# Recl > Recl is a paid memory system for people who learn from long-form content. Save a YouTube video, article, PDF, podcast, or note; Recl produces a structured AI summary with key takeaways and timestamps, builds quizzes from it, and sends spaced-repetition recall prompts via Telegram or Discord until the idea sticks. Everything lands in one semantically searchable library with a knowledge graph linking items by shared topics. Recl is not a free note-taking app. There is no free tier: $10/week, $30/month, $99/year — every plan unlocks every feature. ## Product - [Pricing](https://www.recl.app/pricing): 3 plans, all features on every plan, no free tier. - [Public library](https://library.recl.app/): free AI summaries of channels, playlists, and books. No account required. - [About](https://www.recl.app/about): who builds Recl. ## Writing - [How to remember what you watch on YouTube](https://www.recl.app/blog/remember-what-you-watch): Why long-form video fades within weeks, what the research says actually fixes it, and a review schedule you can keep without it becoming a second job. - [Spaced repetition explained, with the actual intervals](https://www.recl.app/blog/spaced-repetition-explained): What the spacing effect is, why the right gap depends on how long you need to remember something, and how to pick intervals without running an algorithm in your head. - [Building a second brain from video, not just articles](https://www.recl.app/blog/second-brain-from-youtube): Most personal knowledge systems assume you are working with text you can highlight. Here is what changes when the source is a three-hour podcast, and how to build one that survives it. - [Learning from video](https://www.recl.app/blog/topics/learning-from-video): Getting real knowledge out of YouTube, podcasts and lectures — and keeping it after the tab closes. - [Memory & spaced repetition](https://www.recl.app/blog/topics/memory): How forgetting works, why review timing matters more than review volume, and what the research actually says. - [Second brain & note-taking](https://www.recl.app/blog/topics/second-brain): Building a personal knowledge system around material you did not write yourself. ## Docs - [Documentation](https://www.recl.app/docs) - [Quick start](https://www.recl.app/docs/getting-started) - [Saving content](https://www.recl.app/docs/saving-content) - [Recall and review](https://www.recl.app/docs/recall-and-review) - [Knowledge graph](https://www.recl.app/docs/knowledge-graph) - [Mobile app](https://www.recl.app/docs/mobile-app) - [Browser extension](https://www.recl.app/docs/browser-extension) - [Telegram and Discord](https://www.recl.app/docs/telegram-and-discord) - [Help centre](https://www.recl.app/help) ## Machine-readable - [Pricing as markdown](https://www.recl.app/pricing.md) - [Full context](https://www.recl.app/llms-full.txt) ## Optional - [Changelog](https://www.recl.app/changelog) - [Privacy policy](https://www.recl.app/privacy) - [Terms of service](https://www.recl.app/terms) - [Contact](https://www.recl.app/contact): hello@recl.app
