Startup cost: $500 - $3k

Setup costs range from $500 to $3,000 depending on the level of investment. At a minimum, someone starting an AI-Powered Knowledge Base Builder side hustle would need to budget for essentials like a domain name ($10-$20/year), website hosting ($100-$200/year), and basic software tools for content creation and management ($200-$300/year). Optional expenses could include paid advertising on social media platforms ($50-$100/month) to drive initial traffic. Hidden or recurring fees may include software subscription renewals and occasional maintenance costs. Those looking to do it right may invest in professional website design services, premium software licenses, and more extensive marketing campaigns, pushing the costs towards the higher end of the range. I would advise a friend to budget around $1,500 to $2,000 to start this side hustle seriously.
