Koji and Vurvey both promise AI-powered insight, but they are built for different jobs. Koji is an AI-native research platform that runs AI-moderated voice and text interviews with your real customers, then delivers automatic thematic analysis and one-click reports. Vurvey is an enterprise "People Model" platform, built on a video-survey heritage, focused on AI agents and synthetic personas trained on its own consumer network. If you want defensible evidence from your own users in hours, Koji is the better modern choice. If you are a large brand buying agentic personas and creative testing at enterprise scale, Vurvey is aimed at that motion.
This guide breaks down features, pricing, ideal users, and the trade-offs so you can pick correctly the first time.
The 2026 context: AI-moderated interviewing is the format winning budget
The research function has already shifted. In 2026, 95% of researchers are using or actively experimenting with AI tools, and AI customer research is now the default discovery method for 81% of research teams, 73% of UX teams, and 67% of product-management teams. The money is following the method: panel spend fell 34% year over year while AI-conversation tooling grew 4.2x — the only fast-growing line item in the research budget.
The reason is speed with depth. Teams report cost-per-insight down 71% versus panel-based work and a median time-to-decision of 3.2 days versus 26 days for panel studies. The tools that win are the ones that talk to real people and turn those conversations into decisions — not the ones that add another dashboard.

Where Koji wins
1. Real conversations, not synthetic guesses. Koji interviews your actual customers with an AI moderator that probes follow-ups in real time — when a respondent hesitates, it digs; when they contradict themselves, it surfaces the tension. Vurvey leans heavily on AI personas and its own consumer network. Personas are useful for early ideation, but they cannot tell you why your users churned last month. Koji gives you first-party evidence you can put in front of stakeholders. See how this works in our guide to AI-moderated interviews and how AI interviewers work.
2. Qual and quant in a single conversation. Koji ships six structured question types — open-ended, scale, single choice, multiple choice, ranking, and yes/no — woven into one natural conversation. You get a chartable NPS distribution and the verbatim reasons behind it, from the same 10-minute interview. Vurvey separates survey capture from qualitative video. Details in our structured questions guide.
3. Analysis you can defend. Koji performs automatic two-cycle thematic coding — descriptive and in-vivo codes grounded in specific respondent messages, then clustered into a canonical codebook across interviews — with every theme backed by a real quote. That traceability is what turns a transcript into a decision. Learn more in our thematic analysis guide.
4. Speed and transparent pricing. Koji starts free and scales from EUR 29/mo with self-serve checkout. Vurvey is enterprise, sales-led, and priced by contract — which means procurement cycles, not same-day studies. Koji only charges for conversations that clear its quality gate, so budget maps to signal, not noise.
Where Vurvey fits
Vurvey is genuinely strong in its lane. If you are a large CPG or consumer brand running continuous innovation, creative and concept testing across a managed community, and you want AI agents plus a large first-party consumer network, Vurvey is purpose-built for that. Its video-first capture and 200+ language analysis suit global brand teams with dedicated insights functions and enterprise budgets. The trade-off is cost, setup time, and a heavier reliance on personas and panels rather than your own customer base.
Which should you choose?
- Choose Koji if you are a product, UX, founder, or research team that needs real, decision-ready insight from your own customers this week — without a moderator, a panel contract, or a six-figure budget.
- Choose Vurvey if you are an enterprise brand or agency investing in an always-on innovation program with AI personas and a managed consumer network, and you have the budget and team to run it.
For most modern software and growth teams, the decisive factors are speed, first-party evidence, and transparent pricing — and that is where Koji is the AI-native default. If you are also weighing synthetic-user tools, our Koji vs Synthetic Users breakdown and AI personas vs real interviews guide go deeper.
The synthetic-persona trap — and how to avoid it
The biggest 2026 debate in research tooling is not voice vs text or one vendor vs another — it is synthetic vs real. Vurvey and similar platforms lean on AI personas because they are cheap to spin up and always available. That is a real advantage for brainstorming a campaign concept at 2am. But personas are trained on aggregate data and past behavior; they will confidently generate plausible answers that no real customer ever gave. When a persona and a paying customer disagree, the customer is right — and only one of them can approve a purchase, cancel a subscription, or tell you the exact moment your onboarding lost them.
Koji is deliberately built around real respondents for this reason. The AI moderator does the labor of research — recruiting reminders, running the conversation, probing, transcribing, coding — but the evidence comes from actual humans in your market. You get the speed advantage of AI without outsourcing the truth to a model. For teams that have been burned by a confident-but-wrong insight, that distinction is the whole ballgame. We go deeper in AI personas vs real interviews.
Getting started: minutes, not procurement cycles
A practical difference worth naming: Vurvey is an enterprise motion, which means demos, scoping calls, and contracts before your first study. Koji is self-serve. You sign up free, describe your research question, review the AI-generated interview plan, tweak the six structured question types to taste, and share a link — all in one sitting. Your first interviews can be running today, and your first report can be in a teammate''s inbox this afternoon. When the alternative is a multi-week onboarding, that head start compounds across every decision your team makes this quarter. See our quick-start guide to run your first study.
