Build an AI user interview question generator for product, UX, and market researchers. Features: 1) Intake form for the research goal, participant type, session length, methodology (usability test, churn interview, concept test, discovery call), and product context. 2) AI-generated discussion guide organized into warmup, background, core, and closing sections with target timing per section. 3) A leading-question detector that flags biased phrasing and offers neutral rewrites, since leading questions are the most common research mistake. 4) Follow-up probes attached to every core question so interviewers can dig deeper without improvising. 5) Question type tagging (open-ended, scale, task, story) with a balance report showing the mix. 6) A template library of starting guides for common study types, editable before generation. 7) Export to a clean document or copy directly into a session notes template. 8) A participant screener generator that outputs qualifying and disqualifying questions for recruitment.
