Koji — AI-powered customer research interviews
Tool Overview
Conducting customer research interviews is expensive and time-consuming. Hiring moderators, transcribing sessions, and analyzing responses can take weeks and cost thousands per study.
Koji is an AI-powered customer research platform that conducts interviews at scale, asks intelligent follow-up questions, and automatically analyzes conversations to surface actionable insights. It supports both text and voice interviews across multiple languages.
Date added June 25, 2026
Our Take on Koji
Koji automates the most time-consuming parts of customer research: conducting interviews, asking follow-up questions, and synthesizing responses into insights. For teams that would otherwise skip research entirely because of cost and complexity, that’s a meaningful unlock.
The product is early-stage with ~$15K ARR and a 3-person team based in Amsterdam. The BYOK model using Gemini keeps AI costs under your control, and the platform is GDPR and HIPAA compliant.
Voice interviews and the MCP connector are only available on Tier 2 and above, so Tier 1 buyers get text-based interviews only. There’s no mobile app, Chrome extension, or public roadmap.
At a Glance
What stands out
AI conducts customer interviews with intelligent follow-up questions, replacing the need for human moderators or researchers.
GDPR and HIPAA compliant, which matters for research involving sensitive customer or patient data.
BYOK with Gemini means no per-interview AI costs from the platform, keeping research expenses predictable.
Supports both text and AI-moderated voice interviews across multiple languages for global research projects.
Things to note
Voice interviews and MCP connector are only available on Tier 2 ($149) and above, not included in Tier 1.
Early-stage product with ~$15K ARR and a 3-person team, so the development pace may be limited.
No mobile app, Chrome extension, or public roadmap, limiting visibility into the product's future direction.
AI-moderated interviews may not capture the nuance that a skilled human researcher would catch in complex qualitative studies.

How does Koji's AI interviewing work?▼
You create a study with research questions, and Koji's AI conducts interviews with participants by asking your questions and intelligent follow-up questions based on their responses. The AI adapts the conversation in real time.
Can Koji replace traditional user research?▼
