Plan a trip
Resorts, flights for four, a shared itinerary everyone can react to.
Tidy the inbox
A morning digest of what actually needs a reply. Drafts ready to send.
Run the calendar
Appointments, forms, renewals. Reminders that land before, not after.
Watch a price
Tell it a number. It waits, then tells you when it's time.
Shared and private
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.
Eyes open
A task is running. Cinnamon is researching, comparing, waiting on a reply.
Eyes closed
Done, or paused until something changes. Nothing happens without you.

Personal · Only you
Safety & Memory
Cinnamon doesn't build a hidden profile from your chats. When it learns a useful detail—like a nut allergy, your home ZIP, or preferred airlines—it saves a plain-English fact to that specific space. Household facts stay with the family; Personal facts stay private to you. You can review, edit, or delete any memory in one tap, and every external action still stops for your approval first.
Inspect, edit, or delete
Every saved fact is written in plain English. Fix a detail, add one yourself, or delete it in one tap.
Scoped by space
Household facts stay in the family group. Personal Space memories are strictly locked to you alone.
Approve before it acts
Every email draft, calendar invite, or external action stops for your explicit OK before anything happens.
Your data, your rules
No ads, never used to train AI models, and OAuth tokens stay vaulted where prompts can't read them.

Why Cinnamon?
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.

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).

FAQ
No. Every account starts with a private space that's yours alone. When you're ready, invite up to five family members or close friends into a group; shared tasks show up for everyone, your private space stays private.
The tasks Cinnamon runs, and a memory of preferences you can read, edit or delete at any time. We do not store your conversation history with Cinnamon once a session ends. Passwords and payment details are never stored where Cinnamon can read them. We don't show ads and don't train models on your data.
Monitor and summarize your connected Gmail mailbox (surfacing financial transactions, school notices, youth sports, and other family activities), prepare draft inquiry emails in your Gmail Drafts folder when exploring options and reaching out to providers, check your schedule and help you add important events to your calendar, research and compare products and local services, design tailored meal plans and exercise programs, and help you prepare for job interviews. Cinnamon never sends emails on its own, modifies your calendar directly, or spends money without your direct action.
Only what you put in the shared space. A job search, a gift or an appointment in your personal space is invisible to the group, and Cinnamon never mixes the two. You choose where each task lives when you start it.
Every new account starts with a free trial (25 task credits—enough to complete 15–25 tasks depending on complexity, no credit card required). After your trial, plans start at $9.99/month for the Personal Plan (50 credits/mo for 1 member), $19.99/month for the Group Plan (150 shared credits/mo for up to 6 members), and $99.99/month for Group Plan Max (1,000 shared credits/mo for up to 10 members). Both Group Plans include every member’s private Personal Space for $0.
Because “free” usually means you’re paying with your data. We don’t harvest your personal information or use it to train ad targeting. Instead, Cinnamon is funded by the people who use it, which lets us run a sustainable business and keep the experience fast, responsive, and high quality.
