SoftBoard: A Multi-Agent Tool for the Creation and Evaluation of Low-Fidelity Prototypes
This paper introduces SoftBoard, a web-based multi-agent tool designed to support software startups in creating and evaluating low-fidelity prototypes for Minimum Viable Products by integrating a prototype editor with AI-driven assistance for requirements elicitation, automated generation, and usability evaluation to reduce reliance on prior UX expertise.

Imagine you are trying to build a house, but you don't have a master architect, a huge budget, or even a clear blueprint. You just have a hammer, some wood, and a desperate need to get a roof over your head before the rain starts. This is exactly the situation many new software companies, known as "startups," find themselves in. They are racing against time with very few resources, trying to figure out what their customers actually want before they spend months building something nobody needs.
To solve this, experts use a trick called a "Minimum Viable Product" (MVP). Think of an MVP not as a finished house, but as a cardboard model of a house. It's rough, it's not pretty, but it proves the idea works. To make these cardboard models quickly, designers use "low-fidelity prototypes." These are like quick, messy sketches or wireframes—simple drawings that show where the doors and windows go without worrying about the paint color or the fancy doorknobs. The goal is to test the flow of the house (can you get from the kitchen to the bedroom?) without getting stuck on the details. However, many young teams struggle to make these sketches because they lack experience in design or don't have the right tools to guide them. They often end up guessing, which can lead to building the wrong house entirely.
This is where a new tool called SoftBoard comes in. The paper introduces SoftBoard as a digital playground designed to help these inexperienced teams build their "cardboard houses" (MVPs) without needing a professional architect on staff. It acts like a super-smart, patient tutor that guides you through the whole process. Instead of just giving you a blank canvas and saying, "Good luck," SoftBoard uses a team of artificial intelligence (AI) agents to help you figure out what you need to build, draw the rough plans for you, and then check your work to see if it makes sense.
The paper suggests that SoftBoard works by breaking the design process into three clear steps, much like a video game with levels. First, you talk to an AI chatbot that asks you questions to help you list exactly what your app needs to do. Second, once you have your list, the AI can automatically generate a rough draft of your app's screens and how they connect, saving you from drawing every single box by hand. Finally, another AI agent acts like a strict but helpful teacher, looking at your rough draft and giving it a score based on simple rules for making things easy to use. It tells you, "Hey, this button is hard to find," or "This path is confusing," and suggests how to fix it.
The authors found that while there are many tools for drawing apps, most are just blank canvases that require you to know exactly what you're doing. SoftBoard is different because it builds the method into the tool itself. It doesn't just let you draw; it tells you how to think about the problem. The paper shows that this approach can help teams who aren't design experts create better, more organized plans for their products. However, the authors are careful to note that this is still a new idea. They have built the tool and shown how it works in a test scenario, but they haven't yet tested it with real companies in the wild. They are currently running a study to see if real software teams find it useful. So, while SoftBoard looks like a promising new way to stop startups from building the wrong houses, it's still waiting for its final "real-world" inspection to see if it truly changes the game.
