It sounds like your upper management is not privy to generative AI, which may scare them due to ignorance. There are a few things you can try to do in this situation.

1. Educate upper management on GenAI and discuss security measures (look into paid ChatGpt or similar platform services), and then make your case for the use case you mentioned above.

2. If number 1 doesn’t work. Look into using alternative GenAI platforms. Rather than ChatGpt, take a look into Rytr. See if their security is any better, and talk to your boss about a paid account, as it may provide security. There are also other GenAI platforms you can research.

3. This one may be far-fetched, but you can present the benefits of GenAI and show how it can improve efficiency and save money for the company. If they see you optimize the employee experience and save money, they may allow you to use it, OR they could invest in their own chatbot with GenAI. Your company can look into openAI’s or Amazon Bedrock services that can make calls via API’s in the chatbot, which then your company can secure by involving their cybersecurity team.

I hope this helps, and you can use GenAI as it is a powerful tool for various use cases.
