Claude makes Wikipedia a conversational knowledge source in your terminal where each answer naturally opens the door to deeper questions. Start with a quick fact check, follow the thread into related topics, pull full articles for the sections that matter most, and extract references for primary source verification -- all in one continuous session. The iterative approach mirrors how real research works, letting you build understanding progressively rather than committing to a single query upfront.
