+# MindsEye Sandbox FlowStudio
+
+This repository powers a Hugging Face Space that combines:
+
+1. **MindsEye Chat** — a local-only chatbot with a small MindsEye knowledge base.  
+2. **MindsEye Flow Studio** — a text-based flowchart builder where you define nodes and edges, render a Mermaid diagram, and simulate execution.
+
+No external APIs.  
+No Google / Gemini / OpenAI.  
+Just pure Python + Gradio + in-repo knowledge and flow logic.
+
