House Beaver  is a tool that allows anyone to easily prevent and detect water leaks at home without the help of experts by visually showing users the sounds of water leaks and non-leaks based on information accumulated through machine learning technology. Water leaks in the home cause the waste of scarce essential resources, pollution of land and water, personal property damage, and disputes between neighbors. Contrary to common belief, this does not only occur from the upper house to the lower house. In multi-family houses, water can leak from unexpected places through gaps in the walls. However, the only way for ordinary people to find this is to rely on experts with expensive equipment. Experts use their personal experience to determine whether the sound is a leak or normal water sound from plumbing. House Beaver replaces this expert experience with an AI leak detector.
