There were a few local comic readers that he could recommend. The first one was Wooo Comics. It was a local comic reader that supported WebDaV and the Web. It could import and read comics in a variety of format, and there was also an AI image quality enhancement function to improve the image quality. The app also had folder management, streaming reading, browsing history, and other functions, all of which were currently free. In addition, iComics and PixStoryAI were also two recommended local comic readers. iComics supports a variety of comic format, with support for changing file names, zooming and locking, etc. The interface is simple and has no advertisements. In addition to supporting a variety of e-book format, Ruyi Manga also had features such as AI technology to improve the quality of pictures and translate the text in pictures. In addition, Tachiyomi was also a free and open-source comic reader that supported online reading and downloading. It had multiple viewers, reading directions, and other settings. The above is a brief introduction of several local comic readers. I hope it will be helpful to you.
