Maxna vs Research Defender (Rep Data)
Maxna vs Research Defender / Rep Data. Do not confuse a quality score on the respondent with sample integrity. Agents and AI open-ends still sail through a person-only 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
Research Defender is a respondent-quality score. It rates the person. It does not grade the answers, and it does not stop an AI Agent. Maxna is a live pass/fail gate: respondent quality plus proprietary AI on the response.

AI Agents
A respondent score will not catch AI Agents.
Research Defender-class tools score whether the attempt looks like a real panelist. An AI Agent is designed to look like a real panelist: real browser, real device, paced clicks. The score can stay green while the agent writes every open-end. Maxna fails that session on interaction physics, paste/timing, and proprietary AI on the text. You cannot buy your way out of agent fraud with a person-only quality number. Full write-up: AI Agents vs identity-only and score-only survey tools.
Fit
When you need Maxna

You do not want the sample seller scoring the sample
Maxna does not sell sample. Integrity is the product.
AI Agents and AI answers are in your waves
A respondent score does not read AI Agent sessions or ChatGPT verbatims. Maxna does.
