The biggest question is which AI tool to use. Some are better for creating concepts from scratch, while others are better for editing and improving existing images.
In this guide, we'll walk through a simple AI workflow and look at three tools that are worth checking out: Krea, Adobe Firefly, and Midjourney.
Step 1: Decide What You Want to Create
Before opening any AI tool, it's worth spending a minute thinking about the result you're after.
Are you creating an exterior render? An interior? A modern house? A commercial building?
It also helps to think about the lighting, materials, camera angle, and overall style you want. The clearer your prompt is, the better the AI usually performs.
If you already have a sketch or reference image, even better. Most AI tools now let you upload one to guide the final result.
Step 2: Generate Your Render
Once you know what you're creating, it's time to start experimenting. Here are three of the best tools that stand out for different reasons.
1. Krea
When you're working on architectural concepts, the first render is rarely the final one. You usually want to try different materials, lighting, angles, or even completely different styles before deciding which direction to take.
That's where Krea AI works really well.
You can start with a simple prompt, upload a sketch or reference image, or combine both. If the first result isn't quite right, it's easy to generate new versions, edit specific parts of the image, or improve the quality without starting again.
Another advantage is that everything happens in one place. Instead of jumping between different AI tools, you can generate, edit, upscale, and even animate your renders from the same workspace.
Where it works best
- Early design concepts
- Exterior and interior visualizations
- Exploring different materials and lighting
- Turning sketches into presentation-ready renders
What surprised us
What surprised us most was how complete the workflow feels. Instead of using one tool to generate images and another to edit or improve them, Krea lets you do almost everything in one place, which makes the whole process much smoother.
Best for: Architects and designers who want one tool to take a project from the first concept to a polished render.
2. Adobe Firefly
Firefly feels less like a concept generator and more like a finishing tool.
Once you already have a render, it's useful for making quick changes without opening a full 3D scene again. Need a different floor material? Want to extend the background or remove a distracting object? Those kinds of edits are where Firefly really shines.
If you're already working in Photoshop, it fits naturally into your workflow because most of the AI tools are built directly into the editor.
Where it works best
- Client revisions
- Material changes
- Presentation images
- Quick image edits
What surprised us
The biggest surprise was how much time it can save. Small changes that might normally mean going back to your rendering software can often be done in just a few clicks inside Photoshop.
Best for: Architects and designers who already use Adobe Creative Cloud and want to speed up image editing.
3. Midjourney
Sometimes you don't need a finished render - you just need ideas.
That's probably Midjourney's biggest strength.
It's a great tool for experimenting with different architectural styles before you've committed to a design. Whether you're looking at modern villas, brutalist buildings, Scandinavian interiors, or futuristic concepts, it can generate dozens of different directions in a short amount of time.
Many architects use it at the very beginning of a project to create mood boards or help clients visualize different possibilities.
Where it works best
- Mood boards
- Early design concepts
- Style exploration
- Client inspiration
What surprised us
We were impressed by how creative the results can be. Even fairly simple prompts often produce striking architectural concepts that are useful for brainstorming or presenting early ideas to clients.
Best for: Architects and designers looking for inspiration before moving into detailed design.
Step 3: Refine and Export Your Render
Once you've generated a render you like, spend a little time refining it before sharing it with a client or your team.
You might want to adjust the lighting, change materials, remove small distractions, or create a few different versions to compare. Most AI tools make it easy to keep improving an image without starting from scratch.
If you're happy with the final result, export it in the resolution you need for presentations, mood boards, or project proposals.
Conclusion
AI has made it much easier to create architectural renders and explore new ideas. Instead of spending hours testing different concepts, you can quickly generate images, try different styles, and make changes as your design develops.
SEach of the tools in this guide has its own strengths. Krea is a great all-around option if you want to generate, edit, and improve your renders in one place. Adobe Firefly is a great fit if you already use Photoshop, while Midjourney is ideal for exploring creative ideas and putting together mood boards.
At the end of the day, the best tool depends on your workflow. The good news is that whichever one you choose, AI can help you work faster and spend more time focusing on the design itself.
