Read a chapter. Copy it cleanly. Continue in the language model you already use. Spine is a focused EPUB reader for people who want to read alongside an LLM without putting AI inside the bookshelf.

Spine reads aloud with Apple voices installed on your iPhone, iPad, or Mac. Choose a voice and adjust its rate, pitch, and volume—without a voice account or a cloud reader. Your library stays private. Spine has no built-in model, requires no account, and does not upload book content. What you copy is yours to paste wherever you choose. Spine also includes: - EPUB 2 and EPUB 3 support - Chapter navigation and in-chapter search - Reading-position restoration - Bookmarks and inline notes - Adjustable type, size, and line spacing - Drag-and-drop and system document opening - Guardrails for unusually large or malformed files Spine reads DRM-free EPUB files.
