Show HN: Cinnamon AI – an agent for your family

Cinnamon is a family-oriented AI agent that plans, books, watches and reminds for you and up to five trusted people, always asking for approval before acting. It offers shared and private spaces, a vault the agent cannot read, sandboxed tasks, and a timeline of every action, with plans from $9.99/month after a 40-credit free trial. The team says it comes from people who ran AI for billions of users at Facebook, Instagram and Amazon.
