Volume: Books Read Aloud

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 — filed straight into a collection if you like. Everything lands in one searchable library, whatever its source.

READ COMFORTABLY
A reflowable reader with themes, adjustable typography, instant resume, chapter navigation, and footnotes in place — fully offline.

KEEP WHAT MATTERS
Highlight passages and add notes that survive font changes. See them gathered for one book or across your whole library, and tag them by topic to find them again.

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. Figures, tables, code, and equations are announced instead of silently skipped, and short pauses mark headings, quotations, and section breaks. Narration follows chapter jumps, keeps your place, works like an audiobook from the lock screen — and by default is kept, so going back or listening again is instant.

IN THE CAR
With CarPlay, pick a recent book on your car's screen and narration picks up where you left off, with chapters a tap away.

TAKE IT WITH YOU
Export a narrated book as an M4B audiobook with chapter markers that plays in any audiobook app, or export the original file you imported. Books you finish are marked automatically, and Clean Up clears out what you're done with in one step.

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.
