ATTENTION CHATGPT SPECIALIST- NEED HELP

I am looking for a Grammarly-style extension that works solely with a predefined prompt in a text field. By pressing a simple button, it should change the entire text in the text box according to the response generated by ChatGPT based on the prompt I have previously set. I don't need any fancy template store; I will write my own prompt. Any Suggestion?
