Do a week of market research in one hour” · you could be next

Pick any long public report (an annual report, a government study, a McKinsey PDF) and turn it into a one-page brief your CEO would actually read.

What your page must include

  • The 3 decisions this report should trigger
  • The 5 numbers that matter, with why
  • What the report gets wrong or leaves out

How to do it

Feed the report to Claude, ChatGPT or Gemini. Direct it like an analyst: push for judgment, not summary. A brief that takes a position beats a neutral digest.
