Qlarr recently added AI validation as another layer to its survey validation system to catch quality issues harder to express as predefined rules.

Qlarr is an open-source research platform built to remove friction from research workflows. Most research tools handle simple surveys well. They break down when research gets serious. When surveys need complex logic, data needs to be collected in remote environments without internet, or when teams need clean, defensible data without spending hours on cleanup. Qlarr solves that. Design logic-heavy surveys without developer dependency, collect data anywhere without connectivity, validate responses at the point of collection, and own your data, your infrastructure, and your workflow completely. Built for market research agencies, field research teams, NGOs, and academic institutions running real research that demands reliability and control. Open-source platform. GDPR-compliant cloud hosting. No restrictions or vendor lock-in.
