This is FlowPaper
FlowPaper is a product of Devaldi Limited, a company in New Zealand. It was started under the name FlexPaper, as an innovative solution for digital publishing in 2010, specifically aimed at creating seamless and interactive document viewers. Over time, it evolved to become a cornerstone in the digital flipbook and document viewer industry, eventually transforming into what is now known as FlowPaper. This transition marked a shift from a static document viewer to a more dynamic and feature-rich platform for creating interactive content.
