This pulls answers from your personal wiki by searching the index, following wikilinks between related pages, and synthesizing what it finds into formatted responses. It knows to use qmd for search on larger wikis, cites everything with wikilink syntax, and matches answer format to your question type (comparison gets a table, exploration gets narrative). The smart bit is it offers to save valuable synthesis back into the wiki as new pages, so good answers compound over time instead of disappearing into chat history. Works best when your wiki is already organized with proper index entries and interlinked concepts.
