Do you have the same experience like me? When something come into my mind(for example, "waht is survivorship bias"), it's so familiar, but just don't know where I have read it, that feeling is too bad! I'm not a smart guy, and I don't have the ability to remember all things I have read. So, I'm want to kown if there's a tool that I can put all things in it(articles, videos, images, podcasts, etc. I don't want to manage them, just want a place to throw them in), and when I input a keyword like "meditation", it will offer me the sources I had put in. I think the difficulities is to parse the videos, images and audios instead of text files.
