MCP Chat Visualizer

What it does

MCP Chat Visualizer converts complex AI conversations into interactive, hierarchical mind maps. Instead of scrolling through long chat histories, it allows you to visualize the flow of logic, key topics, and supporting details in a structured map format.

Key features

• Automatic Mapping: Generates JSON-based mind maps directly from the conversation context.
• Hierarchical Structure: Organizes data into Root, Category, and Leaf nodes for clear information architecture.
• No External APIs: Performs all visualization logic via LLM prompting, requiring no additional API keys.
• Deep Analysis: Supports mappings up to 3-4 levels deep to capture nuanced details.
