Selling my code + IP does also prevent me from launch another similar product?

I've a news website operating by AI, it has no visitors and I don't use that anymore, but someone messaged me to buy it (the code and IP, including name and domain) for a pretty cheap price at 2k usd. Since I'm not improving it anymore, I'm thinking about selling it, but I am in doubt if it would prevent me from in the future launching another similar product, like a website with a similar news AI generated section. I know that if the terms of the selling says that obviously I couldn't, but what if the selling terms don't say anything explicitly about it?
