You could take a look at Obsidian [1], or similar knowledge management tools. There is certainly a lot of movement in the plugin ecosystem right now, for example the obsidian-canvas-llm-extender [2], which (likely) does what you're asking for.

I always found Obsidian and whatever other tools a huge time investment by itself with more effort to use them than actually getting the managed knowledge.

Same for Anki, Notion, Zettelkatsen etc. Even ignoring the setup cost, it costs as much effort to insert in something as it does to retrieve it. The value prop tends to be low for individuals.
