How Hosiqo compares and tests toolsFinal recommendation
Shortlist Boostlingo when adding live ai-translated captions to a webinar or virtual meeting matters most, and Koji when building personas and validating early product concepts at scale matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

AI-native customer research platform whose AI interviewer runs voice and text discovery conversations at scale, then synthesizes themes automatically.
Boostlingo is a language-access company whose product suite spans interpreter scheduling, on-site interpretation, remote video and phone interpretation, on-demand interpreter access, and AI-powered live captioning and translation. Its AI Pro engine provides transcription, live translation, and video captioning for meetings, events, and webinars, and the Boostlingo Events offering delivers continuous AI-translated captions for onsite, hybrid, and virtual sessions. Attendees can access live AI captions through a shared link or QR code without downloading anything, with captions appearing in their selected language in real time, and organizers can set default languages and enable automatic translation so the system streams translated captions throughout a session without manual switching. The platform supports a large number of languages and thousands of language pairs and integrates with major video-conferencing platforms including Zoom, Microsoft Teams, and Webex, as well as in-person and hybrid event setups. Boostlingo continues to expand its AI capabilities, including a more recent AI Interpreter that joins its AI captions and translations features. The product is actively operating in 2025/2026 and is well suited to event organizers, enterprises, and language-service providers that need scalable multilingual captioning and translation across both AI and human interpretation workflows. Pricing varies by plan. Check the official website for current pricing.

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.
