How it works
To use QualiaInterviews you need credits. We pay 500 credits (equivalent to £50) for free into your account every year, enough for 25 GPT-4.1 interviews or 50 GPT-4.1-mini interviews.
Every time a respondent completes an interview (with five or more AI responses after the first greeting), we deduct credits from your account.
Non-profit and 'for-good' organisations: apply for more free credits.
