Read long documents with AI
AI can help you get through a long document, if you ask targeted questions and check the answers against the pages.
Most chatbots let you upload or paste long files: a contract, a report, a manual. Start by asking for a map: "List the main sections and what each one covers, with page or section numbers."
Then ask the questions you actually have. "What does this say about cancelling early?" "Which parts affect someone renting alone?" Targeted questions beat "summarise this", which tends to flatten the details that matter to you.
Ask it to quote. "Give the exact sentence and where it is." Then find that sentence yourself. Models sometimes blend two sections, miss a footnote, or skim parts of very long files.
For contracts, insurance, health and legal papers, AI helps you understand and prepare questions. The decision still deserves a careful read of the key clauses and, when the stakes are real, advice from a professional.

Map, ask, verify
- 1. Pick a long document you need to understand. Remove personal details if it has any.
- 2. Use the prompt below.
- 3. Open the document and check two of the quotes it gives you.
I have uploaded [DOCUMENT]. 1. List its main sections in one line each. 2. Answer my questions: [QUESTION 1], [QUESTION 2]. For each answer, quote the exact sentence it is based on and say where it is. If the document does not say, write "not stated".
