CastReader reads web articles, Kindle Cloud Reader books, PDFs, Notion and more aloud in natural AI voices across 40+ languages, with real-time word highlighting.
Its Read & Explain mode does more than narrate — it explains the text in plain language as it reads, marks up the key passages like a teacher with a highlighter, and shows synced subtitles.
