How Credits Work
Credits are the currency of Koji. Different actions cost different amounts:
| Action | Credit Cost |
|---|---|
| Text chat interview | 1 credit |
| Voice interview | 3 credits |
| Report refresh | 5 credits (free on Interviews+) |
Key rules:
- Credits reset monthly on your billing anniversary
- The quality gate protects your budget — conversations scoring below 3 on the 1-5 scale are completely free
- Overage credits are billed at a flat €1/credit on paid plans — learn more about overage
- You can set an overage cap to control unexpected costs
- Structured questions (scale, choice, ranking, yes/no) are included in every interview at no extra credit cost — giving you both qualitative depth and quantitative data in a single credit
What Are Structured Questions?
Koji supports quantitative structured questions alongside its signature conversational depth. Every plan includes:
- Scale questions (1-5, 1-7, 1-10) — for NPS, CSAT, satisfaction ratings
- Single choice — radio-button-style selection
- Multiple choice — multi-select options
- Ranking — drag-and-drop preference ordering
- Yes/No — binary questions
- Open-ended — free-text for qualitative depth
The AI interviewer delivers these conversationally, naturally weaving quantitative data collection into qualitative conversations. This makes Koji the only platform that combines survey-scale data collection with interview-depth insights — and structured questions consume no extra credits beyond the standard interview cost.
