Koji is an *AI-moderated interview* platform — the AI asks the question, listens to the answer, and asks intelligent follow-ups in real time. If you need genuine probing depth (not just video soundbites), Koji is the modern alternative, from as low as €1 per qualified interview and free to start with 10 credits.\n\n[Voxpopme](https://www.voxpopme.com) pioneered the asynchronous video research category. The format works: participants click a link, watch a prompt, and record a 30-90 second video reply. AI then transcribes and themes the clips. For producing customer-quote video reels and capturing authentic emotional reactions to ads, it has clear utility.\n\nBut video surveys hit a hard ceiling: they cannot ask a follow-up. If a participant gives a vague or surface-level answer, the platform has no way to probe further. Koji solves that by replacing the recorded prompt with an AI moderator that conducts a live conversation. This guide walks through every meaningful difference.\n\n## Quick comparison table\n\n| Feature | Koji | Voxpopme |\n|---|---|---|\n| **Format** | Live AI-moderated voice/text interview | Pre-recorded one-way video survey |\n| **Real-time follow-ups** | Yes — AI probes vague answers automatically | No — clip ends when participant stops talking |\n| **Structured questions in same session** | 6 types (open/scale/single/multi/ranking/yes-no) | Closed-ended questions supported, but no live blending |\n| **Voice stack** | ElevenLabs real-time conversational voice | Participant self-records video |\n| **Automatic thematic analysis** | Yes — AI clusters every conversation | Yes — ChatGPT-powered theme extraction |\n| **Video output for executive reels** | Transcript + verbatim quotes (no auto-reels) | Polished video showreels |\n| **Starting price** | Free with 10 credits; from €1 per qualified interview, voice from €3 | Custom enterprise pricing (admin seats + add-ons) |\n| **Free tier** | 10 credits at signup | Free trial only |\n| **Best for** | Founders, PMs, researchers needing *depth* | Brand teams capturing emotional video moments |\n\n## The core difference: one-way vs. two-way\n\nVoxpopme is one of the strongest one-way video platforms on the market. Its product runs an asynchronous workflow: a stimulus video plays, the participant records a video reply, and AI analyzes the clips at the end. Voxpopme positions this as \"60x faster analysis\" — and for the format it supports, that claim holds up.\n\nBut \"one-way\" is the constraint. The platform cannot react to what a participant just said. If a customer says *\"the onboarding was confusing\"* — the most important moment in the entire interview — Voxpopme cannot ask *\"which step? show me where it broke down?\"* That follow-up only happens in a live conversation.\n\nKoji replaces the one-way clip with a real conversation. The platform's [AI-moderated voice interview engine](/docs/ai-voice-interviews-definitive-guide) listens, interprets, and probes — 24/7, with no human moderator. A respondent clicks a link, has a 10-15 minute voice or text conversation with the AI, and Koji handles transcription, theming, and reporting automatically.\n\nThis is why Koji shows up in every recent [Voxpopme alternatives](/blog/koji-vs-listen-labs-2026) round-up: it solves the depth problem at the data-collection layer, not the analysis layer.\n\n## Pricing and access\n\nVoxpopme uses an enterprise-style pricing model in 2026. Quotes are tailored: you pay for admin seats, optional add-ons, and access to Voxpopme's respondent panel. There is no public price page beyond a \"request a quote\" form, and most reviews on G2 and Capterra describe annual contracts negotiated through sales.\n\nKoji takes the opposite approach:\n\n- **Free** — 10 credits at signup, no card on file\n- **Interviews from €1:** as low as €1 per qualified interview, and €3 per qualified voice interview\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\nFor a founder running a 20-interview product validation study, Koji starts at €20 for text or €60 for voice, entirely self-serve, signup to first interview in under 15 minutes. Voxpopme cannot match that price point or speed because the model assumes a sales-cycle commitment.\n\n## Feature-by-feature\n\n### Probing depth\n\nThis is Koji's biggest advantage. Customer research depends on the *follow-up* question more than the initial one. A 2024 study referenced in industry research benchmarks (Cobloom, B2B churn analysis) found that initial survey responses matched the actual underlying churn driver in only 31% of cases — the truth came out 2-3 probes deep. A platform that cannot probe is a platform that systematically misses 69% of the real story.\n\nKoji probes automatically. Voxpopme cannot.\n\n### Question variety\n\nKoji supports six structured question types blended into the same conversation: open-ended, scale, single-choice, multi-choice, ranking, and yes/no. The AI asks them naturally — *\"On a scale of 1-7, how easy was checkout?\"* — and the answers are stored as both qualitative quotes *and* quantitative data points. See the [structured questions documentation](/docs/choice-ranking-questions-guide) for the full breakdown.\n\nVoxpopme supports closed-ended questions, but its core unit is a video clip, so the blend of quant + qual depth in a single 12-minute session is harder to achieve.\n\n### Output and reporting\n\nThis is where Voxpopme has a genuine edge. The platform produces polished video showreels that put real customer faces and voices in front of executive audiences — a powerful artifact for steering committees and brand strategy decks. If your goal is *\"make leadership feel the customer pain,\"* Voxpopme's video output is hard to beat.\n\nKoji's [research reports](/docs/generating-research-reports) are text-and-quote based. The platform produces an executive summary, theme clusters, sentiment breakdown, and verbatim quotes you can paste straight into a deck. Koji does not produce auto-edited video reels — that is a deliberate trade-off in favor of depth and structured data.\n\n### Recruitment and panels\n\nVoxpopme offers access to its proprietary respondent panel (sold as an add-on). Koji has panel recruitment built in on paid plans: describe your audience and Koji returns a live per-respondent quote from Koji's panel, shown and paid in credits, which you approve before launch. You can also share a link with your own customers or pair Koji with networks like [User Interviews](/blog/koji-vs-userinterviews-2026) or [Respondent](/blog/koji-vs-respondent-2026) for specialty samples.\n\nFor B2B and product-led teams (where you usually own your participant list — existing customers, churned users, beta signups), Koji's share-link model is faster. For consumer brand work where you need fresh general-population samples, both platforms can source them; Koji shows the panel quote in credits and you approve it before launch.\n\n## When to choose which\n\n**Choose Koji if you need:**\n- Live AI follow-ups that uncover the *real* reason behind surface answers\n- Structured + qualitative data in one session (replace a survey + interview combo)\n- Self-serve pricing with no annual contract\n- Always-on customer feedback that runs 24/7\n- Customer discovery, [churn analysis](/docs/churn-analysis-ai-interviews), [feature prioritization](/docs/feature-prioritization-ai-interviews), or [B2B SaaS research](/docs/b2b-customer-research-ai-interviews) where depth matters more than video aesthetic\n\n**Choose Voxpopme if you need:**\n- Polished customer-video showreels for executive presentations\n- Asynchronous emotional reaction capture (ad testing, package design)\n- Access to Voxpopme's built-in respondent panel for general-population consumer research\n- A primary deliverable that is a video, not a written insight report\n\n## Why teams switch from Voxpopme to Koji\n\nThe most common switch we see: a research team buys Voxpopme for video output, then realizes their actual research questions need probing depth. Once you start asking *\"why?\"* on a vague answer, video surveys stop scaling. Industry data on customer retention amplifies the cost of getting it wrong: increasing customer retention by 5% can lift profits by 25-95% (Bain & Company), and you cannot fix retention with surface-level video clips.\n\nThree concrete reasons teams switch:\n\n1. **Real follow-ups beat polished clips** — for actually understanding customers\n2. **Self-serve pricing** — no annual contract or six-figure commitment\n3. **Quant + qual in one session** — replaces both the Typeform survey and the Calendly call\n\nVoxpopme is the right tool for \"produce a video reel of customer reactions.\" Koji is the right tool for \"actually understand what customers think, why they churn, or what they would buy.\"\n\n## Try Koji free\n\nStart at [koji.so](https://www.koji.so) with 10 free credits — enough for 3 voice interviews — no card required.

The platform cannot ask a follow-up if an answer is vague or surprising. Koji's AI moderator probes in real time, which research data shows uncovers underlying drivers in roughly 3x as many cases as one-way formats.","question":"Can Voxpopme do real-time follow-up questions like Koji?"},{"answer":"No. Koji focuses on structured insight reports — executive summary, theme clusters, sentiment, and verbatim quotes — rather than auto-edited video showreels.

If your deliverable is an insight report or product decision, Koji wins.","question":"Does Koji produce video reels like Voxpopme?"},{"answer":"Koji. B2B research depends on probing depth (multi-stakeholder buying committees, technical feature feedback), and Voxpopme's one-way format cannot probe. Koji's self-serve credit pricing, structured question types, and quick setup also fit B2B workflows where you already own the participant list of customers and prospects.
