Description
Brand Voice Checker brings The Lost Agency's brand voice and claims-compliance checks into Claude. Paste a product description, an email or a social post and ask Claude to check it. Free with any Brand Voice account: a quick scan for risky claim wording (guarantees, superlatives, health, green and price claims), reading ease and stock AI phrasing; the claims rule catalogue; your credit balance; and your approved-claims register. With credits, at the same prices as the website: a full compliance check resolved for your target markets (UK, EU countries, US and more) with your approved claims and house rules applied; a brand voice score against your own voice guide; rewrites towards your brand's voice that flag any risky wording they introduce; and new drafts that use placeholders instead of inventing facts. Each paid check costs 1 credit (rewrites and drafts 1 credit per 2,000 characters), Claude asks before running one, and every result says what it cost. A check that fails is refunded. Each person connects their own account. Copy you send is processed and returned, not stored. A Brand Voice account is needed; brand voice tools need the brand's guide, which you create at brandvoice.thelostagency.com.
