Cass is the assistant inside the CastHub at Home app, on its own tab. You say what you want in plain words, Cass works out which TVs and albums you mean, shows you the change as a card, and does it when you tap Do it. Cass is there so that the fiddly parts of running TVs in three houses take one sentence instead of six screens.

What you can ask Cass to do

Show an album on a TV: “Put Summer 2026 on the porch TV.” Put the family calendar on a TV: “Put our calendar on the kitchen TV.” Cass asks which view, shows it, and proposes the change. Set quiet hours: “Turn the den TV off at 10 and on at 7.” Switch a TV off, on, or restart it, and look at what it is showing: “What is on Grandma’s TV?” These four work on an Amazon Signage Stick. Make a card: “Make a countdown to Eli’s birthday,” “Make a card that says happy anniversary.” Cass shows the picture first. Make a new album, rename a TV or an album, change how many seconds each item shows.

How a change happens

Cass reads the family’s own TVs, albums, calendars and people, so it knows that “the porch TV” is in the lake house and that “the kids’ album” is called Eli’s soccer. For anything that changes something, Cass writes a card that says exactly what will happen, in family words. You tap Do it, or Not now. If the result is not what you wanted, tell Cass and it puts it back. Reading and answering questions needs no card.

What Cass will not do

Cass never deletes anything: not an album, not a photo, not a TV, not a person. Cass does not send a message that takes over a TV; a message for the family becomes a card in an album. Cass does not change who is in the family, and does not touch anything outside the family’s own TVs and albums. Picking photos by looking at them, and inviting people, are not things Cass does at launch.

Your photos stay yours

Cass does not look at the photos in an album. When you ask what a TV is showing, the picture is put in front of you, the person who asked; Cass does not read it. Conversations are per person, not one thread for the whole family: a contributor does not read the owner’s chat, and the other way round.

Cass answers questions too

What the app can do, which TVs work, what the plan costs, how the trial works, why the calendar is not showing on the Samsung. Cass answers from the same facts as this site. When something needs a person, Cass passes it to the team, who reply by email to the address on the family. Help is this chat and email; there is no phone line, and there are no demos.

Where Cass comes from

CastHub, the company behind CastHub at Home, runs screens for businesses across many sites, and its business customers manage those screens through AI assistants. Cass is the family version of the same idea, with family words (TV, home, album, person), a short list of things it may do, and a card before every change. Back to CastHub at Home.

Frequently asked questions

What can I ask Cass to do?

Show an album on a TV, rename a TV or an album, change how many seconds each item shows, switch a TV off, on or restart it and look at what it shows (on an Amazon Signage Stick), set quiet hours, put the family calendar into an album, make a countdown, birthday or message card, and make a new album. Cass also answers questions about the app, the price and the trial.

Does anything happen without me saying so?

No. Cass shows you the change as a card before anything happens. You tap Do it or Not now. If a change turns out wrong, Cass puts it back.

What will Cass not do?

Delete anything: an album, a photo, a TV, a person. Send a message that takes over a TV. Change who is in the family. Anything outside the family’s own TVs and albums.

Does Cass see our photos?

No. Cass does not look at the photos in an album. When you ask what a TV is showing, the picture is put in front of you; Cass does not read it.

Can my mother use Cass too?

Yes. Everyone in the family has Cass in their own app, and conversations are per person: a contributor does not see the owner’s chat and the other way round.
