This works with the WooCommerce plugin. It will generate a description for your products using the OpenAI API.
Just input a title and save the product. The description will be generated and saved if the existing description is empty.
The plugin is free but you will need an OpenAI API key. You can get one for free from OpenAI however Open AI will charge you for the API usage beyond their free tier. You can see the pricing here.
