This paper introduces SoftBoard, a web-based tool designed to facilitate the creation and evaluation of low-fidelity prototypes specifically for Minimum Viable Product (MVP) development. By integrating a multi-agent system powered by large language models, SoftBoard automates requirements elicitation, prototype generation, and usability evaluation, thereby reducing the need for extensive UX expertise among teams. The key finding highlights that this tool not only streamlines the prototyping process but also enhances alignment with user needs, addressing significant gaps in existing prototyping tools.
SoftBoard revolutionizes MVP development by automating prototype creation and usability evaluation, making UX expertise optional for teams.
User Experience (UX) is recognized as a critical factor for the success of digital products, particularly in software startups, environments marked by time constraints, limited resources, and low maturity in design practices. Building Minimum Viable Products (MVPs) through low-fidelity prototyping represents a well-established strategy for rapid validation cycles at reduced cost. A systematic literature mapping, however, revealed gaps in the ecosystem of available tools: a predominance of general-purpose solutions adapted for prototyping, the absence of integrated methodological guidance, and the incipient use of Artificial Intelligence in the design process. This paper presents SoftBoard, a web-based tool for the creation and evaluation of low-fidelity prototypes in the context of MVP development. The tool integrates a prototype editor, team-based project organization, and a multi-agent system based on large language models that supports requirements elicitation and refinement, automates prototype generation, and evaluates interface quality based on usability heuristics. This integration aims to reduce reliance on prior UX expertise, standardize the prototyping process, and support teams in building MVPs aligned with user needs. As future work, a feasibility study with software professionals is currently underway.
