Understands context
The project explores how rooms, people, routines and what is happening around the family could become part of one context.
NAJRA — A PRIVATE, INTELLIGENT HOME.
An intelligent presence for your home and family — understanding what matters, taking care of the everyday, and giving you more time for the things that matter.
Private, non-commercial R&D project · Local-first · Personal experimentAI demonstration: You are interacting with a simulated AI interface. This website demo is not connected to the NAJRA home system and does not access your home, devices, calendar, microphone or camera.
WHY NAJRA
Because a genuinely simple question should not hit a wall on a device that's supposed to be the smart one in the room.
“Sorry, I don't have an answer for that.”
“I don't know.”
That is the sentence that got me here. Not a missing feature, not a broken automation — just the sheer number of times a genuinely simple question becomes complicated.
NAJRA won't get everything right either. But the bar I'm building toward is a system that tries harder before it shrugs — one that actually knows your home and the people in it well enough to be useful, not just responsive.
THE VISION
Someone walks into a room and simply talks to the house, the way you'd talk to a crewmate. No apps to hunt through, no dashboards to configure — the assistant is just there, quietly useful.
The project explores how rooms, people, routines and what is happening around the family could become part of one context.
The project explores how NAJRA could handle routine tasks in the background instead of turning every action into another decision.
A mobile experience keeps the family connected when they are away from home.
Local-first is a design principle: sensitive processing is intended to remain close to home wherever technically possible.
WHAT IT DOES
Every feature exists to remove a decision, not add one. Fewer screens, fewer settings — more of the house just handling itself.
Natural, room-aware interaction — no wake-word gymnastics, no app-switching. You speak, it understands context.
Designed around a local-first architecture with security and privacy considered from the beginning.
Explores privacy-conscious presence and outdoor context, alongside routine tasks such as evening irrigation. This is a development direction, not a childcare or security service.
Explores how presence and, where technically and legally appropriate, person recognition could make alerts and automations more context-aware. This is a development direction.
A mobile app for checking in, getting notified and stepping in from wherever you are.
Core intelligence is being designed to run close to home wherever technically possible, testing how far local AI can realistically go.
The project follows a local-first privacy approach. Sensitive voice, presence and camera processing is intended to remain local wherever technically possible; actual data flows depend on the implementation of each feature.
Matter as the backbone, with explicit support for widely-used non-Matter devices such as Shelly and Homematic IP.
Explores centrally managed music experiences, including potential third-party integrations such as Spotify, subject to their APIs and terms.
Bidirectional intercom between rooms — or straight to a person wherever they are in the house.
The presence-oriented architecture may be explored for future care and home-safety use cases. It is not a medical, emergency or certified security system.
A personal, transparent experiment — mistakes, learnings and all, not a polished product pitch.
UNDER THE SURFACE
The experience hides complexity from the family. The project itself stays open about how the pieces fit together.
$ home.status() ✓ presence detected — living room ✓ presence context — family member ✓ irrigation scheduled — 20:15 local ✓ new device found — Shelly Plug ⚠ external probe blocked — 3 today $ sphere.context() → home → family → calendar → privacy & safety → local intelligence
NAJRA is an experiment in bringing local AI, Matter, Thread, Shelly, Homematic IP, cameras, audio and family context together while keeping the technical complexity out of the everyday experience.
WHY THIS PROJECT EXISTS
Inspired by the vision of the USS Enterprise — a place where humans and technology work together naturally — NAJRA started as a simple question: how close can we actually get to that idea at home?
After many years in the industry, I wanted to explore a home that understands more, is designed with privacy in mind, and genuinely supports family life.
Follow the journey →01 How far can “vibe coding” — building with AI as a real collaborator — actually take you?
02 How usable is local AI, in practice, for something real — not a toy demo?
03 What can I learn by shipping a real, working system instead of reading about one?
04 Can a local-first system speak the real world's language and set itself up without a manual?
