Upload a PDF and ask it questions in plain English. Get summaries, simple explanations and practice quizzes, with page numbers so you can check every answer.
Add your PDF. It opens on a new page with your PDF on one side and the chat on the other.
Read and ask. Read at your own pace, and ask whenever something is unclear. Try “Summarise it” or “Quiz me”.
Check the pages. Each answer lists the pages it used. Press a page number to jump straight to it.
Your PDF is read inside your browser and is never stored by this site.
To write each answer, the AI is sent only the few short passages that match your question, not the whole file. If your browser has Chrome’s built-in AI ready, that happens on your own device. Otherwise a free online AI service is used, so please avoid PDFs with private or sensitive details.
No. It’s free, with no account and no card. The free AI service can be busy at times, so if an answer doesn’t come, wait a minute and try again.
Yes, AI can make mistakes. That’s why every answer shows the pages it used. For anything important, read those pages yourself.
Scanned PDFs are really pictures of pages, so there’s no text to read yet. You can still view them, but questions won’t work. Password-protected files won’t open either, and only the first 300 pages are read.
Ask in English, Portuguese or another language and it replies in the language of your question. Quality is best in English and can vary in other languages.
