Document Q&A: ask questions and get cited answers

Document Q&A means querying a file the way you'd ask a colleague — “What are the payment terms?” — instead of scrolling pages or guessing keywords with Ctrl+F. Upload your documents and Doxy finds the answer and writes it back to you in seconds.

Good Q&A is only useful if you can trust it. Doxy answers only from the documents you provide and shows the exact passages it used, so every answer links back to its source and nothing is invented.

Group related files into a project and ask questions across all of them at once — Doxy retrieves the most relevant passages wherever they live. It works the same whether you chat with a PDF or chat with many documents together.

Behind the scenes, Doxy splits each document into passages, finds the ones most relevant to your question, and feeds them to the model — an approach called retrieval-augmented generation. The same engine powers AI document chat and turns Doxy into a capable AI research assistant.

Ready to go beyond the basics? Our guide Q&A Over Your Documents With Citations walks through asking better questions and verifying every answer against the source passage. For the technology behind it, What Is RAG?explains retrieval-augmented generation — why cited Q&A stays grounded where a general chatbot guesses. And when the real problem is a document that's simply too long, How to Summarize Long PDFs With AI shows how to condense it first and then drill into the details with follow-up questions. All three are short, practical reads that pair well with a free Doxy project, so you can try each technique on your own files as you go, starting with a single upload and a handful of questions.
