GPT AI Power is a free WordPress plugin that connects directly to OpenAI using your own API key. Where AI Engine supports multiple AI providers and emphasises the chatbot and editor experience, GPT AI Power focuses specifically on content generation workflows – particularly bulk content generation for WooCommerce product descriptions and the ability to generate content from custom templates at scale.
Why GPT AI Power Is Worth Knowing About
Most AI WordPress plugins are built around the post editor experience – you are editing a single post and want AI assistance. GPT AI Power has a batch content generation interface that lets you queue up multiple content generation tasks and run them together. For a WooCommerce store with 200 products that need SEO-optimised descriptions, batch generation is a fundamentally different workflow than generating one at a time in the post editor.
The plugin is free on WordPress.org with a Pro version ($9.99/month) adding image generation, advanced chatbot features, and additional templates. The free version covers the core content generation functionality.
Step 1: Configure Your OpenAI API Key
Go to GPT AI Power -> Settings -> General. Enter your OpenAI API key. GPT AI Power only supports OpenAI – if you want Anthropic or Google models, AI Engine is the better choice. After entering the key, select your default model. For content generation: GPT-4o mini balances quality and cost. For higher-quality output: GPT-4o costs more but produces noticeably better long-form content. Configure the temperature (creativity level, 0-2 scale): 0.7 is a practical starting point that produces varied but controlled output.

Step 2: Content Generation from Templates
Go to GPT AI Power -> Content Writer. The content writer has pre-built templates for common content types: blog posts, product descriptions, social media posts, emails, and meta descriptions. Select a template, fill in the variables (topic, keywords, tone, length), and generate. The output appears in an editable text area where you can refine before inserting into your editor or scheduling as a draft post.
For blog posts, GPT AI Power generates in sections: first the outline, then each section, then the conclusion. This section-by-section approach produces more coherent long-form content than generating the full post at once, because each section request has a clearer scope.
Step 3: WooCommerce Bulk Product Descriptions
This is GPT AI Power’s strongest feature relative to other AI WordPress plugins. Go to GPT AI Power -> WooCommerce -> Bulk Product Writer. Select the products to process (all, by category, or individually), configure the description template (what to include: features, benefits, SEO keywords, tone), and run the batch. GPT AI Power generates descriptions for each product using the product title and existing attributes as context and saves them as the product’s short or long description.
Before running a bulk generation, test on 5-10 products and review the output quality. If the template produces poor results, adjust the instructions before processing hundreds of products. Bulk AI generation is fast to run and slow to manually fix if the output is consistently wrong.
Step 4: The Chatbot
GPT AI Power includes a customisable chatbot widget powered by OpenAI. Go to GPT AI Power -> ChatBot. Configure the system prompt (what the bot knows and does), select the model, and add to your site via shortcode or widget. The chatbot can be trained on your content by providing your site’s FAQ page URL or pasting specific information into the training field – this context is included with each conversation so the bot can reference it when answering questions.
