Redraw has been named the winner of South Summit 2026 in Porto Alegre, in the Digital and Tech Solutions category.

‍

More than 2,000 companies from around the world entered. Of those, only 50 reached the finals, split across 5 categories. Redraw was among them, and took the prize.

What South Summit is

South Summit is one of the largest global platforms for connecting startups, investors and large companies. It was created in Madrid and is now a benchmark for innovation. The Brazilian edition took place from March 25 to 27, 2026, in Porto Alegre, Rio Grande do Sul.

‍

This edition gathered more than 23,000 attendees, around 3,000 startups and 130 investment funds. It is one of the largest business and innovation hubs in Latin America.

‍

The finalist startups went through a program of mentorships and masterclasses before pitching their solutions on the main stages to a panel of investors, executives and specialists from the global ecosystem.

What this award means for Redraw

For us, this was a chance to show how much Redraw has been innovating, not only in Brazil but worldwide. We stood alongside companies that are becoming global references in what they do. Being able to present our solution at that level was an honor.

‍

“Being selected for the South Summit Startup Competition final is important recognition of the problem we are solving and the potential of our technology. Standing on that stage connects us directly to investors, strategic partners and global innovation leaders,” says Alexandre Kuhn, co-founder of Redraw.

‍

Sérgio Santos, also a co-founder, adds:

‍

“South Summit is one of the biggest global showcases for fast-growing startups. Being among the 50 finalists confirms that we are building a solution with international scale potential and real market impact.”

Why Redraw stood out

Redraw is the largest AI rendering platform for architecture in Latin America, with over 200,000 registered users and more than 500,000 renders generated every month.

‍

The differentiator that caught attention at South Summit is simple: Redraw turns a screenshot of a 3D model into a photorealistic render in under 40 seconds. No expensive hardware, no complex setup, no prompt engineering. Everything in the browser.

‍

While traditional tools like V-Ray, Lumion and Enscape demand powerful machines and hours of work, Redraw solves the same problem in seconds and at a fraction of the cost. And unlike generic AI tools such as ChatGPT or ComfyUI, Redraw was trained specifically for architecture. It respects the original project without inventing geometry.

‍

That combination of speed, accessibility and precision is what put Redraw on the South Summit stage. And it is what is making architects, engineers and interior designers around the world move to AI-driven rendering.

‍

‍

What comes next

The recognition at South Summit 2026 reinforces Redraw’s positioning in the global innovation ecosystem. With international visibility and direct exposure to investors and strategic partners, expansion into the US, Canada and Europe is gaining traction.

‍

The focus stays the same: keep delivering the best AI rendering experience for the people who design.

Have you ever spent more than 20 minutes writing a detailed prompt, specifying lighting, texture, angle, style, materials, only to get back a generic result with no coherence to the actual project?

‍

That's the loop most architects fall into when they start using AI for renders. The “super prompt” promise is seductive: the more detail you describe, the better the AI understands. In practice, that's not what happens.

‍

Alexandre Kuhn, founder of Redraw, breaks down the technical reason behind this, and shows why the platform was designed to work in a completely different way.

‍

This article summarizes what is explained in depth in the video:

Why long prompts create more problems than they solve

Tools like ChatGPT Image and Nano Banana Pro (built on Gemini) work with a simple model: you describe, the AI generates. The more you detail, the more variables enter the process. It sounds logical, but that's exactly where the problem lives.

‍

Every AI image generation starts with what we call a “seed”: a random number that defines the starting point of the creative process. Two identical prompts with different seeds produce completely different images. In other words, you can spend an hour refining the perfect prompt and still get inconsistent results on every generation.

‍

The practical effect? Architects spend more time managing text than working on the project.

‍

‍

‍

How Redraw was designed to eliminate that frustration

Redraw starts from a different premise: architects shouldn't need to describe everything. The platform was built to understand the project context and deliver high-quality renders from direct, objective commands.

‍

A command like “render it realistically, indistinguishable from a real photo” is already enough to produce results other tools only deliver after multiple iterations and prompt tweaks.

‍

This isn't an accident, it's the result of a model trained specifically for architectural rendering, not a generic image generation model adapted to the task.

‍

What makes Redraw more efficient in practice:

• Smart lighting presets: instead of describing light in words, you choose from pre-defined options (golden morning, sunset, starry night) and apply with one click. Result: consistent and controlled on every generation.
• Direct element manipulation: add a fruit bowl, remove an object, adjust a texture, all done on the image itself, without rewriting the command from scratch.
• Processing speed: renders in under 30 seconds, enabling more iterations and faster decisions in your workflow.
• Short prompt, complete result: the model interprets architectural intent, not just typed words.

Redraw, ChatGPT Image and Nano Banana: what each one delivers in practice

In the video, Alexandre tests the three tools side by side, with simple prompts and detailed prompts. The comparison reveals differences that go far beyond visual quality:

‍

ChatGPT Image 1.5: requires extensive prompts to deliver architectural coherence. With simple commands, results are generic and rarely ready for professional presentation.

‍

Nano Banana Pro (Gemini): performs well for general images, but inserts logos in some cases, a critical issue for professional use. Also depends on long descriptions for architecture-specific results.

‍

Redraw: superior results with short prompts, direct control over lighting and project elements, no watermarks or unwanted logos. Built for the architect's workflow, not for generic use.

‍

‍

The difference isn't just visual. It's operational: the time invested to reach a usable result in Redraw is significantly lower than in any other tool tested.

‍

‍

Redraw goes beyond rendering

Rendering is the entry point, but Redraw runs as a complete AI ecosystem for architecture:

• Idea Generator: explore facade, style and layout variations from a base image of the project.
• Render from sketch: turn a hand drawing or floor plan into a photorealistic image, no 3D model required.
• Brush (AI Brush): select a specific area of the image and modify only that region, texture, material, color, without altering the rest.
• Text to Image: generate visual references for presentations from a written description.
• Image to Video: turn a static render into an animation with depth and movement.

‍

All in a single platform. No switching between tools, exports and separate accounts.

‍

‍

Professional rendering doesn't have to be complicated

The complexity of super prompts is not a sign of sophistication, it's a sign that the tool wasn't built for your work.

‍

Redraw was made for architects, engineers and designers who need reliable, fast results with real control over the process. If you haven't tried it yet, access starts free.

If you receive an email from any other domain claiming to be from Redraw, treat it as suspicious.

‍

‍

On-site chat

You can also reach Redraw via the side chat that appears on the official sites (redraw.pro, redraw.pro/en, redraw.pro/es). It runs on the same system, the conversation lands with the same support team.

‍

‍

Security notice

Redraw never asks for credit card data, passwords, or banking information through support channels, not via WhatsApp, not via email, not via chat. All payments happen exclusively inside the platform.

‍

If anyone reaches out asking for that data while claiming to be from Redraw, do not provide it. When in doubt, send a message through another channel listed above and confirm whether the contact is legitimate.
