How do I inspect the connections around one entity?

Select or search for a node, then choose a neighborhood radius and direction. The explorer highlights nodes within that many hops and their internal connections. Read the selected entity’s notes and tags, adjust the layout, and export the graph or selected neighborhood.

Make the connections.

Is this tool free, and are my files uploaded?

This tool is free with no account required. The work happens in your browser. Your input and files are not sent to a processing server.

What are the limits and details?

Graph IDs must be unique and every edge must refer to an existing node. Labels, notes and tags are plain text. Project files save graph data and node positions locally; automatic cloud storage or collaboration is not included.

Limits: 500 nodes, 2,000 edges and 500,000 project characters. Expensive operations run in a cancellable 30-second browser worker.
