Share a link, then walk through it before anything is built." url: https://www.arkio.is/ --- [New: Arkio 3.0 is now on the web](https://www.arkio.is/whats-new/) # 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 designing](https://app.arkio.is) - Runs in your browser - No 3D skills needed - Works with Revit, Rhino, SketchUp, Archicad and Navisworks _Illustrations: the page shows one of three starting points on each visit, with what the agent made of it._ - A pencil sketch of a two-storey courtyard house with handwritten notes: 2 floors, courtyard, family house, about 200 m², timber on the garden side. Result: The Arkio web app, where the agent has turned the sketch into a 3D model: a 202 m² courtyard house over two floors, with Sara editing and Tom hosting in the same scene - Two reference photos taped down with handwritten notes: like this cantilever; timber, glass and a pool. Result: The Arkio web app, where the agent has turned the two photos into a 3D model: a 194 m² pool house with a 5 m cantilever, with Sara editing and Tom hosting in the same scene - A floor plan of a garden flat with handwritten notes (open this up, island?, big glass doors) and a style photo: warm, like this. Result: The Arkio web app, where the agent has remodelled the flat from the plan: an open kitchen with a 2.5 m island and glass doors to the garden, with Sara editing and Tom hosting in the same scene Trusted by architects, engineers and educators at KPF, Sweco, IMEG, BAM, American Structurepoint, CetraRuddy, SPINN Arkitekter, Davey + Smith Architects, TU Delft. 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. **A pencil sketch.** Snap a photo of the back of an envelope. Rough is fine. **A few sentences.** Describe the space the way you would to a friend. **Reference images.** Show the mood, materials or style you are after. **A floor plan.** Upload a drawing or a PDF and watch the rooms rise. **A space program.** Paste your area schedule. The agent does the stacking. **An existing model.** Bring in your Revit, Rhino, SketchUp, Archicad or Navisworks model for context. Works for a kitchen, a family house or a city block. 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 browser.** On the laptop, tablet or phone you already have. Nothing to install. **Talk to it like a person.** Describe what you want, or sketch it. The agent does all the modeling. **Share with one link.** Clients and colleagues join in a click, always on the latest version. **Nothing to break.** Every change can be undone, so you can explore freely. Powerful enough for architects ### Real geometry. Real numbers. Real handoff. **Measurable 3D, not pictures.** Areas, heights and layouts you can rely on, in every view. **Built for big models.** Bring in Revit or Navisworks context and keep working at full speed. **Renders and films that match.** AI renders and walkthrough videos made from the model itself. **Hand off without redrawing.** Export 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 [See how architects use Arkio](https://www.arkio.is/architects/) _Illustration: A Revit model brought into Arkio: the agent has hidden the furniture layer, flagged a corridor under 1.2 m wide and placed a timber study on the garden side to compare_ 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. 01 · Sketch 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 _Illustration: The agent offers three layouts for a 200 m² family house: a courtyard, an L-shape and a long house_ 02 · Share 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 _Illustration: A shared model with the architect, the client and the agent working in it at the same time_ 03 · Step 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 _Illustration: People walking through a design together at full scale, in walk mode_ 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. _Illustration: Live render of a modern villa with a pool that updates while the agent widens the upper-floor glazing, with the 3D model inset_ 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. The prompt A small timber cabin with a flat roof, a covered deck and big windows onto the garden. Now render it on a sunny summer afternoon, with people on the deck.

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. _Illustration: Chart: early on, the freedom to change a design is high and changes are cheap. Arkio works in that stretch, from the idea to concept and options, then hands off to Revit, Rhino and SketchUp_ **Bring in your models for context:** Revit, Rhino, SketchUp, Archicad, Navisworks **Hand off when you're ready for detail:** Revit, Rhino, SketchUp, OBJ, GLB Who it's for ## Made for everyone who shapes a space.

Describe it in a sentence. The agent takes it from there. Start designing: [open the Arkio web app](https://app.arkio.is/?prompt=A%20garden%20studio%20with%20a%20green%20roof) and describe your idea, for example “A garden studio with a green roof”. The design agent uses AI credits. More ideas to try: A 3-bedroom family house; Open up my kitchen; A primary school for 300 pupils; Massing for a mixed-use block. AI credits required · Runs in your browser · No 3D skills needed ![A finished design in colour among grey neighbours](https://www.arkio.is/_astro/film_4.D103mK7s.svg) --- Arkio: Arkio turns sketches, words and floor plans into real 3D designs with an AI agent.
