Happytat is your household's private memory — one place for what you have, what matters, and what needs doing. Its agents keep an eye on things and help take care of what comes next.
Everything important about your household, in one place. Not trapped in someone's memory. Not scattered across a dozen apps. And not owned by an AI company.
Happytat keeps the context that makes a home understandable — not just files, but what they mean, who they belong to, what they're connected to, and what happens next.
Identity, important records, preferences, responsibilities and the things each person needs.
Vehicles, appliances, property, warranties, receipts, purchases and household assets.
Insurance, accounts, documents, renewals, appointments, bills and important dates.
Supplies, meals, routines, maintenance, plans and the small loops that keep life moving.
Happytat's memory belongs to your household, not to a conversation with a particular model. Add something once and it becomes useful context wherever it belongs.
Happytat updates the policy, keeps the document connected to the vehicle, and knows when it needs attention again.
It can live with the appliance it belongs to, alongside the purchase date, warranty and service history.
The everyday household memory changes too. Happytat can keep the shopping list and future planning current.
Your household database, documents, relationships and history stay in the Happytat instance you control.
Use the models that make sense for you — hosted or local. Your household does not have to start over when the model changes.
An agent gets the context required for its job, not unrestricted access to everything your household knows.
Because Happytat has durable household context, its agents can notice changes, connect information, prepare work and take permitted actions without making you explain your life from scratch every time.
The notice matches an existing policy and household vehicle. Happytat has prepared the update without changing anything important behind your back.
Happytat is designed to be self-hosted. The source of truth for your household can stay on infrastructure you control.
When you choose to use an external AI model, Happytat can provide the context needed for that task instead of handing over the whole household.
See how a household feels when it has a memory of its own.
