What problem does it solve? Marketing copy written without grounding in real customer research tends to be generic and untestable. This Skill walks you step by step from your existing Lean Canvas and Customer Journey Map to a homepage where every claim traces back to your maps, carries an evidence status, and includes a concrete test plan. ## Core Features & Use Cases - Map-grounded copy drafting: Drafts each homepage section (hero, problem, audience, plan, proof, price, FAQ) directly from your canvas boxes and journey rows, quoting customer words verbatim. - Five-field risk audit: Every section gets a claim, map trace, question, evidence status (know vs. not sure yet), stakes, and a cheapest-way-to-test check. - Annotated HTML artifact: Outputs a single self-contained HTML file with risk pins (product/customer/market), a side-panel inspector, a competitor swap strip, and a final check summarizing what's really yours and what to test first. - Use Case: A workshop participant with a completed Lean Canvas and journey map wants a homepage they can actually test — the Skill drafts each section from their maps, audits it live, and produces an annotated page showing which claims are proven and which are still hopes. ## Quick Start Ask the AI to build my marketing page from my Lean Canvas and Customer Journey Map using the grounded marketing artifact skill.
