Private PDF chat

Chat with your PDFs without handing them to a chatbot.

You want to ask your PDFs questions the way you would ask a person. You do not want the contract, statement or medical letter passing through a tool you know little about. Here are the two private ways Étoiles does it.

Question and answer, with the source

Étoiles is built around questions and answers rather than open-ended chat. You ask something about your documents; it answers only from them and shows the passage. It is not a general chatbot: it will not draft an essay or answer questions about the world. That narrowness is what lets it point to where an answer came from.

Two private ways to do it

Questions to put to a PDF

• "What is the total on the invoice and when is it due?"
• "What does the warranty exclude?"
• "Which of my documents mention the 2025 renovation?"
• "What did the doctor ask me to do before the next visit?"

Your whole library is searched, so you do not need to open a PDF first. See ask your PDFs for more on how answers and citations work.

Being honest about private

In Étoiles Cloud your documents are not zero-knowledge: they are processed in memory to search and write answers, and your questions are sent to our answer and embedding providers. We do not store your questions and we do not use your content to train AI models. The free app sends nothing to us. The privacy policy has the detail.

Étoiles answers are written by AI and can be wrong. Open the cited passage to check before you rely on an answer.
