This connects to your Readwise Reader library and quizzes you on articles, essays, or books you've recently read. It can scan your archive for good quiz candidates or work with something specific you name. Questions mix comprehension with application, asking you to connect ideas to your work or spot what the author missed. If you drop a reader_persona.md file in your working directory, it'll personalize questions around your job and interests. Grading is direct, quotes the source material, and fills in what you missed. One question at a time, three to five total depending on document length. Honest take: it's useful if you're trying to move things from "I skimmed this" to "I actually retained something," but only if you're willing to type out real answers instead of just nodding along.
