This turns your conversation into a permanent wiki note instead of letting it vanish into chat history. Say "save this" or "capture this" and it extracts the actual knowledge, not a transcript of what was said. It classifies the content (synthesis, concept, decision, or reference), rewrites it as declarative knowledge with provenance markers for what's stated versus inferred, and files it in the correct Obsidian vault category. It also updates your index and creates wikilinks to related pages. The rewriting step is the real work here: it transforms "we decided X because Y" into "X is preferred because Y", which is what you actually want to find six months later when you've forgotten the conversation ever happened.
