It rejects gamification and inspirational language in favor of clinical analysis, hard constraints, and value alignment. CORE MODULES: BASELINE: Free-form intake to extract sources of drain and avoided decisions. VALUES: Forced-choice extraction to define your 5–7 non-negotiable principles. CONSTRAINTS: Map your hard limits in money, time, and energy. DIRECTION: Define a single 6–12 month trajectory. No multiple goals; one path. DECISION TOOL: Analyze options based on cost, reversibility, and alignment. DRIFT DETECTION: Weekly logs that plainly flag actions contradicting your values. PRINCIPLES: Neutral UI: No emojis, no rewards, no streaks. Privacy-First: Local storage by default. No data selling. Reasoning-First: Text-heavy, analytical interface. Stop seeking motivation. Start mapping your constraints.
