This appears to be the README file for an Obsidian plugin called InfraNodus. The plugin uses natural language processing and network science algorithms to provide insights into the structure and content of notes in an Obsidian vault. Here's a summary of what the plugin does:

1. It analyzes the text in your Obsidian notes and creates a graph visualization of the concepts, ideas, and relationships between them.
2. The graph is colored-coded by topic clusters, allowing you to see which topics are most important or densely connected nodes closer together on the force-atlas layout).
3. You can also generate AI summaries based on network science metrics.
4. Bookmarks: It allows bookmarking groups for context menu will appear in the bookmarks panel.

The plugin is still beta stage so data collection about the feature of extension you use, but no any information from your vault, but not Obsidian (no export settings - what name your graph with content will generate AI summaries and/or save automatically via API (your confirm, faster it) saving into the selected in bookmarks

Here are some most urgent feature requests for their team: contextual menus for bookmarks expose search results API
