About

Every choice you regret starts the same way: a strong urge and a fast yes. A big purchase, a late night out, a snap decision — Cogent puts a smart, science-backed pause between the impulse and the action, so you decide with your rational mind, not your reflexes. HOW COGENT WORKS 1. Brain dump — Capture any urge by text or voice the moment it strikes. 2. Bias check — Cogent's AI instantly names the bias driving you (optimism bias, FOMO, scarcity, present bias) and estimates the real cost in money and time. 3. Cooling-off lock — High-stakes impulses are quarantined for a cooling-off period. The urge fades; clarity returns. 4. Socratic interrogation — When the timer ends, an AI coach asks the sharp questions that expose what you're really chasing — and whether it fits your goals. 5. Post-mortem — Rate how it played out. Cogent learns your patterns and updates your Rationality Score. WHY IT WORKS - Grounded in behavioral economics — the same biases that hijack your decisions, made visible. - The 10-10-10 framework: how will you feel in 10 minutes, 10 months, 10 years? - A Regret Ledger that turns hindsight into a real track record. - A Rationality Score that climbs from Reactive to Strategic to Cogent as your decisions sharpen. MAKE IT YOURS Set your North Star — Wealth, Focus, Health, or Relationships — and Cogent tailors every question to what you actually care about. COGENT PRO Unlock unlimited brain dumps, voice conversations with your AI coach, your full decision history, and persona-tuned interrogations. Includes a 7-day free trial for new subscribers.
