Volume: Books Read Aloud

Import your own books and articles, read comfortably, and listen with a natural on-device voice that highlights along — fully offline, no account, no tracking.

Volume turns everything you read into one private, offline library — and reads it aloud with a natural neural voice, generated entirely on your device.

IMPORT ANYTHING Bring your own EPUB, Markdown, plain-text, and RTF files, or save web articles from the share sheet as clean offline publications. Everything lands in one searchable library, whatever its source.

READ COMFORTABLY A reflowable reader with themes, adjustable typography, highlights, and annotations that survive font changes. Instant resume, chapter navigation, footnotes in place — fully offline.

LISTEN WITH READ-ALONG Tap play and your book is read aloud by an on-device neural voice, with the current passage highlighted as it is spoken. Narration follows chapter jumps, keeps your place, works like an audiobook from the lock screen — and is kept, so it never re-generates on the next listen. Export a narrated edition as a standard audio-synchronized EPUB you own forever.

PRIVATE BY CONSTRUCTION No account. No ads. No tracking. No telemetry. Your books and your reading never leave your device — narration is generated locally, and everything works in airplane mode.

The User Guide is pre-loaded, so you can hear read-along the moment the app opens — and it doubles as a seven-chapter tour of importing, reading, and listening. Narration voices are synthesized speech (Kyutai pocket-tts, CC-BY voices); quality of pronunciation can vary on unusual words and names.
