One calm place for your home, your business and your money. A steward that answers only to you.
An iPad in the hall, readable from two metres. Scenes for the morning, the evening and the office, changed with a touch or a word.
Every tile opens to the detail behind it. Anything it cannot show, you ask, by voice or by typing.
Low glare, day and night. An alert appears once, says what happened and offers one thing to do.
Your steward speaks like a very good chief of staff: the state of things first, then what needs you, then one offer. Exact figures. Short sentences. Nothing to scroll past.
“I’ll never send, pay or unlock anything without asking you.”
Good morning.
The house is secure. Two things in the estate want your eye.
Shall I draft the cancellation for the car insurance?
An example brief, for an example household.
It works for you and nobody else. Your own AI if you wish, your own accounts, and a plain account of where your data goes.
It reports; it does not chat. No small talk, no exclamation marks, no noise on the screen.
The house, the business, the money, the inbox and the diary, seen from one place rather than ten apps.
Dark, low-glare screens and slow, smooth motion. It speaks up only when something matters.
Your phone shows the scenes you arranged for the hall, flowed into one column. What needs you sits at the top. Ask sits at the bottom.
Money, messages, access and deletion always come to you as one plain line: what will happen, to whom, for how much. Approve, or not now. The small things simply happen.
A screen in the hall can switch a light. A lock tapped there waits for an adult’s phone.
A business is its own space with its own members. The household never sees its books, and your steward moves between them only when you ask.
The house: security, cameras, access, devices, sound and network.
Business and money: companies, accounts, invoices, inbox and diary.
Castald works for you, not for a platform. Nothing is locked to one ecosystem.
Your calendar, mail, bank feeds, cameras and energy supplier stay in your name. Castald connects to them; it never holds them for you.
A managed model and voice from the start, or your own key for the model you prefer. Change it whenever you like.
Passwords and keys live in a sealed vault. No screen and no tool ever reads one back.
Connects to Google, Microsoft 365, iCloud, Xero, QuickBooks, Stripe, Octopus Energy, Home Assistant, UniFi, Telegram and WhatsApp Business, among others.

Everything: home and estate together, with a steward that moves between them.
Terms on applicationA screen for the wall, usually an iPad by the front door, and the accounts you already use. Castald runs in the browser on a laptop or television too, and on your phone.
No. It sits above it. Lights, locks and sensors stay in Home Assistant; Castald shows them, switches them and asks before anything that matters.
Each member of the household has a role. Guests and children see less and can do less. A business is a separate space that the household never sees.
Only what your connected accounts show it and what you choose to tell it. You can review and remove anything it has remembered.
Whatever you like. You name your steward on the first day, and that is the name it answers to.
