MultiplAI is an API that takes in a base ad and outputs customized ads using various AI tools. The end goal is to generate more user engagement and a higher conversion rate. We use ChatGPT and Dall-E to convert the initial text and picture provided to us and customize it to one particular customer group, or even one particular customer, based on the data that is available about them. With increasing AI capabilities and more data being gathered for each individual user, big platforms and search engines will be able to not only cater the ads they show to a group of people, but literally personalize them for each individual user.
