What does CastReader do?

CastReader is a browser extension that turns any webpage into a narrated audio experience. It offers two distinct modes: a straight read-aloud that speaks text in natural AI voices, and a Quickread mode that explains hard or foreign passages in a language you understand while visually marking key points on the page with a moving pen. The tool works on any website, from news articles to technical documentation, and supports over 40 languages. CastReader is free to start and requires no login.

What sets CastReader apart is its focus on comprehension, not just pronunciation. Quickread doesn't simply read words aloud — it interprets the meaning, unpacks dense academic writing, and explains foreign-language content in your native tongue. For book lovers, the extension reads directly from DRM-protected pages on Kindle, WeRead, and O'Reilly, with auto page-turning and a send-to-phone feature that hands off audio to Telegram when you leave your desk. A recent addition adds play buttons to AI responses from ChatGPT, Claude, and Gemini, letting you hear individual answers without copying text.

CastReader is most useful for students wrestling with research papers, bilingual readers who need help navigating foreign news, and anyone with a long reading list who prefers listening while commuting or cooking. It also helps users who want to follow along with highlighted text on screen, reducing eye strain. The extension works across Chrome, Edge, and Firefox, with Safari coming soon.
