Free Fraud & Inattention Checker

See exactly how much fraud and inattention is hiding in your sample. We classify every response and break down the specific reasons, whether you test your own suppliers or Rep Data sample.

What We Check

Two threats, one check

Our pre-survey fraud prevention and our in-survey data cleaning power every check, so you catch bad actors and disengaged respondents in the same pass.

Fraud

  • Duplicate respondents and devices
  • Bots and agentic automation
  • AI-written open-ends
  • VPN, proxy, and location mismatch
  • Survey farms and fraud rings
  • Suspicious device fingerprints

Inattention

  • Per-question speeding under normal totals
  • Contradictions across the full survey
  • Redundant patterns hidden in grids
  • Open-ends that repeat across respondents
  • AI-written open-ends that read as real
  • Unnatural typing cadence and keystroke gaps

Classified, Not Just Counted

Every response classified, with the reasons spelled out

We do not just hand you a fraud rate. Each respondent is classified as valid, inattentive, or fraudulent, and we break down the specific reasons behind every flag, so you can see exactly what failed and why.
