Normally the AI answers from what it already knows. But you can also **give it your own documents** — a PDF, a report, meeting notes — and then ask questions about *those*. The AI reads your files and answers based on what's actually in them. The technical name for this is **RAG** (retrieval-augmented generation), but you don't need to remember that. Just think of it as: > **"Read this, then answer my questions about it."** ## When is this useful? * "What does our return policy say about damaged items?" (from a policy PDF) * "Summarize the key decisions from these meeting notes." * "Find every mention of pricing in this contract." * "What are the main points across these 5 documents?" Instead of reading everything yourself, you ask, and the AI finds the answer inside your files. ## How to use it Go to the place where you add knowledge — this is usually inside an **App** (on its **Knowledge** or **Data** section) or your **Storage** area. Click **Upload** and choose your file. An upload area for adding documents to the AI's knowledge After uploading, the AI needs a moment to "read" the document (you might see a status like *processing* or *ready*). This usually takes a few seconds to a minute. Now ask about the content in plain words: > *According to the uploaded handbook, how many vacation days do new employees get?* A chat answer that cites the uploaded document Good answers often show **where** they came from in your document, so you can trust and verify them. Look for a citation or a highlighted snippet. ## Tips for good results * **Upload clean files.** Clear, text-based PDFs work best. Very blurry scans are harder to read. * **Ask specific questions.** "What's the refund window?" beats "tell me about refunds." * **Add more documents** for broader questions — the AI can look across all of them. * **Ask for the source.** "Which section is that from?" helps you double-check. Your uploaded documents stay in your workspace. They're used to answer *your* questions, not shared publicly. ## Next step Package all of this — a model, instructions, and your documents — into a reusable helper.
