Chat with your PDFs — summaries, citations and multi-document search in seconds
Every response links back to the page it came from and highlights the supporting passage, so you can check the evidence rather than take the answer on trust.
Generate instant summaries of lengthy PDFs to decide what deserves a close read and what you can skim.
Upload several documents and query them together, finding a specific detail without opening files one by one.
Apply tags to PDFs and then chat with a group defined by a tag, keeping distinct projects separated.
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.
