Claim Substantiation Checker for Regulatory Marketing Audits
This Connector cuts that cycle down to seconds. You feed your copy to your AI client, and it instantly flags every "best," "fastest," or "guaranteed" that needs a footnote. You get a list of corrections instead of a rejection letter.
What Vinkius changes
You get a ready-to-fix audit of your marketing copy instead of a generic "fix this" from legal.
Use it from Claude, ChatGPT, Cursor or another AI client you already have.
