Read full description

Executive OS is a private AI Chief of Staff that runs sealed inside your phone. No cloud. No analytics. No remote backend. Every founder, CEO, and high-net-worth operator faces the same cognitive load: too many decisions, too little structured reasoning, too much data leaking into other people's servers. Executive OS solves this by putting your private operating system on a single device, encrypted with AES-GCM 256, sealed by your biometric. CHOOSE YOUR TERM Monthly $19.99 · Yearly $49.99 · Lifetime $99.99 one-time. Everyone who purchased Executive OS while it was a paid app keeps permanent access at no cost — forever. A FOUNDER SERIES, NUMBERED The first one thousand activations are issued sequential serial numbers. DAILY AI EXECUTIVE BRIEFING A private Chief of Staff distills your priorities each morning. Listen in a luxury synthesized voice. WEALTH OPERATING SYSTEM Track net worth across real estate, cash, investments, equity, vehicles — in six currencies. AI Wealth Analyst flags concentration and liquidity gaps. CALIBRATION — JUDGMENT YOU CAN MEASURE State your own confidence on every call. Months later, record what actually happened. Executive OS scores you with a Brier score, plots your calibration curve, and splits it by domain — so you learn where your judgment holds and where it does not. Before you commit to a number, it shows you what happened the last times you felt exactly this certain. EXECUTIVE SEARCH One field across every decision, task, retrospective, holding and playbook. Entirely on device. Vault secrets are never indexed. DECISION ENGINE WITH COACH MODE Strategic questions answered with structured reasoning, risk-reward framing, confidence scoring. Coach Mode runs a Socratic interview before you act. Fifteen pre-built decision archetypes. CEO PLAYBOOKS Thirteen hand-written essays — first 100 days, M&A negotiation, down round, firing senior leader, board management, founder burnout, calibration, Series B prep, PR crisis. WEEKLY RETROSPECTIVE Friday evening five-question ritual. Compounds into year-end calibration. SECURE VAULT Credentials, API keys, contracts. AES-GCM 256. Screenshot detection. Time-locked entries. FOUNDER TOOLS Cap table, runway with default-alive check, OKR tracker, 1:1 prep, board prep, AI investor updates. VOICE JOURNAL & DOCUMENT OCR Record voice memos, on-device speech recognition, photo OCR into the vault. On-device Apple Intelligence summarization — no API key needed. STANDBY MODE DASHBOARD Bedside night display with today's aphorism and tomorrow's first priority. INTERACTIVE LOCK SCREEN WIDGETS Tap to record a decision from the lock screen. YEAR-END EXECUTIVE REPORT Book-format typeset PDF every December: net worth, allocation, decision calibration, AI commentary. PARANOIA-GRADE SECURITY Biometric-bound master key. Self-destruct. Dead-man's switch. Decoy profiles. Tamper-evident audit log. Excluded from iCloud. PRIVATE BY ENGINEERING We collect zero data. Anthropic integration runs against your own API key. On-device Apple Intelligence needs no key at all. For the cognitive demands of leadership. TERMS Executive OS Pro — monthly ($19.99), yearly ($49.99), or lifetime ($99.99, one-time). Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period.
