Simulacra: Automating Usability Testing

Traditional usability testing with human subjects is prohibitively expensive, slow, and resource-intensive, creating a major bottleneck for software development. Current AI-driven UI evaluation tools fail to solve this because they act as omniscient experts with full access to underlying code, entirely missing the genuine friction an average user experiences. Simulacra solves this by deploying a custom multi-agent architecture—a UI-Controller, an HCI Expert, and a vision-limited Persona Agent. By defining specific demographic attributes like digital fluency and visual acuity, teams can generate highly realistic user personas. The UI-Controller restricts the Persona Agent strictly to visual screenshots, effectively mimicking human cognitive limits. Meanwhile, the HCI Expert analyzes the persona's visual struggles against the actual DOM to provide actionable friction scores and per-page recommendations. Targeted at agile web development teams, SaaS startups, and product design agencies, Simulacra drastically reduces time-to-market. It allows teams to catch critical UI/UX flaws in minutes rather than weeks, ensuring a highly optimized product reaches the consumer.
