The floor plan: rooms drawn as rectangles, with the containers inside them.

Your home, the way you draw it

Sketch the rooms or import a floor plan as a PNG, then mark the places inside them — wardrobes, shelves, boxes, drawers — with the names you actually use: “Shelf 2”, “Red cables box”. Or pick them from a list: they are laid out on the plan for you, already furnished.

Tell it. Ask it.

Say where you put something; ask where something is. The search box answers with the whole path — Garage › Shelf 1 › Blue box — with a mouse and keyboard or with your thumb.

Boxes move too

“Moved the red cables box from the storage room to the guest-room wardrobe” moves the box and everything in it. Every change lands in a history, and any of them can be undone.

Private on your own computer

The Windows edition keeps an encrypted database behind a password and never talks to Costia’s servers. Bring your own AI key — or a model running on the same machine.

Inside the app

  • Describe a room — “the kitchen has three cupboards and a pantry” — and it is filled in and drawn
  • Say what you moved in your own words, and it files it
  • Search by meaning: “something to charge the phone” finds the USB-C charger
  • Gemini on Android and Siri on iPhone can record a change for you
  • Everything it changes goes into the history and can be undone
