Koji is an AI-native customer research platform that moderates asynchronous voice and chat interviews, runs dynamic follow-ups, and auto-codes themes across studies. Mentimeter ends when the room empties. Koji starts when the link is shared.\n\n## Quick answer: which one solves your problem?\n\n- **Choose Mentimeter** if you want to engage a live audience during a presentation, class, or webinar with real-time word clouds, polls, quizzes, scales, and Q&A.\n- **Choose Koji** if you want to run customer research — discovery, churn, win/loss, value-prop testing — with AI-moderated interviews that don't require you to be in the room.\n\nMentimeter solves the live-engagement problem. Koji solves the ongoing-research problem. They overlap roughly the way Google Slides overlaps with Notion — same family, different jobs.\n\n## What Mentimeter actually does\n\nMentimeter is a web-based interactive presentation platform. You build a deck, embed interactive slides (multiple choice, word cloud, scales, Q&A, quiz, ranking), and audience members join with a code from their phones to respond in real time. The presenter sees aggregated results live and the audience sees them too.\n\nIn 2026, Mentimeter's pricing is:\n\n- **Free** — 50 participant responses per 30-day window, limited interactive question types\n- **Basic** — around $11.99/month (annual billing only)\n- **Pro** — around $24.99/month (annual only), unlimited audience size, custom branding\n- **Enterprise** — contact sales\n\nReviews give Mentimeter 4.7/5 on G2 across 634 ratings. It is genuinely excellent at what it does: putting a temperature check on a room. For lecturers, trainers, conference hosts, and workshop facilitators, nothing is faster.\n\nWhere Mentimeter breaks the moment you try to use it for customer research:\n\n- **It is built around live sessions.** Once the session ends, the engagement model ends with it. There is no scheduled invite link, no async completion window, no ongoing-study workflow.\n- **Qualitative depth is shallow.** The open-text response box is great for word clouds and one-line sentiment — it is not a 5-minute considered answer with dynamic probing.\n- **There is no AI moderator.** A human presenter has to be on the call running the prompts. No \"tell me more about that,\" no branching, no probing.\n- **Cross-session analysis is manual.** Mentimeter shows you what happened in this session — not what 50 customers said over the last 30 days.\n- **The free tier caps at 50 responses/month** which makes it impossible to use as a survey replacement at any reasonable scale.\n\nIn short: Mentimeter is a presentation engagement tool that happens to capture audience input. It is not a research tool, and the team behind it has never claimed it is.\n\n## What Koji actually does\n\nKoji is an AI-native customer research platform built for the workflow Mentimeter was never designed for: asynchronous, moderated, scalable customer interviews.\n\nThe respondent receives a link — by email, in-product, or via a CRM integration — and clicks it whenever it suits them. An AI moderator runs a structured voice or chat interview, asks dynamic follow-up questions when an answer is shallow or interesting, and times the session itself. After every interview, Koji codes themes automatically across the entire study and surfaces them in a one-click report with quotes.\n\nSix structured question types are built in: open-ended, scale, single choice, multiple choice, ranking, and yes/no. You customize the AI consultant per study (tone, expertise, language) and you publish or export the result. See [how AI interviewers work](/docs/how-ai-interviewers-work) for the underlying mechanics.\n\nThis unlocks workflows Mentimeter cannot serve:\n\n- 30+ interviews per week without a calendar slot per respondent\n- Same questions, same depth, same moderation every time — no presenter bias\n- Auto-thematic analysis across all interviews, not \"what did this audience say tonight\"\n- Reports generated in hours, not weeks of manual coding\n- Studies that run continuously, not just during a 60-minute live session\n\nKoji starts free with 10 credits, then €29/month for Insights and €79/month for Interviews. Credit model: 1 credit per chat interview, 3 per voice interview, 5 per report refresh.\n\n## Side-by-side comparison\n\n| Capability | Mentimeter | Koji |\n|---|---|---|\n| Real-time live polling during a presentation | Yes (core feature) | No (not its job) |\n| Asynchronous customer interviews via link | No | Yes |\n| AI moderator with dynamic follow-ups | No | Yes |\n| Requires a live presenter | Yes | No |\n| Six structured question types | Polls + word clouds only | Yes (incl. ranking, scale, multi-choice) |\n| Cross-study thematic analysis | No | Yes — automatic |\n| One-click research report | No | Yes |\n| Voice interviews | No | Yes |\n| Customizable AI consultant per study | No | Yes |\n| Free tier audience cap | 50 responses / 30 days | 10 credits, no audience cap |\n| Entry price | Free; ~$11.99/mo Basic | Free 10 credits; €29/mo Insights |\n\n## Where Mentimeter wins\n\nMentimeter is the right tool when:\n\n- You're a teacher, lecturer, or trainer wanting **live classroom engagement**\n- You're hosting a **conference panel, town hall, or all-hands** with live Q&A\n- You want a **temperature-check word cloud** during a talk\n- Your \"input\" is a quick reaction inside a 60-minute session\n- You're not doing research — you're running a session\n\nIf your use case is \"I'm on stage in 10 minutes and I want the audience to vote,\" nothing beats Mentimeter.\n\n## Where Koji wins\n\nKoji is the right tool when:\n\n- You're doing actual customer research — discovery, churn, win/loss, PMF, value-prop testing\n- You need to interview **30, 100, or 500 customers** without sitting through every call\n- You want **voice interviews** with the depth of a phone conversation but the scale of a survey\n- You need **consistent moderation** across every respondent (no presenter bias)\n- You need **automatic thematic analysis** across the whole dataset\n- You want a **published report in hours**, not weeks\n\nA Mentimeter result is a snapshot of one room. A Koji study is the synthesis of dozens of full conversations.\n\n## The data: where research is moving in 2026\n\nThe market has clearly shifted toward AI-moderated, asynchronous customer research.\n\n- **78% of UX and product teams** use AI in their research workflows in 2026, up from 34% in 2024 — meaning live polling is no longer the cutting edge for understanding customers.\n- **88% of researchers** identify AI-assisted analysis as the top trend impacting research in 2026.\n- Traditional live-group equivalents suffer well-documented **groupthink and dominance bias** — participants conform to the loudest voice in the room. AI-moderated 1:1 interviews remove that bias by design.\n\nThis is the heart of the Koji vs Mentimeter gap. Mentimeter is built on the assumption that everyone is in the same room at the same time. Koji is built on the assumption that everyone is too busy for that.\n\n## Can you use Mentimeter for customer research?\n\nYou can, but the ceiling is low. Mentimeter is fine for:\n\n- A 5-question word-cloud check during an internal product review\n- A poll at a customer advisory board meeting\n- An \"are we solving the right problem?\" temperature check during a workshop\n\nIt is not built for:\n\n- Recruiting respondents outside a live session\n- 10-minute structured interviews with follow-up probing\n- Continuous discovery cadences ([see continuous discovery handbook](/docs/continuous-discovery-user-research))\n- Win/loss, churn, or PMF studies that need full transcripts\n- Thematic coding across 30+ respondents\n- Asynchronous research where the customer fits it into their day\n\nFor those, you want a [purpose-built AI interview platform](/docs/ai-moderated-interviews).\n\n## Koji as a Mentimeter complement, not a replacement\n\nMost teams that adopt Koji do not throw away Mentimeter. They use Mentimeter for live engagement (workshops, all-hands, training, conference sessions) and Koji for the actual research work that happens between those moments.\n\nIf you're an in-house researcher, that means Mentimeter keeps its job during stakeholder workshops while Koji runs your ongoing customer discovery cadence ([7-day customer discovery sprint](/docs/7-day-customer-discovery-sprint-founders)).\n\nIf you're a PM, it means Mentimeter runs your team retro polls and product council reviews while Koji runs your weekly customer interviews ([weekly customer interview cadence guide](/docs/customer-interview-cadence)).\n\nIf you're a marketer, Mentimeter runs your webinar polls while Koji runs your messaging tests and brand interviews.\n\n## Migrating a Mentimeter session or static survey into a Koji study\n\nIf you already have a Mentimeter session or a static survey, the conversion to a Koji interview is straightforward:\n\n1. Pull your existing question set\n2. Reorder into the six structured types ([choice and ranking guide](/docs/choice-ranking-questions-guide))\n3. Add dynamic follow-ups for the open-ended ones — Koji handles the probing automatically\n4. Customize the AI consultant tone (B2B, consumer, technical, casual) — see [custom AI interviewer persona](/docs/custom-ai-interviewer-persona)\n5. Publish and share the link — no scheduled session required\n\nFor a step-by-step worked example, see [how to convert a Typeform survey to an AI interview](/docs/convert-typeform-survey-to-ai-interview).\n\n## Pricing breakdown\n\n| Plan | Mentimeter | Koji |\n|---|---|---|\n| Free | 50 responses / 30 days | 10 credits |\n| Entry paid | ~$11.99/mo (Basic, annual only) | €29/mo (Insights) |\n| Mid tier | ~$24.99/mo (Pro, annual only) | €79/mo (Interviews) |\n| Enterprise | Contact sales | Contact sales |\n| Billing model | Per presenter | Per credit (1 chat / 3 voice / 5 report) |\n\nThe model itself reveals the use case: Mentimeter is priced per presenter because the presenter is the bottleneck. Koji is priced per credit because the AI moderator is unlimited — the only variable is how many respondents you want.\n\n## Other Mentimeter alternatives worth considering\n\nIf you're shopping more broadly, the most common comparisons in 2026 are:\n\n- **Mentimeter vs Slido** — both live polling; Slido is now part of Cisco/Webex\n- **Mentimeter vs Poll Everywhere** — older but solid live-polling competitor\n- **Mentimeter vs Kahoot** — gamified quizzing, classroom focus\n- **Mentimeter vs Koji** — apples to oranges (live polling vs async research)\n\nFor research-tool comparisons specifically, see our [Koji vs Typeform](/blog/koji-vs-typeform-2026) and [Koji vs SurveyMonkey](/blog/koji-vs-surveymonkey-2026) breakdowns.\n\n## Bottom line\n\nMentimeter is the best-in-class live-polling tool for presentations. It is not a research platform, and any attempt to push it into that job hits the response cap, the live-session model, or the analysis ceiling within a few studies.\n\nKoji is the best-in-class AI customer research platform. It is not a presentation tool, and never claims to be.\n\nThe decision is whether you need engagement *during* a session or insight *between* sessions. If it's engagement, Mentimeter. If it's research, Koji.\n\nMost teams need both. Few realize it until they try to run a 30-person customer discovery study inside Mentimeter, hit the limits, and start looking for a [purpose-built AI interview platform](/docs/best-ai-interview-software-2026).\n\n[Start a Koji study free →](https://www.koji.so)","category":"Comparisons","lastModified":"2026-05-31T03:16:52.311537+00:00","metaTitle":"Koji vs Mentimeter 2026: AI Customer Research vs Live Polling","metaDescription":"Mentimeter is a live polling and interactive presentation tool.
