How Hosiqo compares and tests toolsFinal recommendation
Shortlist EventCAT when providing multilingual live subtitles and audio at in-person conferences and seminars matters most, and Koji when building personas and validating early product concepts at scale matters most. Run both through a week of actual calls to see which suits your workflow.

AI-native customer research platform whose AI interviewer runs voice and text discovery conversations at scale, then synthesizes themes automatically.
EventCAT is an AI-powered real-time interpretation and subtitling platform built by XL8 Inc. for meetings, webinars, and live conferences. It converts spoken audio into live captions and synthesized voice translation across more than 50 languages, allowing multilingual audiences to follow sessions without traditional interpreter booths. The platform offers two products: an OnlineMeeting mode that integrates with Zoom, Google Meet, and Microsoft Teams, and a Conference mode designed for in-person and hybrid events. For conferences, each session generates a unique QR code so attendees can view or listen to captions in their preferred language on a phone or tablet, while subtitles can also be projected on main event screens and pushed to YouTube and OBS streams. EventCAT exposes two processing modes, one tuned for low latency and one tuned for accuracy, and supports custom glossaries for industry and company-specific terminology. After an event it produces downloadable transcripts in multiple languages and AI-generated summaries. The service advertises SOC 2 certification and a stated policy of not storing or training on user data, and it is actively operating in 2025 and 2026. Pricing varies by plan.

Koji is an AI-native customer research platform built around an AI interviewer that conducts natural, in-depth conversations with research participants at scale, removing the need to schedule and moderate live discovery calls one at a time. Teams describe what they want to learn, and an AI research agent helps define goals and generate an interview guide. The AI then runs the interviews asynchronously in either a text chat or spoken voice format, asking adaptive follow-up questions and probing for depth as a human moderator would. Each completed conversation is analyzed automatically for key moments and sentiment, and findings are synthesized across all interviews into study-wide reports surfacing themes, patterns, and recommendations, with every insight traceable back to the participant quote that supports it rather than presented as a black-box summary. Koji is used for exploratory work such as discovery, persona development, and market strategy, as well as concept and messaging testing. The product is operated from Amsterdam with EU data residency and GDPR compliance, offers a freemium entry point, and integrates with tools including Claude, ChatGPT, Cursor, and Notion via an MCP server. Pricing varies by plan. Check the official website for current pricing.
