Volume: Text to Speech Reader

Volume turns the books you own and the articles you find on the web into one private, offline library — and reads them aloud with a natural neural voice, generated entirely on your device.

SAVE ARTICLES FROM YOUR BROWSER
Found something worth reading? Tap Share in Safari or another app and save it to your library as an article — a clean, offline copy of the text, ready to read or listen to like any book. File it straight into a collection if you like.

IMPORT YOUR BOOKS
Bring your own EPUB, Markdown, plain-text, and RTF files. Books and articles land in one searchable library, whatever their 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 or article 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, your articles, and your reading never leave your device — narration is generated locally, and once something is saved, 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.
