I face this problem so badly! And I needed a solution that worked according to my needs. This is why I have been building a tool called Sunchay. It will auto-analyze anything that I have saved, generate AI summaries, keywords and have an article reader built right into it. It will then send me emails about the things that I have saved recently and how they are all connected.
You are welcome to try it and share anything feedback that you may have. At the moment, I can save markdown notes, websites, files, anything, and it shows everything in a nice grid view while also generating AI summaries, like TLDR and keywords (which I can then search for.)
I will try to add those features / fix those bugs that you suggest. :)
