I've been working on this tool that lets you build a personal knowledge graph from articles, blog posts, podcasts, YouTube videos, and other content you find interesting online. You can safely forget everything and trust that Recall will resurface it when something new that is related comes up. Looking forward to your thoughts and feedback on how it could be improved!
The original version of Recall was posted last year nov on HN: https://news.ycombinator.com/item?id=33425947
Since then I have pivoted to a browser extension.
