What You Can Test
Each study tests a single direct decision while varying question-card features such as title, image, description, and price. Participant variables can be defined alongside those card variations, allowing Linesol to estimate which inputs are associated with higher or lower positive response rates under controlled conditions. The result is a streamlined way to test concepts, pricing, messaging, and audience fit before committing larger production or marketing resources.
Question Card Features
Define a binary decision such as 'Would you buy this product?' and test structured variations across titles, images, descriptions, and prices. Each participant sees one specific configuration, creating cleaner behavioral data that can be compared across controlled permutations to identify which features are associated with higher or lower positive response rates.
User Features
Select user feature categories spanning demographics, preferences, and behaviors. For each category, select the attributes you want analyzed and use them to define the participant base for the study (with smart participant filtering for balance). We also provide a live demographic summary to help estimate the time to receive responses. The feature catalogue expands over time to capture the most informative and actionable variables predicting decision-making. For naming standards and governance rules see the User Features Guidelines.
What You Learn
Data Analysis
Each completed study is processed through an automated ML analysis pipeline, so once responses are in, feature importance, segment-level differences, pricing signals, and follow-up study recommendations are returned without manual synthesis. Outputs include raw data, structured results, and a detailed analytical report so teams can review both the recommendation layer and the underlying evidence. Pricing is usage-based, so teams can run studies without subscriptions or fixed platform commitments. These outputs can then be reviewed in the dashboard or exported through the API.
Feature Effects
- See which card-level variables such as title, image, description, and price are associated with higher or lower positive response rates.
Pricing Signals
- Estimate how positive response rates differ across the price points you tested to identify an evidence-based pricing direction before launch.
Segment Insights
- Understand which participant attributes are associated with stronger or weaker response rates, supporting clearer targeting and positioning decisions.
Suggested Improvements
- Review multicollinearity results and apply dimensionality-reduction techniques to refine feature selection, improving model stability, interpretability, and predictive accuracy.
Case Studies
These case studies are the clearest current proof of what Linesol produces. Each one turns a pre-launch decision into a structured experiment and shows how product concepts, pricing, messaging, visuals, and audience variables can be tested before rollout. The result is a clearer path to interpretable evidence when teams need to reduce uncertainty before committing budget, creative, or production resources.

How We Support Advanced Teams
Linesol combines a clear study structure, automated analysis, and a deeper path for teams that want to inspect the underlying evidence more closely.
Controlled Research
Each study is a structured binary experiment where question-card variables such as title, image, description, and price can be varied alongside participant variables. In practice, that gives teams one workflow that can support familiar research patterns such as A/B monadic testing, segmentation, price-sensitivity testing, feature-importance analysis, and rapid pre-launch concept checks.
Automated Analysis
Once responses are in, Linesol returns interpretable outputs through an automated ML analysis pipeline, including feature effects, pricing signals, segment differences, and follow-up study recommendations. The aim is not just to collect responses, but to turn them into decision-ready evidence quickly.
Advanced Teams
For teams that want a deeper analytical path, the workflow also exposes raw exports, report diagnostics, and full API execution across reviewing demographics, launching studies, and retrieving results. Composite-variable development can then be pursued externally when overlapping predictors should be consolidated into stronger higher-level variables.
