CastReader
Read webpages, PDFs, Kindle, and AI answers with synchronized highlighting of key content
About CastReader
CastReader reads webpages, PDFs, Kindle ebooks, and AI answers, with synchronized highlighting during playback. When a paragraph is difficult to understand, Read & Explain breaks down the available text in your language and points back to the source. The tool supports 9 languages, with German coverage for voice selection, the extension interface, and Kindle OCR; when documents are parsed in the browser, the original files stay on the device, and cloned-voice playback sends only the paragraph being read.
