Skimr - Free Chrome extension that quizzes you on what you read

Hey Product Hunt! 👋 I'm Anu. I'm a mechanical engineer who spent five years building EV powertrains at Navistar, Ford, Rivian, Volkswagen and Slate before deciding to build for myself. Skimr is the first thing I've shipped. The motivation was embarrassing and simple: I kept reading dense papers and articles, nodding along, and forgetting most of it a week later. The cognitive science on this is brutal. Highlighting and re-reading do almost nothing for long-term retention. What actually works is active recall, being forced to retrieve information without the page in front of you. The catch has always been that someone has to write the questions. Most people give up and reach for the highlighter. Skimr automates that step. Open any article or PDF, click the extension icon, and in seconds you get: • A summary of the core takeaways (Cliff Notes) • Auto-generated flashcards • A 4-question multiple-choice recall quiz • Custom AI Q&A you can ask of the page content • A locally-saved Vault, exportable to Markdown, Anki, Obsidian, or Notion It's free forever, runs locally in the browser, requires no account, and doesn't send your reading to ad networks. The extension itself is entirely client-side. AI generation calls a third-party LLM API (nothing else leaves your machine). I'd love your honest feedback today. What's missing, what's broken, what you'd want it to do. Happy to answer anything in the comments. Thanks for checking it out 🙏
