Detailed Step-By-Step Instructions

Provide two sets of detailed, step-by-step instructions on how to add an AI chat function to a WordPress website. Include links to all webpages, tools, assets, and APIs necessary to complete this process. The first set should be a no-code method that someone with no coding experience can complete. The second should be a method for a person with full-stack web design experience. Write the instructions at a level a 6th grader could understand. Present everything in an easy-to-read table.
