The Geulo plugin integrates your liked YouTube videos into Obsidian, enhancing content review and organization. It retrieves all your liked YouTube videos using the YouTube Data API v3, allowing you to search, sort, and view them in the sidebar. Additionally, you can add videos directly to your daily notes for easy reference. Upcoming features include batch updating daily notes with liked videos and displaying popular videos. The plugin is designed to make re-watching valuable content easier, leveraging Obsidian's knowledge base capabilities to deepen learning and review habits.
