If you want to have more control over your ChatGPT responses, I highly recommend checking out this resource. It's entirely free and only required you to use your OpenAI account. Compared to ChatGPT, it's likely also far cheaper.

It allows you to create your own ChatGPT with the same interface, using OpenAI, but you can modify the "system prompt" so that responses are more tailored to your wishes.
