Lurny

Lurny is a Chrome extension built for people who read and watch a lot online and want it to stick. Rather than bookmarking an article and never returning, you use its StubIT feature to "Lurnify" the page or video you are looking at, and the AI condenses it into a focused, bite-sized knowledge object Lurny calls a Lurny. Each Lurny is short, structured and paired with assessments, so complex material is broken down into digestible lessons instead of an intimidating wall of text.

Its retention model is called ROSI — Repetition over Optimally Spaced Intervals — which schedules review sessions inspired by the Fibonacci sequence so that knowledge moves from short-term to long-term memory. Alongside this, Quizzify is an AI quiz generator that builds multiple-choice questions from the content of each Lurny to test understanding and reinforce it. A community layer, including a reflective-questioning feature called Socritic, lets learners share insights and think more critically about what they study.

The pitch is efficiency and flexibility: hours of passive reading become minutes of active learning, at your own pace, with multilingual support. The extension is published by carillonmedia.com and is small and lightweight to install.
