Sketch it.
Share it.
Step inside.

Arkio turns sketches, words and floor plans into real 3D designs, with an AI agent that models alongside you. Share a link to shape it together, then walk through it before anything is built.

Start anywhere

Start with whatever you have.

A napkin sketch, a few sentences, a photo, a floor plan, a room program or an existing model. Mix them in one conversation and the agent turns them into a 3D design you can build on.

Why Arkio

Simple enough for anyone. Powerful enough for architects.

Most design software makes you choose between easy and capable. Arkio is both: the agent handles the hard part, and you stay free to shape everything.

Simple enough for anyone

No installs. No training. No modeling.

Opens in your browserOn the laptop, tablet or phone you already have. Nothing to install.
Talk to it like a personDescribe what you want, or sketch it. The agent does all the modeling.
Share with one linkClients and colleagues join in a click, always on the latest version.
Nothing to breakEvery change can be undone, so you can explore freely.
Powerful enough for architects

Real geometry. Real numbers. Real handoff.

Measurable 3D, not picturesAreas, heights and layouts you can rely on, in every view.
Built for big modelsBring in Revit or Navisworks context and keep working at full speed.
Renders and films that matchAI renders and walkthrough videos made from the model itself.
Hand off without redrawingExport to Revit, Rhino and SketchUp when you're ready for detail.
Bring your own model

Already have a model? Bring it in.

Open your SketchUp, Revit, Rhino, Archicad or Navisworks model and review it together. The agent assists with design reviews too.

  • Ask the agent to find and highlight things, like every door or every room over 30 m²
  • Turn layers on and off, and add notes where they matter
  • Run checks on the model, like corridor widths or stair headroom
  • Optimize layouts and plans together with the agent, using movable objects from our Revit, Rhino, SketchUp and Archicad plugins
  • Try new options on top of your model, or ask for whole new versions of it

One tool, start to finish

Ideate, collaborate and experience, without switching tools.

Most tools do one of these. Arkio does all three on one live 3D model, so nothing gets lost between the idea, the conversation and the walkthrough.

01Sketch it

Explore ideas without modeling a thing.

Describe what you want and watch the agent build it in 3D, live. Ask for alternatives, compare them side by side and keep the one that works. Hands-on when you want, hands-off when you don't.

  • Options on demand, not just one answer
  • Follow the agent as it models, from any angle
  • Nothing is baked: every change can be undone
02Share it

One link. Everyone inside the same model.

Send a link and anyone can join from a browser: your team, your client, your consultants. Work on it together live or leave comments for later, with the agent on hand for everyone.

  • No installs, no file versions to chase
  • Live co-design and threaded comments
  • Hand off to Revit, Rhino or SketchUp when you're ready
03Step inside

Experience the unbuilt.

Walk through your design at human scale in the browser, on a computer, an iPad or a phone. Every view can become a render or a film that stays true to your model.

  • First-person walkthroughs on web and mobile
  • Live render, AI renders and AI video
  • VR version of Arkio 3.0 is coming soon
Live render, AI renders and AI video

Beautiful renders. Walkthrough films. Live as you design.

Every image and film comes from your real 3D model, so it shows the design you actually have, at its actual size. Most AI render tools start from a flat picture and fill in the gaps.

NEW IN 3.0

Live render: see the finished look while you work.

Switch it on and the view is rendered as you design, and as the agent designs. Change a window, a material or a whole wing and see how it will really look.

  • Updates as you and the agent edit
  • Any style, from photoreal to pencil
  • Grab a still or a film whenever you like

From a prompt to a finished render.

Made in Arkio 3.0.

Where Arkio fits

Where designs start.

Arkio is where ideas take shape and the big decisions get made, early, while changes are still cheap. When you're ready for detail, hand a clean 3D model to the tools your team already uses.

What will you design first?

Describe it in a sentence. The agent takes it from there.
