Audeus
Audeus is an immersive text-to-speech TTS reader. The official website emphasizes that it can read PDFs, Word Docs, GDocs, ebooks, web articles and custom texts, and supports Web Apps, iOS Apps, Android Apps and Chrome Extension. It helps students, researchers, law or medical learners turn long documents into audible content by synchronizing text highlighting, voice selection, automatically saving reading locations, and estimating listening duration. Audeus offers free trials and paid subscriptions for users who read a lot of material and want to listen and read it; it is not a summary tool and still requires users to understand the content themselves.
