CastReader reads a user’s PDFs, EPUBs, DOCX and TXT files, webpages, images, and supported reading-service content aloud with synchronized highlighting and scrolling. It can explain a passage with AI annotations, read public YouTube caption text when captions are available, and connect eligible Kindle, WeRead, Google Play Books, Kobo, or O’Reilly accounts. The app does not provide book content or play or download YouTube video and audio. Supported OCR runs on-device, while Bengali, Marathi, Punjabi, and Tamil image recognition uses Google cloud OCR after sign-in. Pro offers unlimited standard-voice reading, AI explanations, premium voices, and faster playback; cloned voices have a separate 120-minute monthly allowance. The U.S. App Store lists two monthly Pro prices ($4.99 and $9.99) and two yearly prices ($34.99 and $59.99); confirm which plan and offer is available. The developer privacy policy says text for speech and AI explanations may be processed by its service, and the Apple privacy label lists tracking and linked account, audio, usage, and diagnostic data. Requires iOS 17.6 or later.
