I understand your concern. The copycat problem is real.
But if you come from a technical background and this is your first time building a product, you'll soon learn that it is so damn hard to get users, especially *paying* ones.
I was there. I built something, shared it, prayed people would notice. The truth is most of the time your product fails. Better explore the problem you are trying to solve first, share your idea if necessary, and collect feedback. You'll have a much clearer picture of what you need to do from there.
