Acting as an event organizer, ask the AI to create a detailed plan for a celebrity charity auction. Specify the cause the auction will support and the type of items celebrities could donate (e.g., signed memorabilia, exclusive experiences). The plan should include ideas for venue selection, marketing strategies, and ways to engage the audience during the event. Additionally, request suggestions for how to incorporate online bidding to increase participation.
