1. Moderation Technology: Limited Hearing vs Vision-Aware Probing

AI moderators must adapt in real time to what users say—and see. Only one platform fully does both.

Qualz.ai's engine conducts voice, text or hybrid interviews using LLM prompts and dynamic probes. Userology layers a proprietary LLM with computer vision to observe UI interactions and ask targeted follow-ups.

How Userology's AI Moderation Stands Apart

FeatureBasic AI moderationNew‑Gen AI moderation (Userology)
Interaction ModalityChat‑ or text‑based UI requiring participants to read each prompt and click to answer and proceedNatural voice‑driven conversations over video call; no clicks needed
Participant FocusParticipant must alternate between reading prompts and answeringParticipant stays focused on talking rather than reading - proven smoother experience
Flow ControlDiscrete, sequential Q&A—participant must manually click to submit and proceedContinuous conversational flow: AI listens, pauses, then prompts next question
Stimuli IntegrationStatic stimuli (images, links) viewed separately; no contextual AI awarenessIntegrated live stimuli testing (websites, prototypes) monitored during session with AI vision
Task‑Flow ContextAI cannot observe on‑screen actions or adapt during interactionsAI can ask while the user clicks, scrolls, or taps, giving richer task‑flow context by observing actions
Conversation contextNo real‑time adaptive probing based on old answers, can lead to question repetitionHas entire context in memory and doesn't repeat same or similar questions
Vision & Emotion AnalysisAbsent—no automated analysis of facial expressions or on‑screen contextPresent—AI analyzes facial and screen cues to tailor questioning

Why This Matters

Userology's advanced AI moderation creates a more natural research experience that yields deeper insights. By combining voice-driven conversations with vision-aware context, participants can focus on their experience rather than navigating a chat interface, resulting in more authentic feedback and higher-quality data.

Conclusion: Synthetic Speed vs UX Depth

  • Choose **Qualz.ai** for credit-driven interview automation, dynamic surveys, and AI Participants when rapid, synthetic feedback suffices.
  • Choose **Userology** for vision-aware usability tasks, native mobile testing, deeper UX analytics, and real human insights at scale.

Userology's richer method coverage, computer-vision follow-ups, longer sessions, and human panel make it the most versatile AI-moderated UX research platform of 2025.

Frequently Asked Questions About AI-Moderated UX Research

Based on our in-depth comparison, Userology generally outperforms Qualz.ai for AI usability testing due to its vision-aware task analysis, native mobile testing capabilities, and support for 180+ languages. While Qualz.ai offers basic interview functionality, Userology provides comprehensive UX research capabilities including task success metrics, screen recording analysis, and deeper insights into user behavior patterns.

Userology's AI moderation combines both language models and computer vision, allowing it to "see" what participants are doing on screen and ask context-aware follow-up questions. Qualz.ai relies primarily on verbal conversation, missing important visual context during usability tests. Additionally, Userology's platform supports 180+ languages compared to Qualz.ai's more limited language options, making it ideal for global research studies.

Userology offers native iOS and Android apps for mobile usability testing, providing a seamless experience for participants. The platform can observe and analyze touch interactions, gestures, and navigation patterns in real-time. Qualz.ai generally lacks dedicated mobile testing capabilities and relies on browser-based testing, which can miss important mobile-specific interactions and friction points that impact user experience.

AI-moderated user research uses artificial intelligence instead of human moderators to conduct interviews, usability tests, and other research activities. This approach scales research capacity, eliminates moderator bias, and allows teams to run hundreds of parallel sessions with consistent quality. AI moderation particularly excels at maintaining consistent questioning across all participants, detecting subtle usability issues through pattern recognition, and providing immediate insights without the delays of traditional research methods.

Modern AI usability tests can achieve 85-95% of the insight quality of human moderation, with the advantage of consistency across all sessions. Userology's vision-aware AI can detect subtle usability issues that even human moderators might miss, particularly with its ability to analyze hundreds of sessions for patterns. The platform combines qualitative insights with quantitative metrics like task success rates, time-on-task, and interaction patterns to provide a comprehensive view of the user experience.

Userology enables several research methodologies that Qualz.ai doesn't support: (1) Vision-aware usability testing that recognizes on-screen elements and user interactions, (2) Native mobile app testing through dedicated iOS and Android apps, (3) Mixed-method studies combining qualitative feedback with quantitative metrics, (4) Longitudinal diary studies for tracking user behavior over time, and (5) Tree testing and card sorting for information architecture research. These capabilities make Userology a more versatile platform for comprehensive UX research programs.

AI-moderated research dramatically simplifies recruitment and participant management. With Userology's platform, you can tap into a 10M+ participant pool across 180+ languages, with first participants joining studies in as little as 6 minutes. The AI handles all session moderation, allowing researchers to run hundreds of parallel sessions without scheduling constraints. This approach reduces study timelines from weeks to hours while maintaining consistent quality across all sessions.
