Key takeaway
Complex documents — those with competing arguments, technical detail, or massive length — need a multi-step approach. Chain-of-thought prompting lets AI reason through complexity before summarizing. Chunking lets you handle documents too long for a single prompt. Hierarchical summaries give you a one-liner, a paragraph, and a detailed breakdown in one shot.
Practice Exercise
Hands-on practice — do this now to lock in what you learned
Open an AI assistant and try this:
Find a complex document — a long article with multiple perspectives, a report with several sections, or a dense academic paper. Try the hierarchical summary prompt: ask for a one-sentence version, a 5-bullet version, and a 300-word detailed version. Notice how each level serves a different need, and how specifying all three in one prompt forces the AI to identify what truly matters.
