Spine - Chapter Reader

Copy a clean chapter into the language model you already use, or listen with voices installed on your device. Spine never uploads your books.

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. One tap copies the current chapter as clean plain text, with the book, author, and chapter title included. Select a passage when you only need a smaller excerpt.

Prefer to listen? 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. It does not decrypt DRM-protected books.
