Rehearsals is an AI replicas simulation platform built for business decision-making. Its premise is to “rehearse” outcomes by simulating audience reactions before products, ads, pricing changes, or UX updates go live. The site describes it as an agentic simulation platform, with the core promise of delivering consumer preferences, reactions, and optimization suggestions within minutes.
Its capabilities are centered on market and product research. Users can ask questions such as how consumers might respond to a brand refresh, TikTok/Instagram ad performance, product pricing, a 2% price increase, an App redesign, or whether a Gen Z tagline works. The page showcases examples including ad creative comparisons, acceptance of Disney+ price increases, willingness to accept higher flight prices, and UX flow choices for an insurance website. It also claims an average accuracy of 91% in predicting consumer reactions and preferences, and says it predicts winning ads 30% better than frontier LLMs. The site also mentions that results are validated through real human interviews, which makes it feel more like a research tool than simply asking a general-purpose LLM to “guess what users think.”
Pricing information is limited. The page only offers a Book a Demo option, with no public plans, free trial, usage limits, or payment methods listed. On the integration side, the main page clearly shows a Slack use case: asking directly in a product launch channel what a specific cohort thinks about a redesign, then receiving sentiment analysis, reasons, recommendations, a full report, and cohort comparisons. It also supports Deck output, which is useful for presenting findings to management.
Its strengths are clear positioning and coverage of high-ROI scenarios such as pricing sensitivity, ad creative, product decisions, and UX research. The output includes not only conclusions, but also the reasoning behind them and actionable recommendations. The main limitation is the lack of public information: details about proprietary models, sample composition, industry boundaries, data privacy, Chinese-language support, and API availability are not fully disclosed. The official accuracy claims should be validated against the white paper and a company’s own historical data, rather than being assumed reliable across all markets.
Rehearsals is better suited to brand, growth, product, and user research teams with high experimentation costs, especially companies that need to quickly screen options before launching campaigns or products. It is less suitable for individual users or budget-sensitive small teams. The page does not provide evidence about access from China, so network availability, cross-border payments, and the ability to simulate Chinese audiences remain unknown. Alternatives include traditional user research, survey platforms, A/B testing, market research firms, or general-purpose LLM-assisted analysis.
