Every PickFu response comes from a verified consumer — a real, identity-verified person who answers under a strict NDA. Respondents are sourced from enterprise-grade research panels (the same professional panels large companies use for consumer research) and quality-checked through a multi-stage AI and human review process. How PickFu keeps response quality high: a verified respondent gives an honest answer with a required written explanation, which passes multi-stage AI and human review; low-quality responses are filtered out (including ones you flag), leaving trusted results.

​
Where respondents come from

  • Enterprise-grade panel partners — established consumer-research panels, not an open or self-serve crowd.
  • 15 countries, each answering in their native language:
    • English: United States, Canada, United Kingdom, Australia, South Africa
    • Europe: France, Germany, Italy, Spain, Poland, Sweden
    • Americas: Brazil, Mexico
    • Asia-Pacific: Japan, Korea
  • Questions auto-translate into the respondent’s language, and their answers translate back into yours.

​
How PickFu keeps quality high

  • Identity verification — panel partners verify each respondent’s identity and demographics at signup.
  • Multi-stage filtering — a mix of AI and human curation reviews responses for quality.
  • A required “why” — every respondent must type a written explanation for their choice before they can submit, which filters out low-effort answers by design (see how surveys work).
  • Ongoing enforcement — respondents who consistently provide low-quality feedback are removed from the panel, and regular quality assessments run across all 15 countries.

Flag a low-quality response

If a specific response still looks low-effort or off-topic, flag it. Marking a response not helpful flags it for review, feeds PickFu’s panel-quality enforcement, and may auto-reject the response. You can do this programmatically:
Ask your AI assistant to rate the response — it uses the rate_response tool:
“Rate that last response as not helpful — it’s off-topic.”
Flagging is currently available through the MCP server and REST API. A response with no associated respondent can’t be flagged.Per-survey flag cap. How many not_helpful flags you can apply to a single survey depends on your plan:
  • PickFu+ and Enterprise subscribers — unlimited. Free trials of PickFu+ are treated as free accounts.
  • Free and pay-as-you-go accounts — capped at 10% of the survey’s sample size, rounded up (minimum 1). For example: 15 responses → 2 flags, 100 → 10, 1,000 → 100.
Removing a flag (DELETE /v1/responses/{id}/rate) frees a slot back up, so you can re-flag other responses within the same cap.
