Risk: High

Starting an AI website and app UI design service from scratch can be risky for someone who can't afford to lose money. There is a potential to lose both time and money, especially if the business fails to attract clients. Beginners might spend money on marketing efforts or tools without seeing returns. Startup costs for software, tools, and marketing can be significant and may not pay off if the business doesn't take off. Online discussions mention instances of people failing or losing money due to lack of demand or competition. I'd rate the risk a 1 out of 3 because there is a high chance of losing money, time, and confidence if the business doesn't succeed.
