Koodo Reader

Read and organize your e-book library with Koodo Reader, a free, open-source e-book reader designed for simplicity and comfort. Whether you collect classics, comics, or technical documents, this app brings your entire reading collection into one unified library with seamless access across all your devices.

Support virtually every format you own. Koodo Reader handles EPUB, PDF, MOBI, AZW, TXT, FB2, CBR, CBZ, CBT, MD, DOCX, HTML, and MHTML files. You can load traditional novels, graphic novels, scanned documents, and plain text files without format conversions or compatibility headaches. If it contains readable text, this reader opens it.

Pick up where you left off on any device. Because this app runs on Windows, Mac, Linux, Android, iOS, and in your web browser, you can start a chapter on your desktop and continue reading from the exact same page on your phone or tablet. Cloud synchronization keeps your library and reading progress in sync across platforms. Connect to OneDrive, Google Drive, Dropbox, MEGA, pCloud, Aliyun Drive, or Box—choose the service you already use.

Accelerate reading with AI-powered tools. Built-in AI translation helps you read books and documents in foreign languages by generating translations directly within the app. An AI summary tool distills long passages into key points, making it fast to review contracts, legal texts, or dense reference material without reading every word.

Free to start, with optional premium features. The core reader is completely free with no ads or limitations on basic use. A PRO account unlocks full access to AI features and priority cloud synchronization for keeping your library up to date across devices. A seven-day free trial lets you test the PRO experience before committing.

Koodo Reader combines clean design with powerful functionality—no clutter, no unnecessary complexity. Download the app to build a reading habit that works across your entire digital life.
