I've been meaning to build a simple writing/research tool that is basically GitHub Markdown combined with two additional features:
1. A "tagging" component at the sentence level, so I can tag individual sentences. For example, the previous sentence could be tagged with {{feature-idea}}.
2. {{feature-idea}} A semantic search capability where I can see which other sentences in all of my documents are similar to the one I'm on or the one I'm interested in.
Why, you ask? I like to keep a daily journal of ideas based on the news, blog posts, etc. I read... Similar to Caesar's commentaries[1] because ideas and observations come daily and you don't want to forget them, especially if they are tied to global/current events.
Yes, this is basically a knowledge graph... And all the tools I see that do this really overcomplicated the entire process by actually building weird graph interfaces or mind maps (which I'm not a fan of).
If anyone knows of one like this, let me know!
