Generate professional brand logos — wordmark, icon, combination mark, monogram, emblem, or abstract mark — with structured generation prompts (logo type, style, color, detail level). Supports reference-inspired original marks and iterative refinement on an approved logo. Use when the deliverable is a single logo or logo direction, not a full visual system. Do not use for multi-asset brand identity packages with VI guidelines, packaging systems, or launch kits. Do not use for mascot or character IP design. Do not use for product-selling ads or marketplace listing visuals.
