I built an app to organize fragmented learning

Hacker News

Hi HN, I built an app to solve a problem I kept running into: I’d read great articles or watch insightful YouTube videos, but within a few days, I’d forget most of what I learned. Taking detailed notes felt like a chore, and I'd rarely revisit them anyway. To solve my own problem, I built Curio. It's an iOS app designed for low-effort capture and active recall. How it works: 1. Share any article or YouTube link to the app. 2. It automatically extracts key ideas as bullet points and links them back to the original context (the specific paragraph or timestamp). 3. The app then generates quizzes from your saved points to help you actually retain the information. The core idea is to move beyond passive bookmarking into active learning, without the heavy lifting of manual note-taking. I'd love to hear your feedback, especially on the quality of the key idea extraction and whether this is a problem you face too. App Store: https://apps.apple.com/app/curio-save-learn-retain/id6745309... More information: https://www.curio-app.com (Currently the app is iOS only)
