With V4, Rayon becomes the only software interior designers need. Drafting, 3D, documentation, and collaboration come together in one connected workflow, with AI helping designers move faster from a first idea to a finished presentation.
This release brings an AI experience built for the profession: one that reduces repetitive work, accelerates production, and gives designers more room to explore their creative ideas. It also introduces 3D and makes projects more accessible beyond the studio, bringing Rayon closer to the full reality of an interior designer’s working day.
V4 is available today to the thousands of companies already using Rayon, and to every designer ready to discover a new way of working.
Built before AI, with AI in mind
When we started building Rayon five years ago, we anticipated that AI would change how designers turn their creativity and intuition into drawings, spaces, and presentations. We saw an opportunity to make that translation easier, giving designers more time to develop their ideas and reducing the effort required to bring them to life.
Our first task was to build the canvas: a place where interior designers could express, develop, and communicate their ideas. That meant bringing the essential parts of their work into a shared environment, from the first lines of a floor plan to the pages used to present a project.
We built those foundations with AI in mind. We chose to work online and structured project data so that, over time, an AI agent could understand and contribute to the work taking shape on the canvas.
Over the past six months, we have focused on bringing that next layer into Rayon. With V4, designers can ask AI to help develop a drawing, explore layout options, furnish a plan, or prepare a presentation. They can delegate tedious, repetitive tasks while retaining control over the creative decisions that define a project.
What AI for interior design should be
For AI to be useful to interior designers, it needs to work where design happens. It needs access to the drawing, an understanding of the objects within it, and the ability to contribute directly to the project.
That is why Rayon’s AI agent lives close to the canvas. Designers can move a project forward through successive prompts, reviewing and directing the work at each step. An imported PDF can become an editable drawing. A plan can be zoned, furnished, and styled. Project information can become a schedule or a presentation.
The value comes from working in context. Drawings, objects, and project information give the agent a basis for its contributions, while the designer’s instructions guide what happens next. This makes AI part of the ongoing design process, available as ideas evolve.
That same principle extends beyond the canvas. Designers increasingly use tools such as ChatGPT and Claude to organize information, plan their work, and manage projects. Rayon should connect naturally with that wider ecosystem, allowing the information inside a project to support the rest of the workflow.
Our vision for AI is therefore both embedded and connected: able to contribute directly within Rayon, and open to the tools designers use around it. Less manual transfer, less repeated effort, and more continuity across the working day.
A long-awaited addition: 3D
Designers think in three dimensions. You told us that you needed to design that way in Rayon, too.
V4 introduces a 3D canvas alongside the existing model and paper canvases. It gives designers a way to develop spaces in three dimensions while keeping their 2D drawings and 3D models connected. The aim is simple: let a project evolve without requiring designers to do the same work twice.
We have approached 3D with the same focus on accessibility that shaped Rayon’s drawing experience. Modeling should feel intuitive and allow designers to explore a space at the level of detail the project needs. Moving into 3D should help develop an idea without adding unnecessary complexity to the process.
AI is part of that experience as well. Designers can generate 3D blocks and turn 2D floor plans into their 3D counterparts, reducing the work needed to move from a drawing to a spatial model.
Throughout, 3D remains a natural extension of Rayon. Designers can move between model, paper, and 3D canvases as they develop, document, and present a project, keeping each part of the workflow within the same connected space.
Built for the reality of the job
An interior designer’s working day extends well beyond a laptop. It moves between the studio, client meetings, supplier visits, and the job site. Project information needs to remain useful throughout that day.
With mobile support, designers can open Rayon projects on a phone or tablet to browse a plan, inspect details, and take measurements. When something needs attention, they can leave a comment in the context of the drawing, keeping the discussion connected to the place or detail it concerns.
Presentations also become a space for conversation. Clients can explore the design and leave comments, making it easier to collect feedback alongside the ideas being discussed. Teams can return to that feedback with the project in front of them.
Together, these additions bring Rayon closer to the everyday practice of interior design. From developing a layout at the studio to reviewing a detail on site, V4 keeps the work accessible wherever designers need to review, discuss, or make decisions.
Looking ahead to 2027
V4 marks the start of our next chapter. As we enter 2027, we want to accelerate: refine and bring 3D and AI out of beta, deepen what designers can accomplish in Rayon, and grow our community.
Our ambition is to make Rayon the single best design experience for the 90% of projects built around the world: the homes, workplaces, shops, and everyday spaces that shape how we live. We want to give the designers behind those projects everything they need to produce their best work, with less effort and more creative freedom.
