Koji is an AI-native customer research platform (from as low as €1 per qualified interview, voice from €3, free to start with 10 credits and no subscription needed) focused on AI-moderated voice and chat interviews with dynamic follow-ups, six structured question types, automatic thematic analysis, and one-click cited reports, on transparent EU self-serve pricing. Voicepanel wins on consumer panel breadth and method coverage; Koji wins on structured, mixed-method interview depth and transparent access for product, B2B, founder, and CX teams.","content":"**TL;DR:** Voicepanel and Koji are both AI-native research platforms that conduct interviews and synthesize the results automatically — the modern alternative to static surveys. Voicepanel leans broad and consumer-scale: voice, video, surveys, phone calls, and usability tasks, with a built-in panel of 30M+ people and an unlimited-responses model starting at $99. Koji leans deep and structured: AI-moderated voice and chat interviews built around six structured question types, automatic thematic analysis, and transparent EU pricing you can start free. Both are strong AI-first choices; the right one depends on whether you need a wide consumer panel or structured, mixed-method depth.\n\n## Quick answer: which one should you pick?\n\n- **Choose Voicepanel** if you need a large built-in consumer panel, want one tool spanning voice, video, surveys, and usability tasks, and prefer an unlimited-responses pricing model for high-volume B2C work.\n- **Choose Koji** if you want AI-moderated voice and chat interviews with six structured question types in a single study, automatic theme coding, and transparent self-serve pricing — ideal for product, founder, B2B, and CX teams who want depth fast.\n\nBoth replace the slow survey-and-code loop with AI that interviews and analyzes for you. The decision is about panel breadth versus structured, mixed-method depth.\n\n## What Voicepanel actually does\n\nVoicepanel (a Y Combinator company) positions itself as \"AI agents for customer research.\" Its strengths are breadth and scale:\n\n- **Many methods, one platform** — surveys, evals, voice, video, phone calls, and usability tasks, with support for prototypes, websites, and mobile apps.\n- **Large built-in panel** — access to 30M+ consumers and professionals across 150+ countries, plus 10+ panel partners (User Interviews, Respondent, Prolific, and more).\n- **AI analysis** — automated summaries and AI-generated themes backed with quotes, audio, and video clips, in 35+ languages.\n- **Enterprise-grade compliance** — SOC 2 Type II, GDPR, and HIPAA compliant, and it does not train on customer data.\n\nVoicepanel is a strong fit for teams that need consumer reach across many modalities. Its trade-off is focus: spanning surveys, tasks, voice, and video means its interview experience is one capability among many, rather than a deep, structured interview engine.\n\n## What Koji actually does\n\nKoji is built interview-first, with structure at its core:\n\n- **AI-moderated voice and chat interviews** that adapt in real time, asking the dynamic follow-up a static survey never would. See [AI-moderated interviews](/docs/ai-moderated-interviews) and [voice vs text interviews](/docs/voice-vs-text-interviews).\n- **Six structured question types** — open-ended, scale, single-choice, multiple-choice, ranking, and yes/no — in one study, so you get quantifiable signal *and* the qualitative \"why.\" Far more than a survey-or-interview binary; see [AI interviews vs surveys](/docs/ai-interviews-vs-surveys).\n- **Automatic thematic analysis** — every transcript is auto-coded and themes clustered across all conversations. See [AI auto-tagging](/docs/ai-auto-tagging-customer-interviews) and [thematic analysis](/docs/thematic-analysis-guide).\n- **One-click reports + transcript chat** — ask a question across 100 interviews and get a cited answer in seconds via [chat with transcripts](/docs/chat-with-interview-transcripts-ai).\n- **Recruit and launch fast**: pull participants [from your product](/docs/recruiting-from-your-product), import your own, or have Koji recruit them from a global panel network at a per-respondent quote in credits you approve before launch, then go live 24/7 with no moderator bias.\n\nFrom research question to synthesized, auto-coded insight in hours — with no research expertise required. Koji runs [GDPR-compliant research](/docs/gdpr-compliant-ai-user-research) on EU-transparent pricing.\n\n## Head-to-head comparison\n\n| Capability | Voicepanel | Koji |\n|---|---|---|\n| Core focus | Broad multi-method + panel | Structured AI interviews |\n| Modalities | Voice, video, survey, phone, tasks | Voice + chat |\n| Structured question types | Survey-style | 6 types in one study |\n| Built-in consumer panel | 30M+ | Your users, imports, or built-in panel recruitment (quoted in credits) |\n| Automatic thematic analysis | Yes | Yes, across every interview |\n| Dynamic follow-up questions | Yes | Yes |\n| Pricing | Free; from $99; custom | From €1 per qualified interview, voice from €3; free to start with 10 credits |\n| Best fit | High-volume B2C reach | Product, B2B, founders, CX |\n\n## Pricing: the honest breakdown\n\nVoicepanel offers a free-forever tier and paid plans starting at **$99/month** with an unlimited-responses model, scaling to custom enterprise — attractive if you run high-volume consumer studies and value not being metered per response.\n\nKoji is transparent and self-serve in euros, and interviews start as low as **€1 per qualified interview and €3 per qualified voice interview**. You start free with 10 credits and no card, then pay as you go with no subscription at all, so you pay only for the interviews your study actually uses. Volume pricing, plans and custom **Enterprise** are there when you want them. There is no overage, and a conversation that scores below 3 out of 5 is free and never charged, so you only ever pay for the conversations that bring insights.\n\n## Where each one wins\n\nUse Voicepanel when your bottleneck is *reach* — you need a large, diverse consumer panel and want to mix surveys, tasks, and video in one place for B2C research at scale.\n\nReach for Koji when your bottleneck is *depth and structure* — [B2B customer research](/docs/b2b-customer-research-ai-interviews), [continuous discovery](/docs/continuous-discovery-user-research), [churn diagnosis](/docs/churned-customer-interviews), or [concept testing](/docs/concept-testing-methodology) where mixing scale and open-ended questions in one study, and getting clean theme coding, matters more than raw panel size. Both platforms take compliance seriously; Koji documents its approach to [data privacy and security](/docs/ai-interview-data-privacy-security) and [bias mitigation](/docs/ai-interview-hallucinations-bias-mitigation).\n\n## B2B depth vs B2C reach: a quick decision guide\n\nThe cleanest way to choose between Voicepanel and Koji is to look at *who* you need to talk to. If your research is broad consumer work — hundreds of responses from a representative slice of the general public — Voicepanel's 30M-person panel and unlimited-responses model is built for that reach.\n\nIf your research is about *your* customers — current users, churned accounts, trial drop-offs, target-account buyers — then a general consumer panel is the wrong instrument. You need to interview specific, named people, and you need structured depth from each conversation. That is Koji's wheelhouse: [recruit from your product](/docs/recruiting-from-your-product), import a CRM segment, or share a personalized link, then run an AI-moderated interview that mixes a satisfaction scale, a ranking question, and open-ended probing in a single session.\n\nThis is also why structured question types matter more than they first appear. A survey gives you numbers without the why; a pure interview gives you the why without comparable numbers. Koji's six question types let one study do both — so a [product-market-fit](/docs/ai-interviews-vs-surveys) check can quantify how disappointed users would be without you *and* capture the reasoning behind each answer, coded into themes automatically.\n\nFor high-volume B2C concept and ad testing, Voicepanel's breadth is a real advantage. For B2B and product teams who need to interview their own users with structured depth and ship insights weekly, Koji is the more focused tool — and its transparent pricing means you can prove the value before you ever talk to sales.\n\n## The bottom line\n\nVoicepanel and Koji are both modern, AI-native research platforms — a clear upgrade over static surveys and manual coding. Voicepanel wins on consumer panel breadth and method coverage. Koji wins on structured, mixed-method interview depth and transparent access. If your work is high-volume B2C with a need for built-in reach, try Voicepanel. If you want structured AI interviews you can launch today and trust to code themes for you, start with Koji.\n\n**Ready to run real customer interviews?** [Start with Koji free](https://www.koji.so) — 10 credits, no credit card, your first AI-moderated study live in minutes.
