Geo Nodes Guide shows documentation inside the Geometry Nodes editor when you hover over any node, so there's no tab-switching to look up what a node does or how to use it. Each tooltip includes a description, common uses, pitfalls to avoid, and real workflow examples.
The add-on documents 332 nodes, covering mesh operations, curves, instances, volumes, simulations, and more. Pitfall warnings flag quirks such as which inputs expect radians versus degrees, or when you need to realize instances first. "Often Combined With" suggestions point to nodes that pair well together.
Tooltips dismiss with ESC and can be toggled on or off at any time. A built-in feedback button lets you report issues or suggest improvements for specific nodes. Geo Nodes Guide is open source under the GPL v3, and anyone is welcome to explore the code, contribute improvements, or add translations. It requires Blender 5.0.
