Instead of only reading a hard passage, CastReader summarises and unpacks its meaning in the language you know best, with an animated pen marking the key lines in the original text.
Works across Kindle, WeRead, Google Play Books, O'Reilly and other book platforms, news and newsletter sites, Google Docs, Notion, Gmail, plus ChatGPT, Claude, Gemini, DeepSeek and Kimi answers.
