TL;DR: QuestionPro is a mature, feature-rich online survey and CX suite built for teams that need 30+ question types, panels, and SPSS-ready exports. Koji is an AI-native customer research platform that moderates the interview itself — running async voice and chat conversations, asking dynamic follow-ups, and auto-coding themes across every response. QuestionPro collects answers to the questions you already thought of. Koji uncovers the why behind them, including the questions you did not know to ask.
Quick answer: which one should you choose?
- Choose QuestionPro if your work is survey-shaped: large-scale quantitative questionnaires, NPS/CX dashboards, panel-sourced samples, and statistical exports for an analyst team that lives in SPSS.
- Choose Koji if you want depth — moderated discovery, churn, win/loss, and product-market-fit interviews where an AI asks the follow-up question a static survey never could, then synthesizes the themes for you in hours.
Both tools gather customer input. The difference is what kind of input. A survey is a one-way form: every respondent sees the same fixed questions and you get back the answers you anticipated. A Koji interview is a two-way conversation: when a customer says "the onboarding was confusing," Koji probes which step, why it broke, and what they expected instead — automatically, at scale.
What QuestionPro actually is
QuestionPro is one of the longest-standing players in online research. In 2026 its survey platform sits across four tiers:
- Essentials — free, single user, up to 200 responses per survey, ~30 question types, basic logic and analytics.
- Advanced — from $99/user/month, adding advanced logic, custom branding, and more export options.
- Team Edition — about $83/user/month billed annually (5-user minimum), up to 100,000 responses/year, shared libraries, and role-based permissions.
- Research Suite / Enterprise — custom pricing, with the QuestionPro Audience panel, conjoint/MaxDiff modules, and CX (NPS+) dashboards.
Reviewers consistently praise QuestionPro for its breadth: a deep question-type library, offline data collection, multilingual surveys, real-time dashboards, and clean SPSS/Excel exports. It is a genuinely strong survey tool.
The recurring complaints are just as consistent: a learning curve on advanced features, the best capabilities gated behind higher tiers, and frustration with tiered pricing and price increases over time. None of that makes QuestionPro a bad product — it makes it a survey product, with all the structural limits that implies.
The structural limit of any survey tool
The ceiling on QuestionPro is not a feature gap. It is the survey format itself.
A survey cannot ask a follow-up. If a respondent leaves a vague open-text answer — "support was slow" — there is no one there to ask "slow how? what were you trying to do?" The insight dies in the cell. Skip logic and branching help you route between pre-written questions, but they cannot improvise a question you did not author in advance. And the richest answers — the open-text boxes — are exactly the ones most teams never fully read, because coding hundreds of free-text responses by hand is slow and inconsistent.
This is the gap Koji was built to close.
What Koji does differently
Koji is an AI-native customer research platform. Instead of sending a form, you brief an AI consultant on your research goal and Koji runs the interviews for you — over voice or chat, asynchronously, in dozens of languages, whenever your participants are free.
- AI-moderated interviews. The AI asks your questions, listens to the answer, and decides — in real time — what to probe next. No moderator on the call, no scheduling, no bias from a tired interviewer on their fifth session of the day.
- Structured questions when you need them. Koji supports six structured question types — open_ended, scale, single_choice, multiple_choice, ranking, and yes_no — so you still get clean, chartable quantitative data alongside the qualitative depth. You are not trading rigor for richness; you get both in one session.
- Automatic thematic analysis. Koji codes themes across every transcript, clusters near-duplicate ideas, and grounds each theme in verbatim quotes. The open-text analysis that takes an analyst days happens automatically.
- One-click reports. From question to a shareable, citable insight report in hours, not weeks — with no research expertise required.
Where QuestionPro hands you a spreadsheet of answers, Koji hands you the findings.
Pricing: how they compare
QuestionPro is priced per seat, and its most useful research features (panels, conjoint/MaxDiff, CX dashboards) live in the custom-priced Research Suite. That is a sensible model for a large insights team — and an expensive, heavy one for a founder or PM who just needs answers this week.
Koji is priced per credit, not per seat:
- Free — 10 credits to start, no subscription required.
- Insights — €29/month (29 credits).
- Interviews — €79/month (79 credits).
- Enterprise — custom.
Each credit maps to a unit of work: a chat interview costs 1 credit, a voice interview 3, and a report refresh 5. A quality gate means only substantive conversations (scoring 3+) consume credits — you are not billed for drop-offs. There is no per-seat tax for adding a teammate to read the results.
Koji vs QuestionPro at a glance
| QuestionPro | Koji | |
|---|---|---|
| Core method | Surveys / questionnaires | AI-moderated voice + chat interviews |
| Dynamic follow-ups | No (fixed + skip logic) | Yes (real-time AI probing) |
| Open-text analysis | Manual / add-on | Automatic theme coding with quotes |
| Quantitative questions | 30+ types | 6 structured types (scale, choice, ranking, yes/no, etc.) |
| Time to insight | Days–weeks (manual coding) | Hours (auto report) |
| Pricing model | Per seat (from $99/user/mo) | Per credit (free, then €29/mo) |
| Best for | Large quant studies, panels, SPSS analysts | Discovery, churn, win/loss, PMF depth |
When QuestionPro still wins
Be honest with yourself about the job. If you need to field a 5,000-respondent quantitative tracker, buy panel sample inside one platform, run conjoint with a dedicated stats team, and export to SPSS — QuestionPro is purpose-built for that and Koji is not trying to be. For high-volume, structured measurement, a survey suite is the right tool.
When Koji is the better choice
For everything that needs the word why, Koji wins on speed and depth:
- Customer discovery — validate a problem before you build. (See our customer discovery sprint guide.)
- Churn and retention — find the real reason customers leave, not the dropdown they picked. (See churned customer interviews and customer retention research.)
- Onboarding friction — hear where new users get stuck. (See user onboarding research.)
- Pricing and willingness-to-pay — go beyond a price grid. (See the willingness-to-pay interview template.)

The bottom line
QuestionPro is a powerful survey suite that has earned its place in the enterprise research stack. But surveys are a 20th-century instrument: rigid, one-directional, and silent the moment a respondent says something interesting. Koji is AI-native — it runs the conversation, follows the thread, and turns raw transcripts into decisions while QuestionPro is still routing skip logic.
If your next research question starts with why, you do not need a bigger survey. You need an interviewer that scales. That is Koji.
