Turn research papers into AI-generated audio conversations
Upload a PDF or point the tool at a web article and receive a spoken back-and-forth between two AI hosts rather than a flat read-aloud.
Distinct synthetic voices take turns introducing, summarising and questioning the source material, which makes complex topics easier to follow.
The system extracts the central arguments and findings instead of reading the document line by line, producing a shorter, digestible overview.
Generated sessions are saved to your account so you can revisit, replay or continue listening where you left off.
Text to speech and voice AI across every device
Listen to books, PDFs, documents and web pages read aloud in a large library of lifelike AI voices.
Dictate instead of typing in almost any app, across Google Docs, Gmail, Slack, Outlook and more.
Turn documents or a short prompt into an AI podcast, and get instant summaries of what you are reading.
Use the web app, Chrome and Edge extensions, and native iOS, Android, Mac and Windows apps.
