Mia Henderson

“It provides tons of great ideas, making it a fantastic source of inspiration for any project. The wide variety of interior and exterior designs goes beyond what you might expect, giving you a strong starting point to explore and customize your own style.”

Javi Rao

“Opening my first café, I had a tight budget and zero design experience—I just knew I wanted a ‘sunny, rustic-industrial’ vibe. I tried Sketchup first but got overwhelmed by the learning curve. DecAI was a revelation: I uploaded the empty storefront photo, selected ‘Café’ as the room type, and played with 5 styles until I found the right fit. I can just show the preview to tell the workers how to renovate different parts intuitively.”

Lena Choi

“Shows different color ideas and furniture choices in a photo of your own room…. Makes decorating and painting decisions so much easier.”

Carlos Mendez

“In seconds, I uploaded my bedroom, clicked on one of many selections of interior style, which was bohemian and hit select and the first draft came in just seconds and I asked if they could change out the plants on the nightstand to lamps and within seconds, they had the perfect lamps and lighted up the room, beautiful!!”
