The Challenge

Clients need many different features on their Custom WordPress websites and some features may require a developer’s skill. But ChatGPT’s generative coding abilities are coming to the rescue!

The Process

Using the Pro Version of ChatGPT 4o in April 2025 – I prompted: “Can you please build a custom WordPress plugin for a Mortgage Calculator with the basic fields.”

ChatGPT responded back with the instructions on how to install it, the full PHP & CSS code, and even the shortcode needed to render this calculator.

Generative AI Podcast Audio from Deck Presentation

Multimedia Communication

This project addresses the challenge of creating accessible, multimodal content that engages diverse learning styles without requiring extensive manual effort. By utilizing NotebookLM, I transformed a static PDF presentation deck into an interactive podcast audio file, allowing learners to engage with the material through auditory content. This solution enhances accessibility and saves time, making it easier to deliver information in multiple formats for different audience needs.
