SubRead

Line an audiobook up with its ebook, sentence by sentence.

Drop in an audiobook and the ebook it was read from. You get back subtitles timed to the narration, with the wording taken from your own book — not from a machine's guess at what it heard. The work happens in this tab, on your computer.

Free in your browser, without limit.

The JavaScript version does not use any cloud credits.

Share on honjimaku

honjimaku.com is a free library of subtitles for Japanese audiobooks. Other learners can then read along with this book and do not have to make the subtitles again.

The key stays in this browser. The subtitles go from this tab to honjimaku.com and to nowhere else. They hold the words of the book: share them only if you may.

Credits for our server

Paid through Stripe; we never see your card. One credit converts one book on our server, with every output. Credits in a pack never expire, and a job that fails gives its credit back. A monthly plan renews each month until you cancel it with "Manage plan"; its books do not carry over to the next month. In this tab a conversion is always free. Paying also creates your account, under the email you give Stripe.
