Research Defender Alternatives
Replace a person-only quality score with a dual-layer gate. AI Agents do not care about your score.
Other platforms score the respondent. Maxna scores the respondent and the response.
Device IDs, bots, VPNs, and duplicates are necessary. They are not enough. A real device can still paste ChatGPT into every open-end. Maxna's proprietary AI grades what people type - so sample integrity is both who they are and what they say.
Respondent quality
Where most tools stop
- Device fingerprinting and environment risk
- Bots, scripts, and click farms
- VPN / proxy and geo mismatch
- Duplicates and professional respondents
Response quality
Maxna's proprietary AI layer
- AI-written and synthetic open-ends
- Low-effort and copy-paste answers
- Cross-question consistency
- Open-end scoring before the complete is paid
A Research Defender alternative should not be a thinner respondent score. It should terminate AI Agents and AI answers before they hit the survey. That is Maxna.

AI Agents
Leaving Research Defender for another score changes nothing.
AI Agents are scored as people if you only model the respondent. Maxna is the alternative because the decision includes behavior and the verbatim. See the agent note.

FAQ
Straight answers
Why leave Research Defender?
Because a respondent score is not a gate, does not grade open-ends, and does not catch AI Agents. Maxna does all three.
