Linkedin: Github: Mail: Website: Project Link: I learn a lot from YouTube, and I wanted to build a tool that could help me retain and apply that knowledge. So, I built a second brain using AI, which helps me learn better and faster! 🚀 This is a chrome extension which automatically transcribes summarizes the content of the videos I watch. 🧠 Not just that, it can also save the markdown files for easy editing. ✨ I decided to take things a little further and added the feature for it to directly store the transcriptions and summary to Capacities as well! 📝 Is this extension free?

For the longer / custom summaries, I am working on adding this feature, and once it's done, it will be available to use! Could you provide some examples of how you see yourself using the custom summary options?
