What is Gutenberg Hub?

Gutenberg Hub is a WordPress plugin that adds AI writing capabilities directly into the Gutenberg block editor. It uses ChatGPT to help with content creation, rewriting, grammar correction, tone adjustment, and translation. The plugin works with your own OpenAI API key, so you control costs and have access to unlimited generation. It's designed for WordPress site owners, bloggers, and content teams who want to speed up their writing workflow without leaving the WordPress dashboard. The plugin offers real-time content streaming and preset configurations to make repetitive tasks faster.
