User Interviews is primarily a participant-recruitment platform. Diaform runs AI-led conversations with people you can already reach. Respondent, Prolific, Wynter, and Sprig solve other parts of the research workflow.

Only the panel products directly replace recruitment. Diaform and Sprig are included because teams often discover that moderation or in-product reach—not recruiting—is the real constraint.
Diaform conducts adaptive voice or text conversations through a shareable link and organizes each completed response. It is a fit when you can recruit participants yourself. Plans start at $49/month after the trial.
Respondent is the closest category match when the job is recruiting verified professionals for research. Compare current participant fees, screening, audience coverage, and researcher workflow directly with User Interviews.
Prolific is oriented toward research participant recruitment and data quality, particularly for survey and academic-style studies. Check whether its available audience matches the professional or customer profile you need.
Wynter combines a B2B audience with structured message and preference testing. It is narrower than a general research-recruitment marketplace and better aligned with website, positioning, and buyer-message questions.
Sprig is not a recruitment marketplace. It is relevant when you can reach users at a specific product moment and want in-product surveys or experience research instead of a separate recruited session.
Recruitment, moderation, in-product feedback, and analysis are different jobs. Replacing the wrong one creates more work, not less.
Choose User Interviews, Respondent, Prolific, or another panel when finding and screening people is the constraint. Diaform does not replace participant recruitment.
Choose an AI-led conversation tool when you already have an audience but scheduling and conducting every session limits the number of conversations you can run.
Choose an in-product research product when the trigger and interface inside your app matter more than a standalone conversation link.
Diaform replaces the repeated conversation session for research you can recruit yourself. It can complement a panel when you need both recruitment and asynchronous conversation execution.
The AI follows your project questions and context, asks relevant follow-ups, and conducts each voice or text conversation without a researcher joining live.
Share a published link with customers, churned users, beta participants, or a community you can contact. Diaform does not provide a respondent marketplace.
Respondents choose voice or text in a browser. Your team receives the full message history rather than only a generated analysis.
Each completed conversation includes summaries, sentiment, answer confidence, and optional notable quotes alongside the transcript for verification.
Configure project actions for relevant moments and enable Slack notifications when a completed conversation is ready for the team to review.
Diaform publishes Starter $49/mo, Standard $89/mo, Pro $199/mo, and Business $499/mo, plus custom Enterprise plans. A 14-day trial is available before choosing a paid plan.
Use User Interviews when participant access is the problem. Use Diaform when you already have access and conversation execution is the problem.
