ExoMind External Memory

ExoMind is a private external memory—a calm, searchable home for the people, events, decisions, and ideas that matter to you. Everything you capture stays on your device. No accounts, no cloud, no tracking. ExoMind is built around a simple idea: you should remember, connect, and easily recall the important things in your life. WHAT YOU CAN CAPTURE • Event Ledger — moments, meetings, and milestones on a timeline. • People Cards — who someone is to you and what's open with them. • Decision Log — what you decided, why, and how it turned out. • State Snapshots — quick check-ins on energy, focus, and tension, with a trend dashboard. • Knowledge Vault—things you've learned, surfaced in context. RECALL IT WHEN IT MATTERS • Instant search across everything you've captured. • Insights that surface patterns and connections over time. AI-POWERED CAPTURE — YOUR KEY, YOUR PROVIDER ExoMind is bring-your-own-key: connect your AI provider (OpenAI, Google, or Anthropic) using your own API key to enable chat-driven capture. Your prompts go straight from your device to your provider — we never see your key or your data. PRIVATE BY DEFAULT • All data stored locally on your device. • Export and restore local backups whenever you want. • No location, contacts, or calendar access is ever granted. ExoMind is your second mind — quietly remembering, so you don't have to.
