Koji vs Pollfish: AI Research Interviews vs Consumer Survey Panel (2026)

TL;DR

Pollfish and Koji look adjacent on a category page, but they solve very different research problems.

• Pollfish is a DIY consumer survey platform with a built-in global respondent panel (Prodege-powered, 100M+ consumers across 60+ countries). You design a survey, target a demographic, pay per response (starting around $0.95), and get back quantitative data fast.
• Koji is an AI-native customer research platform. Instead of static survey forms, Koji runs AI-moderated voice and text interviews with up to three probing follow-ups per question, themes every transcript automatically, and ships a stakeholder-ready research report.

Use Pollfish when you need statistically significant consumer panel data fast — TAM sizing, brand tracking, ad concept validation against a representative sample.

Use Koji when you need why — discovery, JTBD, churn, win-loss, pricing, concept testing, value-prop validation — with depth and themed analysis that a survey panel cannot deliver.

Most serious 2026 research stacks pair both: Pollfish for breadth, Koji for depth.

What Pollfish is genuinely good at

Pollfish has earned its position as a leading DIY consumer survey platform — not a research-suite incumbent like Qualtrics, but a fast, panel-backed survey tool that fills the "I need consumer data this week" gap. Its 2026 strengths:

• The Prodege panel. Pollfish routes responses through Prodege, which operates the largest consumer panel in the US (100M+ respondents) and panels in 60+ countries. For brand-tracking, ad-concept testing, or any study where representativeness matters, that panel is genuinely valuable.
• Per-response pricing. Surveys are free to design and you only pay at checkout — public pricing starts around $0.95 per completed response. That makes ad-hoc consumer studies budget-feasible for marketing and product teams without an annual contract.
• Speed. A targeted consumer survey on Pollfish can move from draft to closed responses in a single day — faster than recruiting from scratch through a research participant marketplace.
• Quota and demographic targeting. Filter by age, gender, geography, household income, and dozens of other panel attributes for representative sampling.
• AI-assisted question wording. Recent G2 reviews call out Pollfish AI helping users phrase clearer survey questions. Useful, though it operates on the question side, not on the response analysis side.
• Easy mobile delivery. Pollfish surveys are mobile-first by design — important when most of the panel is mobile-only.

If the question is "how do US consumers aged 25-44 react to this ad concept?" and you need 500 responses by Friday, Pollfish is a credible best-in-class fit.

Where Pollfish starts to fall short

The limitations are structural — Pollfish was designed for breadth, not depth.

• No live probing. Pollfish surveys are static. If a respondent answers "because of price" on an open-ended question, that is the entire response. No AI follow-up asking which competitor, what would change their mind, or whether they have switched before. The response is a sentence, not a conversation.
• Open-ended responses are typically thin. Panel respondents are paid per completion and incentivized to finish quickly. Open text fields are commonly filled with one-sentence answers (or worse — see "good" and "none" across hundreds of responses).
• No automatic theming. You get a CSV of answers. You still have to read every open-ended response, code it manually, and write the report yourself. Or, you have to plug into a separate analysis tool.
• B2B targeting is weak. Pollfish optimizes for consumer demographics. If you need to interview "VPs of Engineering at companies with 200-500 employees who use Snowflake", the panel routing breaks down.
• No voice interviews. Pollfish is text-only. Voice modality often surfaces emotion, hesitation, and nuance that text-box survey responses flatten away — the voice vs text research data is clear on this.
• No moderator persona or research consultant. Pollfish ships a survey, not a research methodology. There is no AI consultant probing the way a senior researcher would.
• Static structure means no adaptive flow. If a respondent opens a door — "I actually canceled three months ago" — Pollfish cannot walk through it. The next question is whatever you wrote in advance.

What Koji is genuinely good at

Koji is built for depth-first research at conversation speed. Where Pollfish flattens responses, Koji deepens them.

• AI-moderated interviews. Each question can probe up to three follow-up turns. "You said price — which competitor were you comparing? What would change your mind?" Real probing, every time, on every participant.
• Six structured question types. open_ended for qualitative depth, scale for NPS/CSAT/SUS, single_choice and multiple_choice for tradeoff testing, ranking for priority elicitation, yes_no for clean binary signals. Mix-and-match in one study.
• Automatic thematic analysis. Koji codes every transcript across the study, surfaces themes with frequency counts, and pulls representative quotes. No manual tagging in Google Sheets.
• Voice + text. Voice interviews capture tone, hesitation, and emotion that text surveys cannot reach. Voice costs 3 credits, text 1 credit — both within standard plans.
• Customizable AI consultants. Define a research persona ("act like a senior B2B PM probing for budget objections") and Koji moderates in that voice across every participant.
• One-click research reports. From research question to stakeholder-ready report in hours, not weeks.
• Quality gating. Only conversations scoring 3+ on Koji quality criteria consume a credit. Low-effort responses do not bill.
• Bring your own panel — or use the API. Koji is panel-agnostic. Recruit from Pollfish or any panel provider, share a link in your CRM, or programmatically schedule via the Koji MCP server and run the study with Koji as the moderator.

Where Koji is the wrong tool

If the goal is statistically significant breadth across a representative consumer sample, Koji is not the right primary tool. Specifically:

• "I need 1,000 US consumer responses tomorrow for a brand-tracker quarterly read." — Pollfish (or another panel survey provider).
• "Run a 5-question demographic-quota survey of women 35-54 in Texas." — Pollfish.
• "Test five ad concepts at scale and rank them by recall." — Pollfish.

Koji is for the qualitative why and the structured-but-themed what next. For volume-first quantitative consumer panel work, pair Koji with a panel provider rather than asking Koji to be one.

Koji vs Pollfish: pricing breakdown for 2026

Koji pricing (2026)

• Free: 10 credits, no card required.
• Insights: €29/month (or €290/year) — 29 credits/month, AI consultant access, unlimited theming, one-click reports.
• Interviews: €79/month (or €790/year) — 79 credits/month, voice interviews, advanced analytics.
• Overage: €1/credit, flat across all plans.
• Credit cost: 1 credit per text conversation, 3 credits per voice conversation, 5 credits per report refresh.
• Quality gate: only conversations scoring 3+ consume a credit. Low-effort responses do not bill.
• Enterprise: custom.

Pollfish pricing (2026)

• Survey design: free.
• Per-response pricing: starts around $0.95/response, scales up based on demographic narrowness, panel rarity, and survey length.
• Final cost is checkout-time. You build, target, see the live price, then launch.
• Volume discounts: available on larger studies and enterprise contracts.

The pricing model is genuinely different. Pollfish is a transactional cost-per-response panel buy. Koji is a subscription with quality-gated per-conversation overage. Different shapes for different research stacks.

Worked example

For 100 themed B2B SaaS interviews with motivation probing and a stakeholder-ready report:

• Pollfish path: ~$95-$300 in panel cost (assuming you can target the demographic), + a separate transcription tool, + manual coding hours, + a separate analysis tool, + report-writing time. Realistic all-in: $1,000-$3,000 of analyst time on top of panel cost. And the responses are still single-sentence text answers without probing.
• Koji path: 100 voice conversations × 3 credits = 300 credits. On the Interviews plan that is 79 credits + 221 overage at €1/credit = €300/month. Themed analysis and one-click report included.

The Koji path is faster, deeper, and the analysis is already done.

When to use which

| Research question | Better tool | |---|---| | Brand awareness tracker across US consumers | Pollfish | | Concept-test 5 ads against a target demo | Pollfish | | Win/loss interviews with churned B2B customers | Koji | | Pricing-page validation: why did people drop? | Koji | | JTBD discovery for a new product | Koji | | Quarterly NPS-driven thematic study | Koji | | Statistically significant TAM sizing study | Pollfish | | Founder validating a concept pre-launch | Koji | | Themed value-prop testing with senior PMs | Koji | | Election-year consumer sentiment poll | Pollfish |

Pollfish alternatives — and the broader research landscape

If Pollfish is over-indexed for breadth and you actually need conversational depth, Koji is the modern alternative. For other adjacent research alternatives, see our deep-dives on Qualtrics alternatives, SurveyMonkey alternatives, Survicate alternatives, and Delighted alternatives.

For consumer-panel-specific alternatives, Suzy and Wynter are the two we get the most questions about.

Three statistics worth knowing in 2026

• 42% of startups fail because of no market need (CB Insights). Static panel surveys are weak at surfacing market need; they confirm it after you have already built. Conversational research catches it earlier — see our customer discovery guide.
• AI-native research workflows ship 10× faster. A study that took two weeks of manual work in 2022 — recruit, moderate, transcribe, code, write — ships in under a day in 2026 with Koji.
• Open-ended response depth differs by 3-5× between panel surveys and AI-moderated interviews. Average word counts for an open-ended response are typically 8-15 words on panel surveys, vs 60-200 words on AI-moderated probed interviews. The depth gap is the actual product difference.

So which should you choose?

If you need quantitative breadth across a representative consumer sample, fast and cheap — Pollfish.

If you need qualitative depth with themed analysis, structured questions, and a stakeholder-ready report — Koji.

If you can run both, pair them. Pollfish for the panel sweep, Koji for the why behind the trend.

Most product teams under $50M ARR find Koji replaces a research stack — survey tool + transcription + coding + repository + report-writing — for less than the per-response cost of running serious volume on Pollfish.
