The "ChatGPTService" application we developed is an integrated solution for OutSystems, designed to analyze the sentiment of user-provided text. This application utilizes the OpenAI API, specifically the GPT-3.5-turbo model, to process the text and infer the expressed sentiment.

Functionality:

• Users provide an OpenAI API key and the text for analysis.
• The application, via the "ChatGPTRequest" component, sends a request to the OpenAI API.
• The request includes a pre-defined message instructing the AI to focus on sentiment analysis of the provided text.
• The response from OpenAI is processed by the "ChatGPTService" component, which determines if the sentiment is positive, negative, or neutral.
• The application returns the sentiment analysis result and the content of the response to the user in OutSystems.
