Arka for Blender
Draw walls in Blender, and Arka furnishes the rooms: it places the furniture you pick, or lets the AI pick it from the room’s type and size. Every install comes with a free trial.

Install it in five steps
-
Download the zip
Keep it zipped: Blender installs the zip itself.

Install it in Blender
Drag the zip into Blender’s window and confirm Install. Or open Edit › Preferences › Get Extensions, click ⌄ at the top right, choose Install from Disk… and pick the zip.

In the 3D Viewport, press N and pick the Arka tab in the sidebar.

Draw, then furnish
Draw walls: a closed loop becomes a room. Choose the room’s type and click Auto furnish, and the AI picks the furniture and places it. Or add pieces to the room’s list yourself and click Furnish.
Or let Arka design the house: in the Generating panel pick an outline as the Boundary and click Generate. The rooms are laid out in a few seconds, around the outline’s entrance and windows, and ◀ ▶ shows other layouts.

Subscription $10/month

What does the add-on send?
With each furnish: the room’s outline (its wall corners), its doors and windows, the furniture list and your Auto furnish notes; with Generate: the boundary’s outline and its doors and windows and the rooms you picked; with every request, the add-on and Blender version, your platform, a random token that identifies the install and, once activated, your license key. With the Arka assistant: your messages, a short summary of the scene (the rooms, their types and sizes, the storeys, the roof, the materials) and, when it looks, a picture of the viewport, sent to Anthropic: straight from Blender with your own Anthropic key, or through Arka on Arka’s AI. Nothing else from your scene or your files.
