# K-Plex plugin for Obsidian K-Plex is a spatial knowledge navigator for Obsidian. It's the successor of ExcaliBrain. It shows a focused view around one active note, and places related notes in predictable directions, so the position of a note carries meaning: - Parents above - Children below - Friends and previous notes on the left - Challengers and next notes on the right - Siblings in a separate area on the right Unlike the [[Graph view core plugin for Obsidian]], the layout is deterministic (no force-directed physics). And unlike ExcaliBrain, it doesn't need the [[Excalidraw plugin for Obsidian]] or the [[Dataview plugin for Obsidian]] at runtime. Key features: - Click a node to center it, double-click to open it - Create relationships by dragging from directional gates; they're stored in the YAML frontmatter (customizable ontology fields: parent, child, friend, challenger, previous, next, hidden) - Explainable connections: right-click a connector to see why it was placed there (frontmatter, inline ontology, links, folders, tags, URLs) - Companion sidecar: a native Obsidian tab that stays in sync with the centered note - Graph lenses to filter and style nodes by keywords, tags, and note types - Section outlining for Markdown notes - Fuzzy search across titles, aliases, and paths - Incremental, IndexedDB-backed index for fast startup in large vaults - Works on desktop, tablet, and mobile (requires Obsidian 1.13.0+) The plugin is open source (AGPL-3.0). This plugin has been created, and is maintained by [[Zsolt Viczián]]. ## References - https://community.obsidian.md/plugins/k-plex - https://github.com/zsviczian/kplex ## Related - [[Excalidraw plugin for Obsidian]] - [[Dataview plugin for Obsidian]] - [[Graph view core plugin for Obsidian]] - [[Visual thinking]] - [[Mind Maps]] - [[Obsidian Starter Kit]]
