Nexus: Local Knowledge Graph & Highlighter

About

Nexus is a privacy-first, local-only browser extension that transforms the way you research, connect, and organize knowledge online. 

Instead of letting bookmarks gather digital dust, Nexus lets you capture and synthesize ideas directly from your browser, visualizing them as a beautiful, interactive 2D/3D knowledge graph.

Key Features:
- **Instant Inline Highlighting**: Highlight any text on any webpage. Right-click to save and categorize with customized tags.
- **Rich Local Notes**: Attach context-aware notes, summaries, and questions to page nodes or individual highlights.
- **Interactive Knowledge Graph**: View your research as a force-directed visual graph. Identify clusters, explore bi-directional connections, and navigate your saved vault visually.
- **Polished Light & Dark Modes**: Read and research comfortably day or night with a gorgeous, high-contrast, responsive interface.
- **Universal Markdown & Obsidian Export**: Easily export your entire local database as Obsidian-compatible Markdown files (ZIP) or standard JSON.
- **100% Local & Private**: No cloud APIs, no external CDNs, and no tracking. All data is processed and stored securely on your local machine.
