Brand Voice Checker

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; your approved-claims register; an overview of what is set up for each brand (voice guide, target markets, registered claims and rules); and the results of site content audits you have run on the website, including the pages with the most claims to review and which claims are not yet approved.

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. Site audits are started, and paid for, on the website; in Claude they are read-only. A Brand Voice account is needed; brand voice tools need the brand's guide, which you create at brandvoice.thelostagency.com.
