Your AI UGC creator looks different in every video. Here’s the fix. I shipped 300+ creatives with Claude + GPT-Image-2.5 + Seedance 2.5, and the biggest problem was never quality. It was consistency. Same prompt. Same reference. A different person every time: - The jawline shifts - The hair falls differently - The freckles move 2mm Small stuff, but across scenes and ads, people notice. The fix is a system, not a better prompt. Here’s what’s inside: ✓ Identity sheet - Locks one face across every render - Works this week and next month ✓ 6 copy-paste prompts - Angle minerIdentity sheet - Hook script - Product-in-hand render - Variation matrix - Reject pass ✓ Casting table - 6 creator archetypes - Matched to 6 DTC verticals ✓ Master render prompt - Bracket-filled for skincare, supplements, apparel, home, food amp; bev, and accessories ✓ 6-check reject pass - Kills a bad take before it reaches your ad account ✓ Approval table - One row, you fill it in, done All you need is one product photo. I packaged the whole process into one guide. Get free access below. 👇
