Fred (Founder) served as lead AI engineer at an agent platform that went viral—then almost bankrupt. He learned painfully: offering free AI usage without limits creates dangerous liabilities.
AI@YourService was born to help developers avoid the nightmare of huge LLM bills, while still letting real users test freely. Fred built exactly the tool he wishes existed back then.
