    You talk, and it automatically builds a visual network of your beliefs, thoughts, desires, and more. The system extracts concepts like beliefs, emotions, and cognitive distortions, then updates a force-directed graph showing how everything connects. Recurring nodes naturally drift toward the center as the graph expands, revealing your core themes. It isn’t intended for therapeutic use. It’s a tool that makes you introspect and helps uncover the driving factors behind your issues instead of trying to solve the problem and suggest solutions (although you can ask it for solutions when needed).…
