is advertising.
3. Local IRB or institutional policy, unless your team adds it as a custom policy.
4. Ad platform policies beyond the pages listed on the Sources page (Google Ads and YouTube, Meta, TikTok, Snap, Pinterest, LinkedIn, X, Reddit, Microsoft Advertising, Amazon Ads, Spotify, Taboola, Outbrain, Nextdoor, Apple Ads, Yahoo). Each is an excerpt, some from Internet Archive copies that can be months old, and policy changes often. Quora has no rules because its policy could not be read. Platform rules are about approval and account risk, not law, and country and market tables are mostly not stored.
5. Images, video, audio, landing-page layout, and anything that is not the text you pasted.
6. Whether a claim is true. The tool checks wording against rules, not evidence.

• The rules miss claims by implication. In our test the rules alone blocked 56 percent of real warning-letter claims, at rule-set 0.6.0. The model read and the AI second read exist for that reason.
• The rules also over-fire on accurate statements, which is why you can override a finding with a written reason.
• Counsel review of the rule-set is pending. Laws and guidance change, so rules can be out of date or wrong.
• Precision on real customer copy has not been measured.

The numbers behind these statements are on the research page.
