Rakuten Kobo Inc., a subsidiary of the Japanese e-commerce giant Rakuten, specializes in digital media and communication tools that bridge reading and social connectivity. Its compact portfolio centers on two consumer-facing applications: Kobo Desktop, a storefront-cum-reader for purchasing, organizing and enjoying eBooks across Windows PCs, and Viber, a cross-platform VoIP and messaging client that encrypts voice calls, video chats and SMS-style conversations for personal and small-business use. Together these offerings serve the dual modern needs of portable library access and low-cost global communication. Kobo Desktop supports EPUB, PDF and the proprietary KEPUB format, integrates with Rakuten’s online bookstore of over six million titles, synchronizes bookmarks, notes and reading progress to mobile devices, and provides adjustable typography, night-mode and built-in dictionary tools that appeal to casual readers, students and book-club participants who want a distraction-free study environment. Viber, meanwhile, targets travelers, expatriates and distributed teams that require HD voice, instant file sharing, community channels and end-to-end encryption without carrier charges; it complements email and conferencing suites by supplying quick peer-to-peer outreach and group administration on the same desktop where documents are edited. Both applications follow a freemium model, monetizing respectively through eBook sales and sticker-market revenue while keeping core functionality gratis. The publisher’s software is available for free on get.nero.com, with downloads delivered through trusted Windows package sources such as winget, always installing the latest versions and allowing batch installation of multiple applications.
