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.

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.
