Reliability is the default, not the upsell
Cronbach's alpha, item-total correlation, factor analysis, KMO, and Bartlett's test ship on every survey. No paid stats add-on, no export to SPSS, no consultant required.
Pick the right tool for the job
ReliCheck vs generic AI survey writers vs general survey platforms.
Three categories of tools solve three different problems. Generic AI survey writers help you draft items fast. General-purpose survey platforms collect responses at scale. ReliCheck is built for teams who have to defend the numbers afterward.
Pick ReliCheck when
- The buyer or stakeholder will ask "is the scale reliable?" and you need a credible answer in the report itself.
- You publish, present to a board, or submit for accreditation, and the methods section gets read.
- You want AI question review, plain-language reliability narration, and a four-tier "Can I use these results?" verdict in the same dashboard as alpha, KMO, and factor structure.
- You can buy the tool today on a credit card without a procurement cycle or a certified consultant.
- You work in research, evaluation, education, or HR where defensibility beats breadth.
Pick a generic AI survey writer when
- You need item drafts fast and reliability statistics will not be reported.
- The survey is one-time, low-stakes, and the output will not be challenged on methods.
- You plan to copy the items into another tool for distribution and analysis.
- You do not need item-total correlation, Cronbach's alpha, factor analysis, or response-quality flags.
- You will discard the survey infrastructure once the project ends.
Pick a general-purpose survey platform when
- You need maximum template breadth and the broadest set of marketing and CRM integrations.
- You operate at enterprise scale with regulatory requirements like HIPAA or FedRAMP.
- Survey panel access for paid respondents is core to your workflow.
- You distribute to non-research audiences where polish matters more than psychometric scrutiny.
- Existing organizational lock-in makes switching cost outweigh methodological gain.

What each category of tool actually ships
Capability comparison across the four buyer concerns that matter for research, evaluation, and HR survey work. No competitor names. The comparison stays evergreen.

Strengths
Where ReliCheck wins outright
Three places where the credibility frame produces a different kind of tool, not just a different feature set.
Plain English on every screen
Twenty-three AI tools translate the math into sentences a non-statistician can read. The numbers and the narration agree because they're computed from the same dataset, on the same page.
An answer to "is this credible enough?"
The "Can I use these results?" advisor returns a four-tier verdict tied to the Survey Strength Index. No other category of tool ships this surface today.
