What is Koji?
Koji's official website positions itself as an "AI-Native Customer Interviews & Research Platform": it uses research-grade agents to help you design research protocols, then has AI hosts run real conversations via voice, chat, or phone calls, delivering actionable insights for decision-making within hours. It differs from survey tools—the website repeatedly emphasizes that surveys tell you "what is happening," while Koji focuses on "why"; it is also distinct from traditional interviews, as an AI host can host hundreds of sessions simultaneously, integrating quantitative scale with qualitative depth into a single research project.
Who is it for?
- Product and user research teams conduct interviews on satisfaction and reasons for churn after product releases
- Customer success teams analyze renewal risks and identify vulnerable touchpoints for single-point-driven customers
- Global teams that need to conduct synchronized research across multiple markets and avoid translation by region
- Teams migrating from survey tools such as Typeform, Qualtrics, and Google Forms
- Researchers looking to integrate interviews into workflows such as Claude, ChatGPT, and Cursor
Key features
6AI-Hosted Real Conversations
Participants engage with the AI agent, which, according to the official website, listens, adapts, and probes each response, replying immediately after an interviewee finishes speaking with no awkward pauses.
Adaptive Follow-up Questions
Dive deeper into the "why" behind each response. The platform states that this is information that cannot be obtained through static forms, and you can set one or multiple follow-up questions.
Multiple Question Types & Multilingual Support
Single-choice, multiple-choice, rating scale, and open-ended questions are integrated into the same workflow. The official website states that it supports over 30 languages, allowing respondents to answer in their own language and accent without the need for a separate translation step.
Automatic Topic Analysis
It clusters themes, patterns, and emotions across all responses. The sample reports on the official website include the number of topics, average duration, and answer quality scores.
Quote Traceability
You can drill down into the exact original quotes behind each theme. The official website states that there is "no black box," and it supports tracing from top-level conclusion points to specific quotes.
Cross-study Querying & Delivery
You can query all past studies using natural language, with support for CSV, transcription, and report exports, as well as REST API and MCP integration.
How to use Koji
- Start with a single objective to let the research design agent generate the interview outline.
- The official website states that the research can be set up in just a few minutes, with examples keeping the number of questions under five.
- Recruitment methods include self-generated sharing links, website embedding, and a managed sample library.

- Pay attention to how credits are billed, set an answer limit, and automatically stop recruitment once the target number of responses is reached to avoid overcharging.
