The AI answers from the file you gave it, and good tools show a citation for each answer so you can jump to the exact sentence.

Updated October 18, 2026 · By [Robert Breen](https://learn.ynteractive.com/content/about) ## Why it matters for a small business A summary answers the questions the AI thinks matter. A chat answers yours. An office manager wants the exit fee, an accounts payable clerk wants the due dates, an HR coordinator wants the start date and contingencies. Asking directly is faster than reading the whole file, and each follow-up builds on the last answer in the same conversation. Because the answer is meant to come from your document, a chat with a PDF is a simple form of [grounding](https://learn.ynteractive.com/content/glossary/grounding). It is not a guarantee. The AI can still misread a clause or fill a gap from general knowledge, so the citation is the important part: one click shows whether the PDF really says it. ## In a real lesson: AI Contract Review in 10 Minutes using Foxit AI In the free [Foxit contract review lesson](https://learn.ynteractive.com/content/review-a-client-contract-in-10-minutes-with-foxit-ai), the second question in the chat is: list every renewal and termination term with the section number and the deadline. Foxit Workspace answered with a seven-row table drawn from sections 2, 5 and 6 of the sample agreement, using 29 AI credits. You then click the citation icon on the 90-day row. The contract opens beside the chat at section 2 with the sentence highlighted. That one click is the habit the lesson is built around: the AI points, you verify.

Chat with PDF answers from the text of documents you uploaded. ### Chat with PDF vs a general chatbot A general chatbot answers from what it learned in training. A PDF chat is supposed to answer from your file, and should say so when the file does not cover the question. ## Tips - Ask for section numbers in the answer, so you can find the clause even without the citation. - Ask "what does this document not say about X?" to catch gaps. - Keep one project per client or matter, so later questions search the right files. ## Related terms [AI PDF summarizer](https://learn.ynteractive.com/content/glossary/ai-pdf-summarizer) · [AI citations](https://learn.ynteractive.com/content/glossary/ai-citations) · [Grounding](https://learn.ynteractive.com/content/glossary/grounding) · [Chat with your data](https://learn.ynteractive.com/content/glossary/chat-with-your-data) · [Retrieval-augmented generation (RAG)](https://learn.ynteractive.com/content/glossary/rag) · [Follow-up prompt](https://learn.ynteractive.com/content/glossary/follow-up-prompt) ## More AI assistants terms [ChatGPT](https://learn.ynteractive.com/content/glossary/chatgpt) · [ChatGPT data controls](https://learn.ynteractive.com/content/glossary/chatgpt-data-controls) · [ChatGPT memory](https://learn.ynteractive.com/content/glossary/chatgpt-memory) · [ChatGPT plugin](https://learn.ynteractive.com/content/glossary/chatgpt-plugin) ## Where you use it: free lessons - [AI Contract Review in 10 Minutes using Foxit AI](https://learn.ynteractive.com/content/review-a-client-contract-in-10-minutes-with-foxit-ai) (Foxit, 10 min) - [Check a Contract for Red Flags with Claude](https://learn.ynteractive.com/content/check-a-contract-for-red-flags-with-claude) (Claude, 11 min) - [Smallpdf: Get the Key Points of a 25-Page PDF in 5 Minutes](https://learn.ynteractive.com/content/smallpdf-ai-pdf-summarizer-key-points-long-pdf) (Smallpdf, 10 min) ## Frequently asked questions **Which tools let you chat with a PDF?** Many AI assistants accept PDF uploads, and PDF tools such as Foxit and Adobe Acrobat have their own AI assistants. The free Stepthrough lesson uses Foxit Workspace. **Can I chat with several PDFs at once?** Some tools let you add several files to one project and ask across them. Check the tool's limits, and ask for the file name with each answer. **Is it safe to chat with a client contract?** Only if your company allows that tool for client documents. Read the tool's AI notice first; Foxit Workspace's first-run notice says content is processed by Microsoft Azure OpenAI.
