What it does
Give Claude your marketing content along with the data or sources you have to support it. Claude pulls out every checkable claim, such as statistics or awards, and matches each one against your evidence, flagging anything unverified or contradicted. You get a clear breakdown of which claims are safe to publish and which need more proof.
Who it’s for
A good fit for marketers, founders and anyone promoting a business and people who review contracts and legal documents.
Do you need to code?
No. You can use this without writing or editing any code.
How to install
Add it as a skill, or as part of its plugin. This skill also ships inside a plugin, so you can upload just this skill to Claude, or install the whole plugin it comes in. See the step-by-step guide.
Safety note
Runs bundled Python scripts on your computer; reads evidence files you provide; gives legal/compliance info - not professional advice.
As with any add-on, only install skills from sources you trust, and read what it does first.
