Koji is an **AI-native interview platform**: instead of multiple-choice surveys, it runs [AI-moderated voice and text conversations](/docs/ai-voice-interviews) that probe *why* customers react the way they do, then auto-codes the themes and writes the report.\n\nIf you are a large CPG brand running standardized, benchmarked concept tests at volume, Zappi is purpose-built for that. If you want genuine customer *understanding* — the reasoning, emotion, and language behind a reaction — at survey speed and a fraction of the cost, Koji is the better fit. And with interviews from as low as €1 per qualified interview and €3 per qualified voice interview, **10 free credits** at signup, and no subscription needed, you can prove it before committing.\n\n## Koji vs Zappi at a glance\n\n| | **Koji** | **Zappi** |\n|---|---|---|\n| **Core method** | AI-moderated voice & text interviews | Automated quantitative surveys |\n| **Best for** | Founders, PMs, researchers, agencies | Enterprise brand & innovation teams |\n| **Signature use case** | Customer discovery, win-loss, churn, concept *why* | Concept, ad, pack & price testing with norms |\n| **Pricing** | From €1 per qualified interview, voice from €3 | Enterprise, quote-based |\n| **Qualitative depth** | Native — adaptive follow-up probing | Survey verbatims + autocoding |\n| **Time to insight** | Hours, 24/7 interviews | ~12 hours idea-to-insight (per Zappi) |\n| **Analysis** | Automatic thematic coding + report | AI Quick Reports, smart autocoding |\n\n## What is Zappi?\n\nZappi is an **automated, agile consumer insights platform** that combines consumer survey data with AI to deliver \"connected insights\" across the innovation and advertising lifecycle. It is trusted by **over 350 brands** and is strongest at **standardized, benchmarked testing** — concepts, ads, pack designs, claims, and pricing — with results validated against in-market outcomes. Forrester's Total Economic Impact study found brands using Zappi saw a **4–7% increase in new-product revenue** versus legacy providers.\n\nZappi's platform delivers answers in roughly **12 hours on average**, with automatically populated charts, AI Quick Reports that summarize results, and smart autocoding for open-ended verbatims. Pricing is enterprise and quote-based — there is no public self-serve tier.\n\nIn short: Zappi is a fast, rigorous *survey* engine for brands that test a high volume of stimuli and want consistent norms to compare against. That is its strength, and it is a real one.\n\n## What is Koji?\n\nKoji is an **AI-native customer research platform** built on conversations rather than checkboxes. You describe what you want to learn; Koji's AI consultant drafts the [interview plan](/docs/understanding-the-research-brief). Respondents take an AI-moderated voice or text interview that adapts in real time, [probing up to three follow-ups per question](/docs/ai-probing-guide) to get past the first, shallow answer. When interviews finish, Koji [automatically codes the transcripts](/docs/coding-qualitative-data), clusters themes with verbatim quotes, and produces a [one-click report](/docs/generating-research-reports). You do not need an audience of your own either. Share the link with your own users, or describe the people you want and Koji recruits them for you, with a live per respondent quote in credits that you approve before anything launches.\n\nKoji is not qual-only, either. Every study can blend [six structured question types](/docs/structured-questions-guide) — open-ended, [scale](/docs/scale-questions-guide), single choice, multiple choice, ranking, and yes/no — so you can run a [Van Westendorp price-sensitivity](/docs/van-westendorp-price-sensitivity-meter) read *and* hear the reasoning behind every number in the same session.\n\n## The core difference: a survey vs a conversation\n\nThis is the heart of the comparison. Zappi asks a respondent to *rate* a concept on predefined scales and optionally leave a comment. Koji *talks* to them about it. When a participant says a new feature feels \"confusing,\" Zappi captures the word; Koji's AI asks \"what specifically felt confusing, and what did you expect instead?\" — and keeps going until the insight is clear.\n\nFor [concept testing](/docs/concept-testing-methodology), that difference is decisive. A score tells you *whether* a concept landed; an AI-moderated interview tells you *why it landed, for whom, and what to change* — which is the part that actually moves a product roadmap. There is no moderator bias, no scheduling, and no analyst queue, because the AI runs every interview identically and codes them automatically.\n\n## Pricing: transparent credits vs enterprise quote\n\nZappi is sold as an enterprise contract with custom, quote-based pricing — fine for a global brand with an annual insights budget, a barrier for everyone else. Koji is transparent and self-serve:\n\n- **Interviews from €1:** as low as €1 per qualified interview, and €3 per qualified voice interview\n- **Free to start:** 10 credits at signup, no card\n- **Pay as you go:** no subscription needed, so you pay only for the interviews your study actually uses. Volume pricing and plans are there when you want them\n- **No overage:** there is no overage. You only ever pay for the conversations that bring insights\n- **Quality gate:** a conversation that scores below 3 out of 5 is free and never charged\n\nThat means a startup or agency can run a real AI-moderated interview for a couple of euros, from €1 per qualified interview, and validate the whole platform with the free signup credits. For teams without an enterprise procurement process, that accessibility is the deciding factor.\n\n## Speed and scale\n\nBoth platforms are fast by traditional standards. Zappi quotes ~12 hours idea-to-insight. Koji interviews go live the instant you publish a link and run **24/7**, with themes generating as responses arrive — and automated thematic analysis runs roughly **28x faster than manual coding** (about 20 minutes versus 567 minutes per study, per a 2024 *JMIR AI* study). With the global market research industry heading toward **$150 billion in 2026**, the teams pulling ahead are the ones compressing the time from question to decision — exactly what AI moderation enables.\n\n## Where Zappi wins\n\nCredit where due: if your work is **high-volume, standardized stimulus testing** — running dozens of ad or pack variants a quarter and comparing each against an established norm database — Zappi's benchmarked survey system and validated in-market correlations are genuinely valuable, and Koji does not offer a comparable norms library. Large CPG and advertising teams are Zappi's sweet spot.\n\n## The verdict\n\n**Choose Zappi** if you are an enterprise brand running frequent, standardized concept/ad/pack tests and you need benchmarked norms and validated in-market predictions.\n\n**Choose Koji** if you want to understand *why* customers think what they think — the language, motivations, and objections behind the score — at survey speed, with built-in structured questions when you need numbers too, from as low as €1 per qualified interview, starting free with 10 credits and no subscription needed.\n\nMost teams do not lack survey scores. They lack the conversation that explains them. That is the gap Koji closes.\n\n## Try Koji free\n\nSpin up your first AI-moderated concept or discovery study in minutes: describe your goal, let Koji draft the interview, and share the link. You will have themed insights and a finished report before a traditional survey would have cleared fielding.
