AI concept testing
Lewsearch can screen concepts with a synthetic panel: a short brief, a defined audience, and stated-preference questions on comprehension, objections, and choice. That is a screen, not a sales forecast. It is not validated conjoint, not price elasticity, and not a conversion prediction.
What you provide
A concept brief in plain language: the offer, the who, and the alternatives. An audience definition the panel can match (market, plus any demographic filter the product supports). And the questions you want asked. Suitable items: comprehension, confusion, objections, stated preference, and which concept they would pick.
Supported comparison designs
A single concept against a control description. Side-by-side choice among two to four concepts. Or a monadic read, one concept per cell, then a comparison of the cells. Message testing covers the creative form of the same job. None of those designs is a marketplace experiment.
Illustrative study plan
Hypothetical, not a customer result. A DTC brand has three packaging lines. It writes a 80-word brief for each, asks a national panel of 500: which is clearest, which they would buy, and what is confusing. The fourth-place line is dropped. The two remaining lines go to a cheap live split. That sequence is the product. The shares in this paragraph are invented for the shape of the plan.
After the screen
Keep finalists. Kill confused concepts. Do not ship a launch decision from synthetic stated preference alone. If you need a human holdout on an instrument you already ran, that is sample boosting, not this page.
| Method | What it returns | What it does not return |
|---|---|---|
| Lewsearch panel screen | Comprehension, objections, stated choice | Sales, conversion, elasticity |
| Human concept test | The same questions from recruited people | A legal sample unless designed as one |
| Live traffic | Clicks and conversion | Why people objected |
FAQ
- Can Lewsearch test product concepts?
- Yes, as a stated-preference screen. Write the concept, pick an audience, and ask comprehension, objection, and choice questions on a panel study. Message testing can carry the creative. Do not treat the shares as a sales forecast.
- Is this conjoint or a demand curve?
- No. Looping a concept across prices is still stated preference. It is not validated conjoint and not an elasticity estimate.
- What do I take to humans?
- The shortlist. If two concepts sit close, or the decision is spend, legal, or a launch gate, field the finalists with humans or live traffic.
- Where do I run it?
- Panel studies for structured questions. Message testing for creative. The research API on Pro and Enterprise for repeated screens. Concierge if you want the instrument written for you.
