Lumen Chat puts the world's most powerful AI models in your pocket โ€” all in one beautifully designed app. Chat with multiple AI providers, snap photos for instant identification, search the web, build websites, and analyze documents โ€” all powered by cutting-edge artificial intelligence. โ— MULTI-MODEL AI CHAT Unlike apps locked to a single AI, Lumen Chat connects you to multiple leading AI models from different providers. Switch between reasoning models, fast models, and multimodal models with a single tap to find the best answer for every question. โ— AI COUNCIL โ€” INDUSTRY FIRST Can't decide which AI to trust? Summon the AI Council. Your question is sent to multiple AI models simultaneously. Each model responds independently, then a synthesized "Council Verdict" combines the strongest insights into one superior answer. No other app offers this. โ— CAMERA VISION Point your camera at anything โ€” a plant, a math equation, a product label, a painting, food, or text โ€” and get instant AI-powered identification, analysis, and detailed information. โ— DEEP THINKING MODE Activate reasoning mode and watch the AI think step-by-step through complex problems including math, logic, coding challenges, and scientific questions. โ— BUILT-IN WEB SEARCH Search the web and receive AI-summarized answers without leaving the app. No additional accounts required. โ— AI WEBSITE BUILDER Describe any website in plain English and watch AI generate a complete site with HTML, CSS, and JavaScript.

About

Cogent AI

Read full description

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 โ€” 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 โ€” Capture any urge by text or voice the moment it strikes. 2. Bias check โ€” 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 โ€” High-stakes impulses are quarantined for a cooling-off period. The urge fades; clarity returns. 4. Socratic interrogation โ€” When the timer ends, an AI coach asks the sharp questions that expose what you're really chasing โ€” and whether it fits your goals. 5. Post-mortem โ€” Rate how it played out. Cogent learns your patterns and updates your Rationality Score. WHY IT WORKS - Grounded in behavioral economics โ€” 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 โ€” Wealth, Focus, Health, or Relationships โ€” 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. Payment is charged to your Apple ID at confirmation of purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period; your account is charged for renewal within 24 hours prior to the end of the period. Manage or cancel anytime in your App Store account settings. Terms of Use: https://iocogent.com/terms.html Privacy Policy: https://iocogent.com/privacy.html
