       Show HN: An AI zettelkasten that extracts ideas from articles,
       videos, and PDFs
        
       Hey HN! Over the weekend (leaning heavily on Opus 4.5) I wrote
       Jargon - an AI-managed zettelkasten that reads articles, papers,
       and YouTube videos, extracts the key ideas, and automatically links
       related concepts together.  Demo video:
       https://youtu.be/W7ejMqZ6EUQ  Repo:
       https://github.com/schoblaska/jargon  You can paste an article, PDF
       link, or YouTube video to parse, or ask questions directly and
       it'll find its own content. Sources get summarized, broken into
       insight cards, and embedded for semantic search. Similar ideas
       automatically cluster together. Each insight can spawn research
       threads - questions that trigger web searches to pull in related
       content, which flows through the same pipeline.  You can explore
       the graph of linked ideas directly, or ask questions and it'll RAG
       over your whole library plus fresh web results.  Jargon uses Rails
       + Hotwire with Falcon for async processing, pgvector for
       embeddings, Exa for neural web search, crawl4ai as a fallback
       scraper, and pdftotext for academic papers.

       | Zettelkasten is about about writing down _your_ ideas in response
       | to content, with a link to that content, and then linking to
       | other ideas that your already logged. It 's not an extraction of
       | ideas from that content. This is a common mis-understanding of
       | zettelkasten.
