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.
AI teammate that records, transcribes and summarizes every meeting
Automatically joins Zoom, Google Meet, Microsoft Teams and other calls to record, transcribe with speaker labels, and write summaries with decisions and action items.
Ask questions in Slack or the app and get answers drawn from past meetings, email and connected work tools, with links back to the source.
Track deal health, talk-time trends, sentiment and topics across calls to inform sales, recruiting and coaching decisions.
Connects to conferencing, email, CRM, project management, storage and collaboration tools so notes and tasks flow where your team already works.
