What each tool is

RedrawFocus on architecture

An AI Hub specialized in architecture. Beyond its advanced rendering model, it brings several AIs together in one place and makes them easy to use: no complex prompts, no installation, 100% in the browser.

ChatGPTGeneralist

A pioneer in AI for text generation, recognized for precise answers. It also generates images from prompts, but with a generic focus: it was not developed for architecture or engineering.

Comparison by criterion

The three criteria that most impact your project.

We evaluate lighting, geometry and texturing, side by side.

Lighting

Who controls the light of the scene with precision and without rework.

RedrawWinner
Control
Built for architecture, it offers more than 30 lighting presets with visual examples to choose the exact option you want.
Ease of use
It does not require complex prompts, often no prompt at all. The interface is optimized for the creation flow, with use cases already defined.
Freedom to create
Good freedom, but it prioritizes the fidelity of the model, which requires well-defined lighting from the start.
ChatGPTGeneric
Control
Good lighting in the tests, but it falls short on control: it is rarely possible to be precise with prompts alone.
Ease of use
Because it is generic, it requires detailed prompts with technical knowledge. Without knowing how to ask, the results are imprecise.
Freedom to create
A more liberal choice. The caveat: when the requested light is very intense, it tends to alter the geometry of the project.

Lighting in Redraw is more precise and controllable, mainly because of its ease of use, with more than 30 organized presets. In ChatGPT, you need to master technical terms of photography and lighting to get good results.

Geometry

Who preserves the proportions, the structure and the camera angles of the project.

RedrawWinner
Control
It preserves the geometry of the project with precision, keeping even the original camera angles.
Ease of use
You do not even need to ask the AI to preserve the geometry, it already does that automatically.
Freedom to create
Because of its high commitment to fidelity, it allows few changes: great for preserving, limiting for structural changes.
ChatGPTGeneric
Control
It did not pass: it completely altered the geometry and even the camera angles. On the plus side: it keeps fidelity when reading text in the image.
Ease of use
It requires the user to repeatedly ask the AI to stay faithful to the geometry.
Freedom to create
Full freedom to alter the geometry during rendering, just by asking via prompt.

Redraw stands out in preserving geometry. When changes are needed, the user turns to other functions within the platform itself, including ChatGPT as an editing engine, all centralized in Redraw.

Texturing

Who recognizes and preserves materials such as woods, concretes and finishes.

RedrawWinner
Control
It preserves the originality of the textures and accurately recognizes materials such as woods, concretes and complex finishes.
Ease of use
It reads the elements of the scene better and interprets what is proposed more precisely, including complex finishes.
Freedom to create
More precise prompt-based editing, recognizing the elements well. The brush helps to delimit the exact area to change.
ChatGPTGeneric
Control
Difficulties controlling specific textures. In many tests it was necessary to send reference images.
Ease of use
Reasonably precise by prompt, but in some cases it required iterative conversation, generating rework.
Freedom to create
It has freedom, but it does not master the technical jargon of architecture: you need to send references constantly.

Redraw stands out in the fidelity of textures. It is worth noting that both have limits when the initial modeling is poor: a good optimization of the 3D model remains essential.

“I tested both tools together for a long time. Then I decided to stay on the free version of ChatGPT for occasional conversations, and to subscribe only to Redraw, because in it the uses are more targeted and I get better results. I switch to ChatGPT with just a few clicks and use it inside Redraw as a render engine. My workflow keeps improving with Redraw's updates.”

Frequently asked questions

What is the main difference between Redraw and ChatGPT for architecture?+
Redraw was developed exclusively for architecture, engineering and interior design, which means it understands the technical elements of a project: geometry, proportions, materials and lighting. ChatGPT, being a generalist AI, generates images that can be visually attractive, but it frequently alters the original geometry, modifies camera angles and does not preserve the fidelity of the project. To present renders of your own project to clients, Redraw is the more suitable technical choice.
Which one is easier to use for those who do not master prompts?+
Redraw. The platform was built to eliminate the need for complex prompts: in many cases the user does not even need to write anything. The interface offers visual presets for lighting, styles and ready-made finishes. ChatGPT, on the other hand, requires knowing how to describe technically what you want. Without knowing terms like color temperature, type of light or surface finish, the results tend to be generic.
What is the price difference between Redraw and ChatGPT for rendering?+
O Redraw oferece um plano gratuito com 10 credits, no card de crédito. Os planos pagos começam a partir de US$ 15/mês (Basic), com garantia de 7 dias. O ChatGPT Plus custa US$ 20/mês, mas para geração de imagens em volume e qualidade profissional o uso exige o plano Pro (US$ 200/mês). Considerando o custo-benefício para renderização de arquitetura, o Redraw entrega mais valor por menos.
Can ChatGPT render architectural projects with fidelity?+
Not consistently. In the tests, ChatGPT generated images with good visual quality, but it presented critical failures in preserving the original geometry: it altered proportions, changed camera angles and modified structural elements without being asked to. For renders that need to reflect the real project, this inconsistency represents a relevant technical risk in presentations to clients.
Can Redraw and ChatGPT be used together in the same workflow?+
Yes, and that is one of Redraw's great differentiators. The platform centralizes ChatGPT, Nano Banana, Kling and other AIs in a single environment. You can use Redraw's native rendering model to preserve the geometry of the project and then use ChatGPT within the platform itself for complementary adjustments. The result is a more efficient workflow, without switching between tools or opening multiple tabs.
Which tool best preserves the geometry of the original project?+
Redraw. This is one of the most critical criteria for architects and engineers, and it is exactly what Redraw was trained for. The platform automatically keeps the geometry of the project, without the user having to ask in the prompt. ChatGPT tends to modify the structure when applying styles, especially when there are complex changes in lighting or materials.
Do I need to know how to write prompts to use Redraw?+
No. Redraw was developed so that any architect or designer can use the platform without technical knowledge in AI or prompt engineering. The interface offers visual options for choosing style, lighting, materials and camera. For those who want to customize even further, the platform also accepts prompts, but that is optional.
Can I try Redraw for free before subscribing?+
Yes. Redraw offers 10 free credits with no credit card. You can test the render of real images of your project before subscribing to any plan. Paid plans come with a 7-day guarantee, with no bureaucracy.
Does Redraw work with SketchUp, Revit and Archicad?+
Yes. Redraw is compatible with the main 3D modeling software in the sector: SketchUp, Revit, Archicad and any other that allows you to export or capture images of the project. There is no need to install any plugin, just upload the image or screenshot of the model directly to the platform.
Which AI is more suitable for professional presentations to clients?+
Redraw. For presentations that need to reflect the real project, with correct proportions, proposed materials and appropriate lighting, the technical fidelity of Redraw is essential. ChatGPT can generate visually interesting renders, but without any guarantee of fidelity to the project.
Does Redraw completely replace ChatGPT for architects?+
It depends on the use. For rendering, visualization and presentation of projects, Redraw is vastly superior. But ChatGPT still has value as a text assistant: writing emails, reports, descriptive specifications or answering technical questions. The good news: you do not need to choose. Redraw already integrates ChatGPT into the platform.
