Minds operates on a sophisticated synthetic market research framework designed to deliver high-fidelity consumer insights without the logistical friction of traditional human panels. The platform allows users to construct highly specific target audiences by building individual AI agents called Minds, which represent validated consumer personas. These individual personas are then assembled into larger, representative panels that simulate the exact demographic, behavioral, and psychographic characteristics of a target audience. To ensure that these simulations are accurate and realistic, the audiences are anchored in empirical data. This includes customer relationship management data, prior market surveys, classic consumer studies, and robust demographic anchors. By grounding the AI agents in real-world data points, Minds prevents the generic or hallucinated responses often associated with standard large language models, ensuring that every simulated panelist behaves like a real person with specific constraints, preferences, and biases.
Once a synthetic panel is assembled, users can interact with it in a variety of ways to test business hypotheses and marketing strategies. The platform is built to run comprehensive concept tests, message testing, pricing elasticity studies, packaging evaluations, and brand positioning analyses. Users simply input their questions, upload creative assets, or present different product scenarios to the panel. The simulation engine then processes these inputs across the diverse personas within the panel. In under an hour, Minds delivers a dual-layered output that combines quantitative data with deep qualitative insights. Users receive statistical distributions, percentage splits, and numerical rankings that show how the audience as a whole reacts, alongside interview-style qualitative artifacts. These qualitative outputs include detailed, conversational feedback from individual personas, explaining the underlying motivations, anxieties, and decision-making processes behind their quantitative choices. This rapid turnaround allows research teams to iterate on ideas in real time, transforming a process that typically takes weeks into a fast, interactive session.
Validation and data integrity form the core of the Minds methodology. To build trust with enterprise researchers, the platform continuously benchmarks its simulated outputs against real human panel answers and official reference sources. These reference sources include highly respected national and international statistics agencies, such as the United States Census Bureau, the Bureau of Economic Analysis, Eurostat, and various national statistics offices. Through this continuous validation pipeline, Minds achieves an average of 85 to 95 percent agreement with traditional human panels, providing researchers with a reliable, audit-ready alternative to costly physical surveys. Furthermore, the platform is designed with a strict focus on security and ease of use. It runs entirely in the browser with no complex setup or infrastructure requirements. To align with global data protection standards, Minds is hosted on secure servers within the European Union and processes absolutely no personal data, ensuring complete compliance with modern privacy regulations while delivering rapid, actionable insights.
Semilattice approach is built on the concept of user simulation for AI-native product teams, positioning itself as a human world simulation platform. Rather than focusing strictly on traditional market research surveys, Semilattice is designed to help software developers, product managers, and designers understand how real users will interact with digital products, user interfaces, and feature updates. The platform aims to bridge the speed gap in modern software development, where engineering teams can build and ship features in a single day, but waiting for real-world user feedback or A/B test results still takes weeks. To use Semilattice, a product team describes a decision by dropping in a live product URL or uploading design mocks. They can then specify whether they are testing a live, deployed product or exploring an early-stage concept that does not exist yet, allowing them to gather signal before writing any code or launching a cold-start initiative in a new market segment.
At the heart of the Semilattice platform are its user models, which simulate human behavior and decision-making. These user models are constructed using real survey data and qualitative sources, capturing the attitudes, anxieties, and likely reactions of specific target segments. Users can select from a variety of pre-built user models or collaborate with the Semilattice team to build custom, private user models using their own proprietary data, customer surveys, and qualitative research. Once the user models are selected, Semilattice runs simulations where these virtual users interact with the product. Unlike simple static surveys, these simulated users can actually navigate through digital prototypes, simulating real-world behaviors such as clicks, hesitations, navigation paths, and drop-offs. This interactive simulation provides product teams with actionable data on conversion flow optimization, usability bottlenecks, and UX comprehension, showing exactly where virtual users get confused or lose interest.
A distinguishing feature of Semilattice is its deep integration into the developer ecosystem. Semilattice treats user insights as a form of development infrastructure, allowing teams to query user behavior in a manner similar to making database queries. This is achieved through its Model Context Protocol server, which connects Semilattice directly to popular AI coding tools and development environments, including Claude, Cursor, VS Code, Gemini CLI, and ChatGPT. By using this protocol, software engineers and autonomous coding agents can run user simulations directly from their terminal or code editor, testing code changes and feature concepts before they are even committed to a repository. Developed by Semilattice Ltd, an early-stage startup based in England, the platform is currently being built in public. To encourage adoption and gather feedback from the developer community, Semilattice is currently free to use, requiring no credit cards or formal contracts, making it highly accessible for teams looking to experiment with agent-driven user testing.
Minds is the ideal choice for marketing, insights, product, and innovation teams who require highly validated, statistically sound market research to guide strategic business decisions. If your team needs to run rigorous concept tests, evaluate pricing elasticity, conduct message testing, or analyze brand positioning, Minds provides the structured methodology and empirical backing required for high-stakes decisions. The platform is specifically engineered to replace or augment traditional human panels with synthetic audiences that are validated against official reference sources like Eurostat and the United States Census Bureau. Achieving an average of 85 to 95 percent agreement with real human surveys, Minds offers an audit-ready solution that gives executives, stakeholders, and research directors the confidence to act on synthetic data without sacrificing statistical rigor.
Additionally, Minds is the superior option for organizations that prioritize rapid, browser-based deployment, predictable commercial pricing, and strict data privacy compliance. Since Minds runs entirely in the browser with no technical setup or infrastructure to manage, non-technical team members can begin running complex research studies immediately. With transparent subscription tiers, including a Free plan, an Individual plan at 39 EUR per month, and a Team plan at 79 EUR per seat per month (with a 2-seat minimum), Minds fits easily into standard department budgets. Furthermore, because the platform is hosted on secure European Union servers and processes no personal data, it satisfies the stringent compliance and security requirements of modern enterprise organizations, making it a safe, reliable, and highly scalable research partner.
