About the Chat with PDF (AI)
Sometimes you do not need a summary, just one answer: the notice period in a lease, the dosage in a leaflet, the deadline in a grant call. Here you upload a PDF once and ask questions about it in a conversation. The AI is told to answer only from the document and to say plainly when the answer is not in it, rather than guessing.
What you can do
- Ask a question of up to 2,000 characters about any PDF up to 25 MB.
- Keep asking follow-ups; earlier questions and answers are sent along so the model understands context like "and what about the second option?".
- Get answers drawn from the document itself, with a clear "not in the document" when it has nothing to go on.
- See the estimated credit cost of each question before you send it.
When it works best
- Finding a specific clause, figure or date in a long contract, manual or report.
- Checking how a policy handles your situation, such as a refund or cancellation.
- Studying from lecture notes or a textbook chapter by asking it questions.
Things to know
- Sign-in with a verified email is required, plus either credits or your own Anthropic or Google API key.
- The whole PDF is sent to the AI provider with every question, so each question costs about as much as reading the document again.
- Between questions, your PDF is kept in temporary storage on our server and deleted automatically after about 30 minutes.
- Answers can still be wrong. For legal, medical or financial decisions, confirm the passage in the PDF yourself.
