What’s included

  • AI follow-ups

    Adaptive probes on open-ended answers that pull out detail a static form would miss.

  • Attention checks

    Built-in safeguards against rushed answers and low-quality respondents.

  • AI-drafted copy

    Wording, ordering, and branching written by the AI — tuned to your research goal.

  • Auto report

    Themes, quotes, and a plain-English summary write themselves once responses come in.

Why this template

What this template is built to do — we found no directly comparable template from other survey tools to review.

What sets it apart

  • Includes four dedicated opinion-scale questions plus an open-text follow-up isolating endpoint, parameter, response, and pagination clarity rather than lumping 'API quality' into one vague score
  • Separates error-handling friction from auth friction with distinct question blocks (error frequency, error types, error-message helpfulness, a paste-in field for actual unhelpful error text, then a parallel set for API keys, OAuth setup, and token refresh)
  • Closes with an AI follow-up interview question that adaptively probes on whatever the respondent actually reported, plus a drag-and-drop ranking of improvement priorities to directly inform roadmap decisions
  • Captures role, API experience tenure, org size, languages/platforms, and region as segmentation variables so friction points can be sliced by developer profile
