MicroBoard.io is an online drawing whiteboard that allows remote collaboration. While it is designed for managers, it is suitable for anyone. Although there are many similar boards on the market, we have paid special attention to making it convenient for managers to use. We will discuss these details later. In 2020, due to the pandemic, people began to communicate through video conferencing en masse. Previously, colleagues could discuss things in person in the office, but now many people are doing this through video conferencing. Some find this inconvenient because they have to explain things in detail. Our board allows users to draw together, create diagrams, and make plans so that everything is visual. Even if two people are drawing, dozens of people can watch. These types of boards are familiar to students because they have switched to online learning, and teachers use similar online boards instead of traditional chalkboards. Our board is versatile; students and others can use it, but it is especially convenient for company managers.
