Introducing Deco: AI interior designer
Introducing Deco: AI interior designer
Deco on iOS is an AI interior design app that allows users to upload photos of their interior and redesign it using generative AI tools. It is live on the app store and available in the US and Canada.
My work: I was the sole designer working on this project. I worked on everything from user research, to conceptualization ,wireframing and prototyping, all the way up until user testing and releasing the app on iOS

First, I tried to draw out 3d environment where users can drag and drop furniture and move it around on different axes to place it however they liked.
We did not end up going with this approach due to:Learning curve
Time and technical constraints

Second, I sketched out a flow where users could upload a picture and use and Generative AI chat interface to make modifications like - "Add a painting on the wall."
This was a good approach:Easy to learn
First time mover advantage
This is the flow used that was finalized for the MVP

I felt the need for users to draw inspiration from somewhere and take it a step further by letting them edit it exactly to their preferences and tastes.
So a user could browse images > Select an image > Modify it using GenAI > Save and share it
In the interest of time, this feature was deprioritized and not included for the MVP launch.


The MVP prioritized intuitive GenAI features to ensure ease of use and maximize user value.

After users create their dream design, the app automatically tags furniture in the image and shows you links to similar products across the web.
A lot of these are affiliate links, so if the user makes a purchase, Deco gets a share too!

This was the first time I got the chance to be involved in a project right from the Idea stage to shipping an MVP. I got to experience the full product life cycle and improvise whenever necessary.

Designing around tech constraints
There were a lot of times tech constraints posed an obstacle to ship some design features/ elements. I had to come up with create ways to circumvent this and still deliver value to the user.
