CastReader is built for focused reading — eyes and ears tracking together. The active paragraph highlights, the page auto-scrolls, you stay locked in. Perfect for long articles, research papers, and books that demand sustained attention. ——— 📚 WHERE IT WORKS CastReader works on any webpage with readable text. Specifically optimized for: • Long-form articles, blogs, and news sites — clean extraction that skips ads and navigation. • PDF files opened in your browser. • Web-based e-book readers and reading subscriptions, including pages that render text on canvas (we use OCR for those). • Academic papers and research preprints — smart extractors skip references and figure captions. • AI assistant conversations. • Cloud documents and online editors. If a page has readable text, CastReader can read it aloud. ——— 🎯 THREE WAYS TO LISTEN 1. Click the CastReader icon in your browser toolbar — reads the whole page aloud. 2. Hit the Listen button that appears on supported sites. 3. Select any text and tap the play button — listens to just that selection. ——— 🎙️ VOICE QUALITY Powered by Kokoro AI, a state-of-the-art open voice model.
