How to read the results
Useful for a fast wording check, limited by the public record.
This free tool is intentionally narrow. It does not scan your site, judge the full context of a page, read substantiation files, or compare every possible FDA and FTC rule. It only checks whether your pasted wording shares tokens with phrases extracted from FDA warning letters that are already in the ClaimSweep database.
That narrowness is the point. If a similar phrase appears in a warning letter, you get a source link and enough context to decide whether the wording deserves review before it goes live. If no match appears, treat that as a database result, not a green light. The public warning-letter set is growing, the ingest job is still backfilling older letters, and a phrase can raise concerns even when it has not appeared verbatim in a published letter.
For a broader sweep, use the store-scan CTA. The paid scanner is planned to read your product pages, Amazon listings, ads, and social copy together, then keep watching new pages as your team publishes them. This lookup is the free front door: fast, source-grounded, and designed to show exactly what public FDA letters have said about similar language.

What should I paste?
Paste the exact claim, headline, bullet, ad line, or label wording you are considering. Short phrases work best because the search matches meaningful tokens and ranks shorter cited phrases first.
Why do some matches say partial?
When every token is not found together, the tool can show a partial match if enough tokens appear in a cited phrase. That helps early users discover nearby warning-letter language while the dataset is still growing.
What happens after I click the source link?
The link opens the FDA warning letter on fda.gov. Read the surrounding letter language, the company name, the date, and whether a closeout letter is on file before drawing business conclusions.
