Frequently Asked Questions
What is QuestionPunk?
QuestionPunk is an AI-powered survey and research platform that turns traditional surveys into adaptive conversations. Describe your research goal and get a complete survey draft, conduct AI-moderated interviews with dynamic follow-ups, detect low-quality responses, and produce insights automatically. It's fast, flexible, and scalable across qualitative and quantitative research.
How do I create my first survey?
Sign up, then choose how to build: describe your research goal and let AI generate a survey, pick a template, or start from scratch. Add question types, set logic, preview, and share.
Can the AI generate a survey from a prompt?
Yes. Describe your research goal in plain language and QuestionPunk drafts a complete survey with appropriate question types, ordering, and AI follow-up logic. You can then customize before publishing.
What question types are available?
QuestionPunk supports a wide range of question types: opinion scale, rating, multiple choice, dropdown, ranking, matrix, constant sum, AI interview (text and audio), long text, short text, email, phone, date, address, website, numeric, audio/video recording, contact form, chat message, conversation reset, button, page breaks, and more.
How do AI interviews work?
AI interviews conduct adaptive conversations with respondents. The AI asks follow-up questions based on what the respondent says, probing for clarity and depth. You control the personality, tone, model (Haiku, Sonnet, or Opus), and question mode (fixed count, AI decides when to stop, or time-based).
Can I test my survey before launching?
Yes. Use synthetic testing to create AI personas and run them through your survey. This helps catch issues with question flow, logic, and wording before real respondents see it.
How many languages are supported?
QuestionPunk supports 142+ languages. Add languages from the survey editor, auto-translate questions, and share language-specific links. AI interviews also adapt to the respondent's language automatically.
How can I share my survey?
Share via a direct link (with optional custom slug), embed on your website (iframe or script), distribute through Prolific for research panels, or generate a QR code for physical distribution.
Can I export survey results?
Yes. Export as CSV (flat or wide layout), Excel (XLSX), or export the survey structure as PDF/Word. Filter by suspicious level, response type, language, or date range before exporting.
Does QuestionPunk detect fraudulent responses?
Yes. Every response is automatically classified with a suspicious level (low/medium/high) based on attention checks, response timing, and behavioral signals. You can filter flagged responses in the Responses tab.
What are the pricing plans?
Basic (Free): 20 responses/month. Business ($50/month or $500/year): 5,000 responses/month with priority support. Enterprise (Custom): unlimited responses, remove branding, custom domain, and dedicated support.
How long does support take to reply?
We reply within 24 hours, often much sooner. Include key details in your message to help us assist you faster.
