Chat with PDFs, books, websites, YouTube videos and podcasts
Upload PDFs, EPUB books, text files or paste a web article link, YouTube video or podcast episode and chat with the content in one interface.
Responses are backed by the passages they were drawn from, so you can check the source text instead of taking an answer on faith.
Large documents are summarised with their whole context in mind, which matters for ebooks and lengthy reports.
The system supports many languages and replies in the language of your question.
