Studies present a single yes/no question to participants on cards which can contain a title, image, description, and price which can be varied to explore their effects. Select up to 40 total question attributes and participant demographics to identify features with real predictive importance for positive responses. Only participants with predefined characteristics are permitted to participate, ensuring that the study aligns with the target audience. Via the Linesol mobile app, participants answer questions (min. 10 seconds) receiving $0.05 per response ($18 per hour), fostering high quality data for actionable insights.
Define a yes/no question like 'Would you buy this product?' and enhance it with question card features such as Titles, Images, Descriptions, and Prices. This approach enables the exploration of how different design elements (such as various images showing different designs) impact the likelihood of positive responses. Each participant responds to one specific configuration, and is collected along with their anonymized user features for analysis.




Select from a catalogue of user feature categories, such as age, purchasing behavior, or environmental concern. Existing categories can be browsed alongside live demographic summaries of the participant base, helping you understand how each feature is represented before including it in a study. For each category, a set of categorical features can be selected for analysis. These selections define the participant demographic for the study, ensuring that only users with compatible characteristics are eligible to participate. If a relevant feature is not available in the catalogue, new user features can be submitted as category, feature pairs or as composite (latent) variables. By incorporating multiple user features, the study ranks these characteristics (along with question card features) to understand how they influence the likelihood of a positive response to the question.
Data Analysis
Unlock insights through a fully automated, machine-learning data analysis pipeline that ranks the features most strongly associated with a positive response, grouped by their net positive or negative effect. The analysis also includes price optimization and recommendations for improving future studies. After a study completes, the results include the full raw dataset (CSV), structured study results (CSV), and a detailed analytical report (PDF). This provides immediate insights while allowing full transparency for independent analysis. Live participant demographics, study launches, and results are accessible via the dashboard and the API.
