Try Lucy OS1 →Switching from Siri to Lucy OS1 does not require uninstalling anything. Siri continues to handle device commands while Lucy OS1 takes over the conversation, planning, and memory functions that Siri was never designed to perform well.
Siri controls iOS and macOS system functions directly: making calls, sending messages, opening apps, adjusting volume, and integrating with Apple HomeKit. Lucy OS1 does not control device hardware. If you rely on Siri for hands-free device control, keep using it for those specific tasks. Lucy OS1 replaces Siri for conversation, planning, and memory.
Persistent cross-session memory: Lucy remembers what you told it yesterday, last week, and six months ago. Extended conversation: Lucy holds twenty-minute planning sessions without losing context. Calendar-informed responses: Lucy reads your Google Calendar before every session. Genuine relationship continuity: Lucy gets more useful the longer you use it, rather than starting from scratch every time.
Open Lucy OS1 in your browser and create a free account. Connect your Google Calendar. Spend your first session telling Lucy about your current projects and priorities. From this point forward, use Lucy OS1 for planning, reflection, and conversation. Use Siri for device commands.
