Every word is timestamped, so listening and reading are the same activity. Text follows the narration word by word. Tap a word and the audio moves there. Pause, read ahead with your eyes, then pick up from where you actually got to.
BiblioSync aligns the narration to the text down to the word. Once that map exists, the features you'd expect from a reader and the features you'd expect from a player stop being separate things.
To know what is impenetrable to us really exists, manifesting itself as the highest wisdom and the most radiant beauty, which our dull faculties can comprehend only in their most primitive forms —
Everything a good audiobook app does — and a handful of things only a word-aligned one can.
The spoken word is lit; the rest recede but stay readable. Contrast alone carries the eye — no highlighter bar.
Find any phrase across the whole book and send the audio straight to it.
Save the exact word, not a rough time. Share it as clean text with a tap.
Holds a constant words-per-minute across narrators, so a slow reader and a fast one feel the same.
Chapter breaks are detected in what's actually read aloud, not guessed from file names.
Been away for a while? Get a short "previously" from the last stretch you heard. Heuristic, not magic.
Turn a passage into a shareable video — kinetic text, motion backgrounds, sound beds, a clean end card.
Attach an EPUB and it's aligned to the audio — publisher-perfect text, with figures kept in place.
Browse public-domain audiobooks from LibriVox, fetch them straight into your library, transcribe on your own machine.
Select any lines and export a vertical video where each word arrives as it's spoken. Every clip ends on the same quiet card.
The clip's words light up in time with the audio because it's the same timestamped transcript driving the player. No manual keyframing — pick the passage and it's already in sync.
Choose a text layout and a background, drop in a sound bed, and the end card carries the cover, title, and your rating. The mark is a signature in the corner, not an ad.
The alignment runs on a small companion app on your own computer — nothing is uploaded to a service. Set it up once and forget it.
Import an audiobook — or pull a free one from Discover. Add an EPUB too, if you have one, the same way.
Your computer runs the transcription and lines the words up with the audio, then sends a word-by-word transcript back.
The book lands in your library synced. Tap words, read ahead, search, bookmark, and make clips.
BiblioSync isn't a subscription and isn't a cloud locker. The transcription runs on your own PC; the library lives on your own phone. There's no account to make and nothing to upload.
One word is lit; the rest wait. Everything in BiblioSync is a variation on that single idea.
