 Turn any topic into a folder of interlinked, deep-dive study notes: a generated index hub, mermaid concept maps, and wiki-links that light up Obsidian's graph view. Powered by an AI CLI (Claude Code, Gemini, or Codex) or a fully local Ollama model. It also explains selections into linked notes and enhances text in place. Desktop only. Works on Windows, macOS, and Linux.
 
+One prompt ("why is the dollar the world's reserve currency?") produced this index hub and the 16 linked notes behind it:

The plugin creates a new note in the same folder, writes the AI output into it, and replaces your selection with a `[[wiki-link]]`. If a note with that name already exists, it links to it instead. You can select several modes at once to generate multiple takes on the same topic.
