A private AI console that keeps your files and conversations on your own device
Models run locally, so chats and prompts are processed on the device rather than in a remote data centre.
Chat, search, notes and the document library remain accessible with no connection, making the device useful offline.
Choose 1 TB or 2 TB of solid-state storage for photos, videos and documents, all kept inside the device.
Private Chat, Deep Search, Smart Notes, Document Library, Private Gallery and Media Player are built for the hardware from the ground up.
A private, memory-powered AI assistant you own and customize
A custom-built memory system that retains you, your people, preferences and work across every conversation, rather than resetting each session.
Connect Google Workspace, Slack, Notion, your filesystem and community plugins so the assistant can send emails, manage calendars, browse, create slides and run research.
Set permissions so sensitive actions like emailing new contacts or modifying key files require approval until you mark them trusted.
Switch between OpenAI, Anthropic, Gemini or open-weight models via Ollama at any time, keeping you free of a single vendor lock-in.
