## How Minds actually works

Minds operates as a dedicated synthetic market research platform built to democratize high-fidelity audience insights for marketing, insights, product, and innovation teams. The platform allows users to build highly specific AI personas, known as Minds, and assemble them into customized panels that mirror a precise target demographic. Instead of waiting weeks to recruit human participants, coordinate schedules, and synthesize survey responses, users can deploy these panels to run comprehensive concept, message, pricing, packaging, and positioning tests. The entire simulation process is completed in under an hour, yielding both structured quantitative data and rich, interview-style qualitative artifacts that allow researchers to understand the underlying motivations behind every simulated response.

The core strength of Minds lies in its rigorous, multi-layered data anchoring and validation pipeline. Rather than relying on generic, ungrounded language model outputs, the synthetic audiences created within Minds are anchored in real-world data. This includes proprietary customer relationship management data, prior human surveys, and classic market studies, combined with precise demographic anchors. To ensure the reliability of every simulation, the platform continuously validates its outputs against real human panel answers and official reference databases. These reference sources include the US Census, the Bureau of Economic Analysis, Eurostat, and various national statistics agencies. By comparing synthetic responses directly with these authoritative benchmarks, Minds achieves an average agreement rate of 85 to 95 percent with traditional human panels, giving researchers the confidence to make high-stakes business decisions.

Accessibility and ease of deployment are central to the design of Minds. The platform requires no complex setup, developer resources, or technical infrastructure. It runs entirely within a standard web browser, allowing non-technical business users to configure research projects and analyze results through an intuitive graphical interface. Data privacy and compliance are treated as fundamental priorities, with all simulations hosted securely on EU servers. The platform processes no personal data, making it fully compliant with strict data protection regulations and suitable for enterprise environments with rigorous security standards. With highly accessible pricing including a free tier, a Premium plan at about 39 euros per month, and Team plans at about 79 euros per seat per month, Minds makes enterprise-grade market research instantly available to organizations of all sizes.

## How Semilattice actually works

Semilattice, founded in 2023 and headquartered in Harrow, United Kingdom, positions itself as a human world simulation platform. Developed by a team with extensive product and engineering experience at Google, Stripe, and Figma, the platform is designed primarily to help AI-native product teams, developers, and product managers simulate how real users interact with software, interfaces, and product decisions. Rather than focusing solely on traditional survey-based market research, Semilattice aims to predict user behavior at a granular, interactive level. It bridges the gap between static user feedback and dynamic product interaction, allowing teams to test early ideas, prototypes, and live software environments before committing valuable engineering resources to production.

To run a simulation, users begin by selecting an audience representation, known as a user model. Semilattice offers a library of over fifty pre-built user models drawn from real survey data and qualitative sources, such as consumer finance segments in the United Kingdom. Alternatively, organizations can collaborate directly with the Semilattice team to build custom, private user models using their own proprietary customer data, surveys, and qualitative inputs. Once a user model is selected, the user describes the product decision they are trying to make, uploads design mocks, or inputs a live website URL. The platform then generates realistic user tasks and success criteria, allowing the simulated users to interact with the material and return predicted response distributions alongside qualitative interpretations.

A defining feature of Semilattice is its capability for live user journey simulations. Instead of just answering static questions, simulated users can actively navigate live websites or prototypes. By inputting two different URLs, product teams can run comparative A/B tests to analyze completion rates, page flow, time on task, and specific friction points. This interactive simulation is highly integrated into developer workflows. Semilattice provides a Model Context Protocol server, a Python SDK, a Node.js SDK, and an API, enabling developers to connect the platform directly to AI coding assistants like Claude, Cursor, ChatGPT, and Gemini CLI. This allows software engineers to programmatically query user models mid-workflow, testing copy, pricing structures, or feature concepts directly from their command-line interface or code editor.

## When to choose Minds

Minds is the optimal choice when your primary objective is to conduct rigorously validated market research, concept testing, and positioning studies with high statistical confidence. If you are a marketer, brand manager, insights professional, or product innovator, you need to know that your synthetic audience accurately reflects the real world.
