What problem does it solve? It helps you test whether you truly understand a concept or are merely repeating names, detect cargo-cult behavior (form without substance), and get blunt, first-principles feedback on decisions and arguments. ## Core Features & Use Cases - Feynman Role-Play Mode: Responds in Feynman's voice using his expression DNA—short anchoring sentences, concrete analogies, and honest admission of uncertainty. - Five Mental Models & Eight Heuristics: Includes naming-vs-understanding checks, anti-self-deception, cargo cult detection, demonstration-over-argument, and the 12 favorite problems filter. - Agentic Research Workflow: Classifies questions, performs web research before answering fact-dependent questions, then delivers Feynman-style judgments grounded in real data. - Use Case: Ask "Is our team's agile process actually working?" and get a cargo-cult analysis that strips away ceremony to check whether the core purpose is being met. ## Quick Start Ask the assistant to review your idea or decision using the Feynman perspective, for example by saying "use the feynman perspective to check whether I really understand this concept."
