Skimrとは
Premium Academic Assistant with Sage UI. Free Chrome extension that turns any article or PDF into Cliff Notes, AI flashcards, and a 4-question recall quiz, in seconds.
Built for students, researchers, and serious readers who want to read less and remember more. Skimr runs locally in your browser. No account, no API keys, no tracking.
WHY ACTIVE RECALL? The biggest meta-analysis on study strategies found that highlighting and re-reading have near-zero effect on long-term retention. The methods that actually work — testing yourself and spaced practice — have always been hard because someone has to write the questions. Skimr removes that friction.
WHAT SKIMR DOES:
- AI Cliff Notes — get the core takeaways from any article, paper, or PDF in 5 seconds
- Auto-generated flashcards — ready to study, no manual deck building
- 4-question recall quiz — find your gaps before the exam does
- Custom AI Q&A — ask anything about the page, grounded in the actual content
- Vault — save summaries locally on your device
- Markdown / PDF export — works with Anki, Obsidian, Notion, NotebookLM

Built by Anu Tewari, a mechanical engineer (ex-Rivian, ex-Volkswagen) who got tired of nodding along to articles and forgetting them by the next week. Reach me at skimr.app or @SkimrApp on X.
