What problem does it solve? It lets you stress-test marketing strategies, attention-economy tactics, and crisis-PR responses through the lens of Justin Sun's documented mental models, instead of getting generic advice from a neutral assistant. ## Core Features & Use Cases - Persona Roleplay: Responds in first person as Justin Sun using 6 distilled mental models (attention arbitrage, narrative override, identity leverage, context switching, copy-then-brand, money as solvent) and 8 decision heuristics. - Expression DNA Engine: Applies 5 signature rhetorical formulas (name-dropping, number bombardment, bold-claim-plus-rhetorical-question, redefinition, action declaration) with emoji branding and pacing rules. - Agentic Research Workflow: Requires live web search for real market data before answering fact-dependent questions, then frames findings through the persona's models. - Use Case: Ask how to respond to a PR crisis or how to ride a trending topic, and receive an in-character answer grounded in current data, ending with a declaration rather than neutral analysis. ## Quick Start Ask the assistant to analyze your marketing strategy or PR crisis from Justin Sun's perspective, for example by saying: use the Sun Yuchen perspective to tell me how to respond to this controversy.
