What it solves

This project provides a framework and automated workflow for creating high-impact, minimalist marketing copy and posters. It adapts a specific "double-layer semantics" methodology—originally used by Durex between 2011 and 2017—to any product category (such as AI courses, finance, or fitness) to create a "moment of realization" for the reader.

How it works

The tool is implemented as a Claude Code / Claude.ai Skill. It follows a strict interactive process to avoid overwhelming the user with questions:

1. Assumption-based Start: Instead of asking for every detail, it makes explicit assumptions about the target audience and platform to move quickly to a concrete proposal.
2. Diverse Options: It generates 3–5 distinct conceptual directions based on eight specific copywriting formulas (e.g., homophonic replacement, double entendres, and "reverse restraint").
3. Layered Production: To avoid AI-generated text errors in images, it separates the process into two stages: an AI image model generates a clean, text-free still-life object/background, and a code-based layout engine (Canvas or HTML/CSS) overlays the precise typography.
4. Visual System: It applies a rigorous set of rules for color palettes, typography, and layout (e.g., maintaining at least 50% white space and specific keyword scaling).

Who it’s for

Marketers, social media managers, and content creators who want to produce professional, minimalist, and witty marketing assets without needing a deep background in advertising agency methodology.

Highlights

• Double-Layer Semantics: A mechanism where the surface text refers to a trending topic or daily scene, while the underlying meaning refers to the product value.
• Code-Driven Typography: Uses @napi-rs/canvas or Playwright to ensure Chinese characters are rendered perfectly and are easily editable.
• Formulaic Approach: Includes 8 proven copywriting formulas to ensure variety and creativity.
• Safety Boundaries: Built-in constraints to prevent the物化 of women, inappropriate sexual hints, or the use of tragedy for marketing.
• Commercial Font Guidance: Provides a curated list of free commercial-use fonts to avoid legal risks.
