Free Chrome extension that turns any article or PDF into AI Cliff Notes, flashcards, and a quick recall quiz — so you actually retain what you read.
Auto-summarize any article or PDF into key concepts, claims, and citations. The signal, not the noise.
Study-ready flashcards generated from the source material. Tap to reveal answers.
Multiple-choice quiz to test what stuck. See exactly which concepts you missed and why.
Custom Q&A grounded in the page itself — no hallucinations from the wider web.
Organize your study cards in one place. Export to PDF or Markdown for Obsidian, Notion, or NotebookLM.
Side-panel UI stays out of your way until you need it. No tab switching, no copy-paste.
Most "AI study tools" require an account, send your reading history to their servers, and reserve the right to train on your data. Skimr does the opposite.
Install the extension and use it. No sign-up, no email, no password, no profile to create.
Your Cliff Notes, flashcards, quizzes, and Vault stay on your device. Nothing syncs to any server.
No analytics, no ad pixels, no "anonymized" data collection in the background.
No subscription, no upgrade tier, no paywall. The full feature set is permanently free.
Yes. The full feature set is free forever. No tier, no upsell, no "Pro" version locked behind a paywall.
No. There's no account, no email field, no password, no login screen. You install the extension and use it.
Locally on your device. Your Vault, flashcards, summaries, and quizzes never leave your browser.
Yes. Open any PDF in Chrome and Skimr can summarize, flashcard, and quiz it the same way it does for web articles.
Yes. Vault entries can be exported as PDF or Markdown — works directly with Obsidian, Notion, NotebookLM, and any other knowledge-base tool.
Anu Tewari. Originally a side project to fix my own habit of forgetting articles a week after reading them. Skimr makes active recall, the most evidence-backed study technique in cognitive science, actually frictionless to use.
