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 starting at **€79/month**, 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** | €79/month, transparent credits | 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).\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- **Insights plan:** €29/month (29 credits)\n- **Interviews plan:** €79/month (79 credits)\n- **Overage:** flat €1/credit\n- **Credit costs:** text interview = 1 credit, voice interview = 3 credits (~€3), report refresh = 5 credits\n- **Quality gate:** only conversations scoring 3+ on quality consume credits — drop-offs and junk are free\n\nThat means a startup or agency can run a full round of in-depth concept interviews on Koji for less than the cost of lunch, and validate the whole platform for under €80. 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, starting at €79/month.\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.
