PosterCraft: Revolutionizing High-Quality Aesthetic Poster Generation in a Unified Framework

The Design Revolution You’ve Been Waiting For

Have you ever struggled to create professional posters? Faced with fuzzy text rendering in AI-generated designs? Watched artistic elements clash with backgrounds? PosterCraft solves these challenges through its groundbreaking unified framework. Developed collaboratively by researchers from The Hong Kong University of Science and Technology, Meituan, Xiamen University, and National University of Singapore, this innovative system achieves unprecedented precision in text rendering and aesthetic harmony.

Performance breakthrough: PosterCraft achieves 0.787 text recall – outperforming SD3.5 (0.565) and nearly matching Gemini2.0 (0.798) in independent benchmarks.

What Makes PosterCraft Special?

PosterCraft is the first unified framework dedicated to high-quality aesthetic poster generation. It combines four core capabilities in a single architecture:

1. Precision text rendering – Crystal-clear readable text elements
2. Seamless artistic integration – Natural blending of abstract elements
3. Dynamic layout composition – Professional-grade visual arrangements
4. Style consistency – Unified aesthetic across all components
