    AI-Powered UX Research

    User research generates massive amounts of qualitative data—interview transcripts, survey responses, observation notes. AI can dramatically accelerate synthesis. But which model produces better UX insights?

    We tested GPT-5 and Claude 4.6 on real UX research workflows.

    Interview Analysis

    Test: Analyze 20 user interview transcripts (45 minutes each), identify themes, pain points, and opportunities. Claude 4.6 identified 23 distinct themes with nuanced relationships between them. GPT-5 identified 19 themes with clearer prioritization.

    Claude's analysis was more comprehensive; GPT-5's was more actionable. UX researchers preferred Claude's output 58% of the time.

    Theme Synthesis

    Synthesizing themes across interviews is crucial. Claude excelled at identifying subtle connections and contradictions between users. GPT-5 produced cleaner theme hierarchies but occasionally missed nuance.

    For exploratory research, Claude's depth matters. For validation research, GPT-5's clarity helps.

    Persona Generation

    Both models generated user personas from research data. Claude's personas felt more human and nuanced, with realistic contradictions. GPT-5's personas were more structured and immediately usable in design discussions.

    Product teams without UX experience preferred GPT-5's personas. Experienced researchers preferred Claude's.

    Insight Quality

    The ultimate test: do AI-generated insights lead to better design decisions? We had design teams use insights from both models. Claude-informed designs scored higher on addressing user needs. GPT-5-informed designs scored higher on implementation clarity.

    Both approaches improved over no-AI baselines.

    Recommendations

    Choose Claude 4.6 for: deep exploratory research, complex user journeys, nuanced persona development, and identifying non-obvious patterns. Choose GPT-5 for: validation research, stakeholder presentations, actionable recommendations, and structured deliverables.
