This is cool, but how about local semantic search through tens of thousands articles and books. Sure I'm not the first, there should be some tools already.

I'm not an expert, but I'll do it for learning. Then open source if it works. As far as I understand this approach requires a vector database and LLM which doesn't have to be big. Technically it can be implemented as local web server. Should be easy to use, just type and get a sorted by relevance list.
Although, atm I am only using retrieval without any LLM involved. Might try integrating if it significantly improves UX without compromising speeds.
