Koji is an AI-native customer research platform (Free with 10 credits, €29/mo Insights, €79/mo Interviews) 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) or import your own, and 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+ | Recruit from your users / import |\n| Automatic thematic analysis | Yes | Yes, across every interview |\n| Dynamic follow-up questions | Yes | Yes |\n| Pricing | Free; from $99; custom | Free (10 credits); €29/mo; €79/mo |\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: a **Free** plan with 10 credits to run real interviews today, **Insights at €29/month**, **Interviews at €79/month**, and custom **Enterprise**. Voice interviews cost 3 credits, text costs 1, and a quality gate means only conversations scoring 3+ consume credits — so you never pay for junk responses. The credit model rewards precision over volume, which suits teams that want signal, not noise.\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.
