iSilo

iSilo is a document reader and organiser for macOS that specialises in viewing, managing and storing offline copies of web content, ebooks, technical manuals, and reference materials. Users can sync content from web sources, organise documents into libraries, and read them without needing an internet connection. The app includes bookmarking, searching across documents and note-taking features. It was particularly popular among professionals who needed reliable offline access to documentation and ebook collections.</description> <parameter name="recommendation">We could not find current information about iSilo's Apple Silicon support or active development status in available sources. To determine whether you should plan an alternative before macOS 28 ships in September 2028, contact the developer (DC2 Consulting) directly and ask whether a native Apple Silicon build exists or is planned. If the developer confirms no native version is coming, you will need to migrate your document library to another app before Rosetta 2 is removed in September 2028, since the current Intel-only build will stop launching on that release. For offline document reading and management with confirmed Apple Silicon native support, consider Calibre (free, open-source, primarily for ebook management and conversion), NotePlan (note-taking and markdown), or Apple Books (for ebook content). The specific choice depends on your document types and workflow.</recommendation> <parameter name="recommendation_name">iSilo
