Developer Gudong released Gudong Cover, an open-source web app that generates cover images for WeChat Official Accounts and Xiaohongshu. It removes the need for IDE tools or coding knowledge, letting non-technical users create consistent, AI-generated visuals by simply entering article content. The tool is free to use and hosted online.

The app uses Gemini 3 Flash for generation, producing HTML-formatted covers in under two seconds. It offers dual modes: a WeChat Mode with a 2.35:1 landscape ratio for technical content, and a Xiaohongshu Mode with a 3:4 portrait ratio for vibrant, emotional posts. Users can download high-resolution PNGs directly.

Gudong built this using Google AI Studio to solve a personal workflow bottleneck. The source code is available on GitHub, and the developer encourages custom API key integration. This tool streamlines content creation for writers focused on China's major social platforms, bridging the gap between AI capability and user-friendly design.
