How can you expect a robot to give you a good business plan that would be profitable? The mistake we make now is that we think Ai is capable of doing anything and we give it too much reliance. Ai can make our work easier and faster, no doubt about that but when it comes to making a business plan you need the input of humans, after all it's a human world and not an ai world. For you to make a good business plan you need more than just suggestions and that's the only thing that ai can give you, there are lots of things that you must put into consideration if you are going to come up with this. Chatgtp is a bad idea to do this.
