We are developing next generation design tool “STUDIO” for digital service. In the current service production flow, the design and development flow is completely divided. This separation causes range of problems. One of the big causes is designing with an illustrator tool. As a solution, we have created a code-base design tool. What makes STUDIO unique is that it has a distinct feature that enables a designed project to become a real product. Although there is alternative code-base tool, such as “Webflow,” it is complex when compared with a design tool. With STUDIO’s patented original layout method, we have succeeded in simplifying it similarly to a design tool. Also, in STUDIO it is possible to design with a real data.
