🏠 homemgmt-ng
Plan your whole house in 3D – and every compartment of every piece of furniture becomes a storage location.

What is it?
Where are the batteries? Is there any dish soap left? What expires this week? homemgmt-ng answers these questions
by modeling your house: you draw floors, walls and rooms, place furniture in them – and every compartment and every
drawer automatically becomes a location with its own code (KU-C2 = kitchen, furniture C, compartment 2). You
check items in and take them out with a click, a QR scan, your voice or the AI assistant. The search "Where is …?"
lights up the matches in the house.
Everything runs on your own computer or server: one Node process, one SQLite file, no cloud.
The app is available in German and English. The language follows your browser and can be switched under More → Settings.
The AI assistant
Say, type or photograph what happened – the assistant books it into the right compartment.
- 📷 Photograph a shelf = inventory done: take a photo of the shelf or drawer, ideally with the compartment's QR
label in the picture. The assistant recognizes all items in the photo, creates new ones, increases existing ones
and checks everything into that compartment in one step – from four transactions on, only after you confirm. If you
like, it stores the photo with the item.
- 🎤 Just say it: "3 cans of tomatoes into the pantry cabinet, best before 05/2027" – it understands compartments
by name ("kitchen fridge top") and reads its answers aloud.
- 🔎 Ask and find: "Where is the cordless drill?", "What expires this week?" – with "Show in house".
- 🏷️ QR labels in photos are read by the app itself: "this goes here" is enough.
- 🛒 Shopping and prices: add to the list, tick off, "Where is butter cheapest right now?" (price research with
retailer, store and source).
- 🖥️ Talk to the wall terminal: press "Speak", tap your tile, go – limited to search, transactions and shopping there.
- ↩️ Safe: every transaction can be undone, the assistant acts with the person's permissions; works with any
OpenAI-compatible provider (OpenRouter, LiteLLM …), plus an MCP server for Claude & co. – details under
AI assistant and MCP server.

.glb
- 3D view with PBR materials, daylight by time of day, photorealistic path tracing and walk-through like
in a game (including stairs between floors)
- House location: address or coordinates and north direction – the sun is where it is outside
📦 Inventory
- Check in, take out, move, undo with a complete history per item
- QR scan with the phone camera: compartment code + item = check in, the same item twice = take out
- Labels & QR signs to print – or as multicolour 3D print models (3MF)
- Shopping list: consumables land on it automatically when taken out, share via WhatsApp
- Household tasks: recurring, assigned to people, attached to compartments ("replace filter"), can be ticked off
on the wall terminal too
- Expiry with warnings, containers (a box inside the toolbox), photos per item
- Insights, export/import as Excel, automatic backups

- Overview as the home page: quick actions, shopping list to tick off, what expires soon, fill level per floor,
recently moved
- Poor Wi-Fi: transactions are queued ("2 transactions waiting") and synced automatically – the server never books twice
- Multiple people signing in with a tile + PIN/password or email, "Plan the house" permission per person
- Settings per person: home page, house in 2D or 3D first, light/dark, font size
🖥️ Wall terminal
A tablet on the wall becomes the control center for everyone in the house – without personal sign-in.
