AI Text-to-Speech Learning Reader

Turn printed pages and PDFs into natural speech with word highlighting for language learners.

In plain English

A printed page or a PDF can be read aloud for someone learning a language. The phone app pulls the words off the page, speaks them in a natural voice, and highlights each word as it is said, across many languages. Learners pay for packs of pages or a monthly plan because hearing the words while they follow along helps the language stick. The AI does almost all of the reading, the speaking, and the payments inside the app. A person still checks how the voices sound, answers users, and helps the app show up when people search the phone store.
