Fire TV · Ring · Alexa+

The television as the care surface for the person being cared for.

Wick lives on the one screen an older person already watches for more than four hours a day, and asks her to install nothing, learn nothing and wear nothing. She answers with one button on the remote she already holds, and the family sees only what she has agreed to share.

No account and no hardware needed. Try the demo makes you Sarah, her daughter, in a demo home.

Disclaimer: her television in a browser tab is for quick testing only. Wick is a Fire TV app: judge it on the Vega Virtual Device or the Fire OS build in the Android TV emulator, as we did (Setup), or on a Fire TV. We ran it on a real Fire TV Stick 4K Select.

Recorded on a real Fire TV Stick 4K Select, beside the family app. The waiting is cut; nothing is staged.

The idea

Products for ageing at home are built for the caregiver. Wick turns that around.

A phone app full of alerts, checked by a daughter three hundred miles away. Wick lives instead on the screen she already watches for more than four hours a day (BLS American Time Use Survey, 2025), and she stays in charge.

Built for the caregiver

  • A phone app full of alerts, checked from far away
  • Cameras and sensors that watch her
  • Wearables she forgets to charge
  • Decisions made about her, not with her

Built for her

  • Calm cards on the television she already uses
  • The front door only; no camera looks inside the home
  • One button on the remote she already holds
  • The family sees only what she has agreed to share

The people in the demo. Margaret lives alone. Sarah, her daughter, lives far away. Maria is her carer. Try the demo makes you Sarah.

What it does

Three things, done quietly.

The door

A ring at the door puts a card on her television in about two seconds, then the doorbell's picture and one plain sentence about who is there. If another app is in front, Wick still tells her: a system toast on Vega, a notification on Fire OS. Only the door may interrupt.

The family

Sarah asks Alexa+ "How's Mum been this week?" and gets a short, honest answer. Notes go to Margaret's television and wait for a natural break; she replies with one button.

The rhythm

Wick learns what a normal week looks like in this house, so it stays quiet when nothing is wrong and can say "that's up from last week" and mean it.

When she is watching another app. No app can draw over another on Vega or Fire OS, so Wick's cards appear only while Wick is on screen. The door still reaches her over anything: a system toast on Vega, a heads-up on Fire OS. A note never interrupts. On Fire OS it waits quietly in the Notification Center, never over her programme; Vega has no quiet place to leave it, so it waits in Wick. Either way it is on her screen the moment she opens Wick.

Features

Sixteen features on top. Each one says what it never does.

Every one has a rule that protects her, enforced in code.

  • Her day

    Her home screen opens on her: "Good morning, Margaret.", the date, and who is coming, such as "Maria usually comes tomorrow at 9 am." The films are under it.

    Never says anyone came, or shows a visit the door has not been told of.

  • Ask Sarah to look

    One button on the door card asks Sarah to look at the same picture. Sarah's answer appears under her name.

    Never shows Sarah the door unless Margaret asks.

  • Shall I tell Sarah?

    When a day is unusual, such as the carer not coming, Wick asks Margaret first and shows her the exact sentence it would send.

    Never tells the family anything she keeps to herself.

  • Calm points

    A note waits for the credits, a pause, or a quiet cut measured in the film itself. The film holds while she reads it. See the map.

    Never interrupts a scene. No model chooses the moment.

  • Watch together

    Sarah invites her to a film. When Margaret presses Start the film, Sarah's screen follows hers.

    Never lets anyone else touch her remote.

  • The light in the window

    Sarah sees one thing about today: whether Margaret's day has begun. Margaret can put it out.

    Never says when, where or what. Her home screen shows who looked in.

  • Hold for Sarah

    Holding OK for two seconds asks one person to ring her. If they don't answer in three minutes, the next person is asked.

    Never calls anyone itself or raises an alarm.

  • The visit, witnessed

    After the carer leaves, the television asks: "Maria was here from 9:02 to 9:47. Is this right?"

    Never treats a visit as confirmed until she says so.

  • Sarah's television

    Sarah can connect her own Fire TV. It shows Margaret's light, door requests, the week and shared films.

    Never becomes Margaret's television or sees more than Sarah may.

  • Her language

    Sarah can ask for Spanish. Nothing changes until Margaret says yes on her own screen.

    Never machine-translates a sentence she consents by.

  • The mantelpiece

    Sarah sends a picture. Margaret can keep it, and kept pictures fill her idle screen.

    Never tells Sarah whether she kept it.

  • Read to me

    Play reads the card on screen aloud, in her language (Amazon Polly).

    Never speaks unless she asks.

  • Easier to see

    Larger text, at 40-point minimum, and higher contrast, at 21:1, across every screen.

    Never shrinks a word to make it fit.

  • Visit errands

    Sarah says "The plumber is coming Thursday at ten — let Mum know." Wick's agent shows her the plan; after her yes, a note waits for Margaret's natural break, the door card later says "Sarah arranged a visit for about now", Margaret is reminded that morning, and Sarah is told when the door rang or that nobody came.

    Never says the plumber came. It says someone rang around then; whether it was them is Margaret's to say.

  • The visit pass

    Sarah sends the doctor a link. On the step the doctor presses I'm at the door, and Margaret's television says "Doctor Rossi is at your door. They confirmed it on their phone just now." A ring nobody expected says "You don't have to open."

    Never tells her she can open, shows the visitor anything about her, or lets a model decide who is there.

  • The Sunday brief

    Margaret's week, written by agents from counted facts and checked twice, ends with one thing Sarah could do, with one button: write a note, arrange a visit or watch a film together.

    Never guesses how she feels, or suggests anything the week's facts don't support.

The family reaches all of it through 26 MCP tools, and through an agent on Amazon Bedrock AgentCore that uses those same tools with the family member's own token and asks before every write. Every call checks again that Margaret still allows that person.

See it

On the Vega Virtual Device and the Fire OS build.

Her daughter's side

Two screens, one conversation.

Sarah talks to Wick the way she would talk to Alexa+. Everything she reads comes from Wick's tools, through the Guardian.

  1. She asks how Mum's week wentA short, honest answer, written from counted facts.
  2. She sends a noteIt waits on Margaret's television for the next natural break.
  3. Margaret answers with one pressHer reply comes back in Sarah's conversation.

Try it

Five steps, in two browser tabs.

No account and no hardware are needed.

Disclaimer: her television in a browser tab is for quick testing only. Wick is a Fire TV app: judge it on the Vega Virtual Device or the Fire OS build in the Android TV emulator, as we did (Setup), or on a Fire TV. We ran it on a real Fire TV Stick 4K Select.

  1. Open her television

    The keyboard is the remote: arrows move, Enter is OK, Esc is Back, Space is Play/Pause, and Enter held for two seconds is Hold for Sarah.

  2. Become Sarah

    In the family app, choose Try the demo and enter the code shown on the television, or point a phone at the QR code beside it. Each press is a new demo session, with six weeks of simulated history.

    Family app
  3. Let her allow you

    On the television, press Allow Sarah when it appears, about twenty seconds after pairing. Then ask the family app anything, for example "How has my mum been this week?"

  4. Send a note during a film

    The note waits. Pause, or let Big Buck Bunny reach its calm point at 1:29, and it appears. Space reads it aloud; Enter replies.

  5. Ring the stand-in doorbell

    In the family app, choose who is there. The door card appears at once and the film waits under it, then the picture and one sentence about it.

The same flow runs on the Vega Virtual Device and on the Fire OS build in the Android TV emulator (docs/SETUP.md).

How it is built

The television renders and never decides.

The edge authenticates and answers Ring within its five-second budget. The agents do the reasoning. All of it is in Terraform, deployed by GitHub Actions over OIDC.

Wick's architecture. Margaret's home: her Fire TV (Vega app or Fire OS build) talks to the edge over AWS IoT Core MQTT or an API Gateway WebSocket; the Ring doorbell sends a signed webhook to API Gateway HTTP. The edge puts events on EventBridge for 26 Lambda functions and one Bedrock AgentCore runtime with three Strands agents (the door graph on Nova Lite, the family assistant, the Sunday brief graph), with Step Functions for visit errands, SQS, EventBridge Scheduler and a Bedrock Guardrail; the agents fetch Ring's frame, live view and chime and send cards out to the television. Sarah's family app, the Alexa+ add-on and her own Fire TV reach the Wick server on App Runner over MCP with OAuth 2.1, through the Guardian. Memory is DynamoDB, S3 and CloudFront, AgentCore Memory and Secrets Manager; models are Amazon Bedrock plus Rekognition, Polly, Translate and Transcribe.

Technology

Vega OS
The resident's app in React Native for Vega. A headless service shows the door over other apps, media controls make a platform pause count as a natural break, w3cmedia plays the films and the door's live view, and Content Personalization is told what she watches as she watches it.
Fire OS
The same source through four small adapters, with an Android foreground service for the door, and her film as Android's MediaSession, so "Alexa, pause" and the remote's media keys go through the same rules as on Vega.
Ring Partner API
OAuth link, webhooks, recorded frames and live view (WebRTC bridged to HLS for the television).
Alexa+ MCP
An MCP server (spec 2025-11-25, Streamable HTTP, OAuth 2.1) with 26 tools. The add-on surface is partner-only, so a simulated Alexa+ app calls it, as the rules allow.
Amazon Bedrock
Nova Lite describes the door's picture in one sentence. Claude Sonnet 4.5 is the family's assistant and writes the Sunday brief from numbers already counted. A Bedrock Guardrail checks both. No model runs inside a tool.
AgentCore + Strands
Three agents in AgentCore Runtime: the door's Strands graphs, the family assistant (an MCP client with the member's own token, pausing for their yes, with AgentCore Memory) and the Sunday brief graph: analyst, writer, check, suggester.
AWS
Lambda, API Gateway, IoT Core, EventBridge and Scheduler, Step Functions, SQS, App Runner, Cognito, DynamoDB, S3, CloudFront, Secrets Manager, Rekognition, Polly, Translate and Transcribe.

Why Amazon

Wick needs a trusted screen in the room, a doorbell with a real developer API, and an assistant the family already uses. Only Amazon has all three.

Privacy and trust

Privacy is the product, not a compliance section.

  • No camera looks inside the home

    Ring is used at the front door only.

  • She sees everything the family sees

    On her own television, and she can remove it. She reaches it at any time from her light on the home screen, and can stop Wick there: everything it keeps about her home is deleted, and her family's app says so.

  • Some things are never shared

    Health, money, relationships and location, under any setting. A deterministic content gate, the Guardian, also checks every string a family member reads against a written list, and property tests run it through the real tool paths. It catches what the list names.

  • No guessing about her

    No mood detection, no wellness scores, no fall detection, no chatbot on the television. The reasons are in docs/WICK.md §6.

What is real, and what is simulated

Built on the simulators, then run on a real Fire TV Stick 4K Select.

  • TelevisionThe Vega app on a real Fire TV Stick 4K Select (Vega OS), as the demo video shows, and on the Vega Virtual Device; the Fire OS build on the Android TV emulator. A browser version runs the same cards and break rules, for quick testing only.
  • DoorbellRing's Developer Playground, behind Ring's real API. It sends no webhooks and has no chime, so demo homes use a clearly labelled stand-in doorbell with made-up visitors.
  • Alexa+A simulated surface that signs in with OAuth and calls the real MCP server.
  • HouseholdA demo home with six weeks of simulated history, marked as simulated everywhere.
  • FilmsBlender Foundation's open films.

Real and deployed

Everything between those ends: the AWS stack, the MCP server, the agents and models, the Guardian, accounts and pairing.

Not yet seen on real hardware: a Ring doorbell, or a spoken "Alexa, pause".

She stays in charge. Her family stays close.
