About

VoiceStudyFlow

Features

VoiceStudyFlow turns your PDF books into a calm, focused study experience. Add a file, open it, and listen in a clear human voice — in English or Arabic — instead of tiring robotic voices. A moving magnifier follows along so you never lose your line. What you can do: • Read & listen — upload any PDF and hear it in a natural voice, with speed control and section navigation. • Smart study plan — set your daily minutes and the app spreads the book's pages across days automatically, with rest days. • Lens reading — a large moving magnifier focuses every word as you read; turn your device sideways for a bigger view. • Pronunciation & translation — accurate pronunciation and instant translation. • AI tools — one tap to summarize a page, generate questions, flashcards, a mind map, or a presentation. • Focus & tracking — a Pomodoro timer, a daily streak, and a focus mode that cuts distractions. • Organized library — folders, archive, and a study syllabus with quizzes and audio summaries. Your books and progress are kept privately in your account and fully separated from others. You are responsible for the content you upload. Designed and developed by Nahla · Made in Riyadh.
