やることまとめくん — LINE グループのやることを LINE で完結

This is a LINE bot for families, circles, PTAs, small teams, and others whose daily communication is completed within LINE groups. Small tasks like "taking out the trash" and "collecting fees" tend to get lost in the conversation flow, leaving it unclear who should do them and they end up being neglected. However, the reality is that dedicated task management apps don't take hold because they require everyone to install them and develop the habit of using them.

That's where "Yaru Koto Matome-kun" comes in. Simply invite it to your group, and you can register tasks, assign responsibilities, set deadline reminders, and visualize a task list—all in your regular LINE chat room. It's a tool that lets small teams clearly manage their to-do items without having to learn a new app!
