Your place stays aligned whether you read, listen, or scan a page.
Two ways in
Bring what you have
The demo above is the result. Here is how you get there from your own files.
Sync
EPUB + audiobook you already own
Sync into one ebook with the real narration laid over the text — a read-along that keeps your place.
Narrate
EPUB only
Tribooks generates the audio so you get the same read-along — text highlights with the voice.
Shop
Free classics, already synced
Public-domain titles with a real ebook and LibriVox audiobook paired into one read-along. Add any to your library — no payment step.
Pricing
Free to start, upgrade when your library grows
Every plan includes reading and listening. Book Credits pay for syncing your own files or generating narration.
- 1 bonus Book Credit when you subscribe
- 3 new Book Credits every month
- Up to 30 books in your library
One Book Credit syncs your matching audiobook into a read-along Tribook, or generates Studio AI narration. Immersive Cast (two credits) and Premium Cast (three) are fuller AI narration options. Exceptionally long books always show the exact price first.

Yes. Upload an EPUB and Tribooks can generate AI narration — Studio (one voice), Immersive Cast, or Premium Cast — so you get a listen-along audiobook experience with highlighted text. No separate audiobook file required. If you already have matching audio, sync that instead of generating narration.
Upload an EPUB with matching audio to sync, upload an EPUB alone to narrate, or add a pre-synced classic from the shop. Organize with tags, ratings, and series.
Yes. Download books for offline reading and listening. Progress syncs when you are back online.
