Summarise a Research Paper in Three Levels of Detail

Different people need different amounts of a research paper, and reading it three times isn't an option. This produces the same paper at three levels: the one-sentence version, the one-paragraph briefing covering question, method and finding, and a fuller account. Pick the depth that fits whoever you're presenting to next.

**Level 2: The briefing (one paragraph)**
Cover the research question, method, key finding, and one limitation in under 100 words.

**Level 3: The deep dive (structured notes)**
