Koodo Reader is a cross-platform ebook manager and reader that supports Windows, macOS, Linux, Android, iOS, and web browsers.
The tool addresses the need for a unified reading experience across devices while preserving reading progress, notes, and library organization. It handles a broad range of formats including EPUB, PDF, MOBI, AZW3, plain text, FictionBook, comic book archives, Markdown, DOCX, and HTML. The core approach centers on local-first storage with optional cloud synchronization through multiple providers—OneDrive, Google Drive, Dropbox, iCloud, MEGA, pCloud, and others—plus direct protocol support for FTP, SFTP, WebDAV, and SMB. The tool includes built-in features for annotation, text-to-speech, dictionary lookup, OCR, and integration with note-taking systems like Obsidian, Notion, and Readwise.
Koodo Reader suits readers who want format flexibility and cross-device continuity without vendor lock-in. It works well for those managing large personal libraries, using multiple reading devices, or requiring privacy-conscious synchronization. The privacy-first design explicitly avoids tracking and proactive data uploads. The plugin ecosystem and support for custom AI models appeal to users wanting extensibility beyond the built-in feature set.
The project maintains steady engagement with its user base, with nearly all open issues originating from adopters rather than the core team, indicating substantial real-world usage. Maintainers typically respond to new issues and pull requests within a few days. Activity in the issue tracker centers on feature requests, bug reports, and user questions, reflecting ongoing development driven by community feedback.
