CastReader turns any text into something you can both hear and understand. Read Aloud — like a teacher pointing along Turn photos, web pages, PDFs, EPUBs, and plain text into natural speech with one tap. Every word highlights as it's read and the page auto-scrolls, so your eyes and ears stay focused together. Finish an article on your commute; follow each word while practicing listening. AI Explain — not just read, but understood CastReader generates a spoken explanation and draws handwritten-style notes right on the original text — highlighting key points, circling terms, numbering steps. Listen and watch the annotations appear, like a tutor breaking it down beside you. Capture anything · Scan: point at a book, document, or screen — recognized on-device · URL: open any web page to read aloud or explain · Files: PDF / TXT / image / EPUB · Paste: drop in text and start listening instantly Made for · Anyone who'd rather listen through articles, docs, and ebooks · Language learners who want to follow along word by word · Readers who need rest for their eyes or accessibility support · People making the most of commutes, workouts, and chores Subscription Free daily read-aloud and explain quota. Upgrade to Pro for unlimited listening, unlimited explanations, all premium voices, and up to 3x speed. English & Chinese, dark mode, background playback. History stays on your device — never uploaded.
