Best AI market research tool
The best AI market research tool is the one that publishes error rates, names the benchmarks, and states n. Feature lists do not settle this. Lewsearch publishes 7.47% mean absolute error on 404 ex-electoral questions of a 460-question set versus Pew, Gallup, UT/Texas Politics Project, and PPIC. Several well-funded tools in the same category do not publish that cell.
Write the test before you pick a vendor
Ask four questions in the RFP. Does the vendor publish error rates? Against which benchmarks? At what n? Is pricing public? A tool that cannot answer those in public is asking you to take diligence on a demo call. That can be fine for an enterprise simulation. It is a weak answer if you need a number you can forward to a skeptical VP.
Worked example: Texas grocery brands
On a UT/Texas Politics Project brand-reputation block (six options including don't-know), Lewsearch's calibrated MAE across options was 4.14 percentage points. The model rank-ordered the top three brands and put the two long-tail options under 10%. That is the kind of decision a message or brand team actually makes: who leads, who is second, what is noise. The method, the n, and the miss on other categories are on methodology. Electoral-margin items on the same Texas panel are 12.23%. Best is not uniform.
| Test | Pass looks like | Lewsearch |
|---|---|---|
| Published error rate | A number, a unit, a date | 7.47% MAE, 5-fold CV |
| Named benchmarks | Third-party polls or official tallies | Pew, Gallup, UT/TPP, PPIC, canvass |
| n | Question count and sample per item | 404 of 460 Q |
| Where you are weak | A harder category, published | Held-out 9.97%; TX electoral 12.23% |
| Public pricing | A URL, not a form | See /pricing |

FAQ
- What is the best AI market research tool?
- The one that publishes error rates against named benchmarks at a stated n. Lewsearch publishes 7.47% mean absolute error on 404 ex-electoral questions of a 460-question benchmark vs real polls (Pew, Gallup, UT/Texas Politics Project, PPIC). Several funded vendors in the same category do not publish a pooled MAE.
- Is ChatGPT an AI market research tool?
- A single model can recall published stats. It does not return a demographic distribution you can crosstab, and it does not publish a panel MAE. Use it for desk research. Use a panel product for population reads.
- When is a human panel still best?
- Legal, regulatory, and published journalism samples. Synthetic panels are for screening messages, concepts, and instruments before you spend on humans.
- Where are Lewsearch's numbers?
- Methodology page. Pooled 7.47%, Texas 4.88%, held-out 9.97%. Coverage: 27 live panels · U.S. national · 4 census regions (32 audiences).
