Substy AI

ego is a personal AI agent that lives across your browser, desktop, and phone. It remembers your projects, preferences, and work patterns, and runs multiple tasks in parallel 24/7. You can interact with ego via voice (just hold fn and speak), iMessage, Dynamic Island, a desktop agent, or its AI browser. Hand it tasks like summarizing tabs, replying to emails, conducting deep research, building apps from descriptions, generating content in your tone, filling forms, or monitoring web changes. ego works while you're away, delivering finished files and pinging you for approvals. Unlike chatbots, ego doesn't just chat—it acts inside your real accounts and files, learning from your actual work activities. It builds persistent memory so it gets better at knowing you over time. Unlike AI browsers, ego runs tasks in the background 24/7, across devices, and handles entire workflows beyond the browser. Your data is encrypted, synced across devices, and never used for training AI models. ego is made for everyone, not just developers, and requires zero configuration.
