ShowMe is a ComfyUI extension that adds an annotation layer to the canvas.

It is meant for two related uses:

• Ask what a graph does, follow data flow, and inspect important nodes.
• Mark up the graph and save notes for later review.

• Manual notes with brush, arrows, shapes, highlights, and text labels.
• Ask AI can read the current workflow and place explanations near the relevant nodes.
• Separate manual and AI annotation layers, so AI explanations can be replaced without deleting manual notes.
• Annotations are saved in the workflow JSON under extra.showme_annotations.

Clone the repository into ComfyUI's custom_nodes folder:

cd ComfyUI/custom_nodes
git clone https://github.com/SKBv0/ComfyUI_ShowMe.git

Restart ComfyUI after installing.

1. In ComfyUI's bottom-right canvas controls, click the ShowMe pencil button.
2. Enable drawing when you want to mark the graph.
3. Open Ask AI for graph-aware explanations.

Ask AI can use local or command-line providers when available:

• Ollama
• Claude CLI
• Codex CLI

Ollama defaults to:

http://127.0.0.1:11434

• Exported workflows can carry ShowMe annotations with them.
• Another ComfyUI install needs ShowMe installed to display those annotations.
