I had a bunch of ebooks with no audiobook version available. So I built an iOS app that converts EPUB files into audiobooks using text-to-speech.

Two voice options: - Free on-device voices (processed locally, no server needed) - Natural cloud voices (one-time purchase per book, no subscription)

Cloud conversion runs chunk by chunk. You can start listening other chapters generate in the background. Once done, the audiobook lives on your device.

No account required. No subscription. You import your own EPUBs and either use device TTS for free or pay per book for the cloud voices.

Nothing stored on backend, neither books or audio files.

Both examples on your images - Call of the Wild, and Pride and Prejudice - have audiobooks available. Maybe better to showcase books that really don’t have audiobooks, if that’s the intended use case.

Thanks for making this available, I will give it a go this week. Unfortunately, previous attempts with these technologies have been quite disappointing, I really wanted my dad, who is now blind, to listen to the last book I wrote, but when I tested it out on the first chapter it really screwed up the nuances, so he is still waiting.

Nice , I use speechify for that, I’m listening to epub and able to read at the same time , summarize or quiz . I pay $139 yearly but it comes out cheaper than if I had paid $9 perbook .
