Group chats are good at starting ideas and bad at finishing them. A sidequest prompt makes the next step obvious: what to do, when to do it, and what proof to bring back.
Prompts you can send today
Try everyone submit one dinner option by 4, first person to spot a yellow door wins, take a photo of the best view on your walk, or bring proof of the cheapest good snack you can find.
Use constraints
Constraints make prompts easier to answer. Add a time, place, budget, color, theme, or proof type so the group knows exactly how to play.
