Cinnamon plans, books, watches and reminds, for you and up to five people you trust. It always asks before it acts.
Everything in the household space is visible to the household: the ski trip, the chore rota, the Sunday digest. Everything in your personal space is yours alone. Cinnamon never mixes them, and it tells you which one you're in.
Every email, booking, purchase or share stops for your approval and shows exactly what will happen. Your passwords and cards live in a vault the agent can't read. Every action is in a timeline you can inspect, export or delete.
Every new account starts with 40 free task credits so you can run real tasks for yourself or your household right away.
Every new account starts with a free

Cinnamon is our cat: orange over one ear, black over the other, white everywhere else, green eyes, and quietly in charge of the house. While we were building an AI agent for families, she was the obvious name for the project. The name stuck, and so did her colours: the cream, the orange and the black on this page are hers.
She is also how the app tells you what it's doing. When the cat's eyes are open, Cinnamon is working on something for you. When they're closed, the task is done or waiting, and nothing happens until you say so. Like the real one, she asks before she jumps on the counter.
Built by infrastructure veterans and systems architects with decades of experience delivering distributed platforms and AI systems to hundreds of millions of users.
Michael is the founder and CEO of Cinnamon. He brings over two decades of technical leadership building high-availability distributed systems, large-scale ML infrastructure, and real-time consumer platforms. Michael specializes in taking complex systems from 0-to-1, with an operational focus on privacy-preserving architectures, accelerator economics, and dependable agentic workflows.
Prior to founding Cinnamon, Michael built Meta’s ML capacity forecasting and management framework for Instagram and Reality Labs through global GPU constraints, owned core streaming protocols serving tens of millions of concurrent live viewers at Amazon Prime Video, and co-founded edge-AI video analytics company Monitoreal (deployed across airports and critical transit infrastructure) as well as global CDN pioneer Advection (scaled to 1B+ monthly streams).
Household tasks involve real family calendars, medical appointments, school forms, and utility bills. We architect Cinnamon with strict multi-tenant data boundaries, zero unauthorized cross-principal data leakage, and a verified approval loop before any action is executed.
