Design your space. Just ask.

Your home.
Your imagination.
Just ask.

Connect your favorite AI assistant and design your space through conversation. Create rooms, arrange furniture, and explore every idea in interactive 3D.

Works with Claude, ChatGPT, Cursor and any MCP-capable agent.

Agent → TalkToRoom

Live 3D — drag to orbit, scroll to zoom. Built from real MCP operations.

How it works

Three steps. No software to learn.

  1. 01

    Connect your AI.

    Add TalkToRoom to Claude, ChatGPT or Cursor with one MCP link. Your assistant gains tools to build and edit real spatial scenes — no new chatbot to learn.

  2. 02

    Describe your space.

    “An open living room and kitchen, two bedrooms, one bathroom — modern Scandinavian.” Your assistant creates rooms, doors, windows, materials and furniture.

  3. 03

    Watch it come to life.

    Open the link and walk through your design in 3D. Every change appears in about a second. Save versions, compare ideas, and keep iterating by talking.

A conversation, not a CAD tool

Say it the way you’d tell a designer.

Your assistant translates intent into precise geometry — meters, polygons, collisions, clearances — and TalkToRoom keeps every result valid.

Make the living room cozier. Replace the sofa with a sectional, add a large rug, and move the dining table toward the kitchen.

Done — sectional against the north wall, 2.4 × 3.4 m rug underneath, dining table shifted 1.1 m east. No collisions; 0.9 m of walkway kept to the balcony door. Saved as V2.

Compare it with the original.

Added: sectional, rug. Removed: 3-seat sofa. Moved: dining table. Open the comparison →

Real geometry

Rooms are true polygons. Walls, doors and windows are structured data in meters. Furniture has real dimensions — not a picture of a room.

Always valid

Collisions, blocked doors, furniture through walls and tight walkways are caught on the server and reported back to your assistant.

Every idea, kept

Immutable versions you can name, compare side-by-side, restore and branch. Try a bold option without losing the original.

Bring your floor plan

Upload a PNG, JPEG or PDF. Your assistant reads it, sets the scale and traces rooms into 3D — verified against an overlay.

Walk through it

Orbit, top-down plan, isometric, and first-person walkthrough with smooth transitions.

Built for agents

42 MCP tools, resources and a transactional batch API, so a whole apartment takes one round trip.

Connect your AI

One link. Any agent.

TalkToRoom speaks the Model Context Protocol over Streamable HTTP at /mcp. Add the server URL to your assistant, sign in, and approve access to your projects.
