Over 41 million users across 170+ countries are using DecAI to evolve their home and design careers.

Sarah Collins, an exterior design studio designer

“I used to spend 2-3 days just drafting 2-3 exterior concepts for clients, and revisions would add another day of work. Since switching to DecAI, I can generate 5 polished 3D designs in 5 minutes, and clients can tweak colors/materials themselves without bugging me. My client satisfaction rate went up 40%, and I’ve taken on 3x more projects this year without burning out.”

Michael Turner, a senior real estate agent at Washington

“As a real estate agent, staging listings used to cost me hundreds per property. DecAI’s exterior cleanup and design tool lets me turn drab facades into eye-catching previews in 30 seconds. I listed a 1980s home last month with a DecAI-generated modern facade redesign, and it got 3x more showings and sold $20k over asking. Total game-changer for my listings.”

Emily Wong, a homeowner

“I wanted to renovate my backyard but had no clue where to start. DecAI’s garden design tool lets me upload a photo of my messy yard, pick a ‘cozy cottage’ style, and generate a layout with plants that actually grow in my climate. I tweaked the fire pit location a few times, then showed the design to my landscaper—he said it was more detailed than most professional plans he sees. Saved me thousands on a designer.”

Jason Miller, the owner of a Café

“Running a small café, I needed to refresh my storefront and interior on a tight budget. DecAI let me design both the exterior signage/color scheme and interior seating layout in one place—no need to hire separate exterior and interior designers. The material cost estimator even helped me stay under budget.”

Olivia Bennett, a general contractor

“I’m a general contractor, not a designer. Before DecAI, explaining design ideas to clients was a nightmare—they’d misinterpret my sketches and get frustrated. Now I upload their home photo, generate 2-3 styles with DecAI on the spot, and they can see exactly what the finished exterior will look like. Revisions are fast, and I’ve cut down on change orders by 60% because expectations are clear from day one.”

Daniel Rodriguez, a home designer

“I initially tried DecAI just for quick inspiration, but it ended up becoming part of my early design workflow. For exterior concepts, it helps me explore directions fast and align with clients before moving into detailed drawings.”
