Users are leveraging Claude with Opus 4.8 to create a personal operating system (OS) dashboard that manages tasks, calendars, finances, and more. This setup allows for voice prompts via Telegram and features a cloud memory system that evolves over time. The process involves designing the OS in Claude Design, building it in Claude Code, setting up cloud memory with platforms like Supabase, and optionally adding voice control through Telegram bots. Users can customize the system by linking apps such as Google Calendar and finance APIs, creating a seamless, personalized productivity tool.
