My team and I are developing a digital (iOS) app that lets users send customizable digital cards. Users can choose from various card templates, enter their own text, and make edits to the card as they like. We also have a feature where users can provide a short message, like “happy birthday mom,” and receive an expanded version of the text, such as “happy birthday to my special mother! I love you and hope you have an amazing day.”

Currently, I’m conducting research to figure out how to accomplish this and planning to create a model using Natural Language Processing (NLP) and CoreML. However, I’ve encountered an issue in finding a suitable dataset for this particular task. As a result, I’m interested in building an accurate dataset specifically tailored to this purpose. However, I’m unsure where I can obtain the necessary data or if there are alternative data sources available for quick use.

If you have any insights or alternative methods to achieve this feature, please share them.
