Can AI plan my kid's Halloween party?
Yes. Give it the guest count, ages, budget and anything to avoid, and it returns a menu, games, a timeline and a priced shopping list you can use this week.
01Why bot
- Party planning is a checklist problem: food, games, timing, shopping. AI is good at turning a few facts into that list.
- It keeps the plan inside the budget you give it and the ages you name.
- It does not know your local store prices or your guests' allergies unless you say so, so you check those.
