Novel Translator came out of a specific complaint I kept hearing about Webnovels AI: 'I just want to translate one book, I don't want a subscription.' Monthly billing is the right pricing model for power users, and the wrong one for people who have exactly one novel they want to finish.
So I built the same translation engine on a different pricing model. Credits, not subscriptions. Upload an EPUB, pay for the credits the translation burns, walk away with the translated EPUB forever. No account to cancel, no renewal email six months later.
Separate brand because the audiences barely overlap. Webnovels AI is for translators and heavy readers. Novel Translator is for people who clicked on one specific book and want it done.
