Show HN: Cinnamon – safer AI agent for household, private and shared context

Cinnamon is an AI agent for households of up to six people that plans, books, watches and reminds, and always asks for approval before acting. It separates a shared household space from each member's private space, keeps passwords and cards in a vault the agent cannot read, and runs each task in its own sandbox. Plans start at $9.99/month for a Personal Plan, $19.99/month for a Group Plan (up to 6 members) and $99.99/month for Group Plan Max (up to 10), after a free trial with 40 task credits.
