Halo - Personal AI

Halo is a privacy-first personal AI app for iPhone and iPad that connects to your phone's data sources like mail, calendar, reminders, and health. It builds a private memory on your device to understand your identity, preferences, and routines, enabling personalized responses and task automation without sending data to external servers. Users bring their own AI API keys and can connect services via MCP connectors and browser automations. Features include semantic search, task automation, a command-line style workspace, and proactive daily insight generation.
