Plan Comparison Guide

Koji Pricing Overview

Interviews start as low as €1 per qualified interview and €3 per qualified voice interview, with reports from €5 per refresh and phone from €0.60 per connected minute. Those floors are the €1.00 annual rate; the full ladder is below. Choose what fits: pay as you go at €2.00 per credit with no subscription at all, one-time packs from €100 (€1.82 down to €1.33 per credit), monthly plans from €199 (about €1.20 per credit), or annual plans at €1.00 per credit with all credits granted on day one. You are never tied to a subscription. There is no overage. You pay as you go, and you only ever pay for the conversations that bring insights.

Koji uses one credit-based model designed so you only pay for quality conversations. Every way of paying includes the quality gate: interviews scoring below 3 on the 1-5 quality scale are free and don't consume credits.

What a credit buys never changes. A text interview is 1 credit, a voice interview is 3 credits, a report refresh is 5 credits, and a phone interview is 0.6 credits per connected minute. What changes is the price you pay per credit, and it only goes down as your commitment goes up.

All prices are in EUR (€).

How Credits Work

Credits are the currency of Koji. Different actions cost different amounts:

Key rules:

• The credit cost of an action is identical on every plan and every way of paying
• The quality gate protects your budget: conversations scoring below 3 on the 1-5 scale are completely free
• There is no overage. You pay as you go, and you only ever pay for the conversations that bring insights. Your study pauses until you top up. Nothing is ever charged automatically. Learn more
• Publishing a study is never blocked by your balance
• 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.
