I need a fully-featured custom plugin built from the ground up. The core requirement is straightforward: seamless integration with Open AI’s API so I can pass prompts from my site, receive responses in real time, and display or process those responses exactly where users need them. The brief in a nutshell • Platform: I marked “Plugin development” in the options, so I’m open to your recommendation on whether WordPress, Shopify, Magento, or even a framework-agnostic approach best serves the goal. If you have a strong case for one over the others, please lay it out. • Integration: Open AI is non-negotiable. Authentication, rate-limit handling, and a clean admin interface for setting keys and model parameters are essential. • Flexibility: I may extend the plugin later (for custom forms, e-commerce hooks, or SEO helpers), so a modular, well-documented codebase is important. What I’ll call “done” 1. A production-ready plugin package that installs without errors. 2. Admin settings page to manage Open AI API keys and model options. 3. Action or shortcode I can drop into any page to trigger and display AI output. 4. Clear README covering install, configuration, and hook/filter references. 5. Basic automated test or sample usage file showing the integration in action. If you can demonstrate prior Open AI or comparable API work, share a link or brief write-up when you reply.
