Read aloud webpages, PDFs, Kindle books and AI answers with synced highlighting
Natural AI voices narrate webpages, PDFs, ebooks and documents while each spoken word is highlighted and the page auto-scrolls, so you never lose your place.
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.
Preview real samples of dozens of voices across many languages, and create private cloned voices that Pro members can apply to their own PDF, EPUB, Word and TXT files.
Listen to anything. Beautifully.
Peech parses a document before narrating it — recognising headings, quotes, dialogue, tables, code and scanned page furniture so each element is read the way it should be.
Pick from a library of narrator personas designed for different genres, including ideas and essays, business writing, reportage, fantasy, romance and philosophy, and switch voices mid-chapter.
Accept PDF, EPUB, DOCX, PPTX, TXT, email, saved articles, photos of printed pages and scans, and bring in ebooks you already own or long AI chat threads.
Peech Immersive casts a full set of character voices and a switchable soundscape, aimed at publishers who want audiobook versions of a title produced quickly.
