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 Substrata when coaching sellers on social dynamics in high-stakes conversations matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

AI sales intelligence platform that analyzes the social and emotional signals behind conversations to help dealmakers read buyer intent.
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.

Substrata is an AI sales coaching and deal intelligence platform that takes a different angle from typical conversation intelligence tools: rather than focusing on transcription and summaries, it analyzes the social and emotional signals beneath sales conversations. Its core function is to model buyer psychology, attitudes, and momentum across interactions to help professional dealmakers understand intent and power dynamics. A central component is SoundWave, a real-time conversational analytics engine that listens to sales calls and analyzes voice tone, pace, pauses, interruptions, and the push-pull of social dynamics, surfacing the why behind what is being said rather than just the words. Substrata applies this signal analysis across conversations and email exchanges to gauge buyer sentiment and engagement, giving sellers and revenue leaders a read on how deals are actually progressing. The platform is aimed at B2B revenue professionals and leaders, and is positioned for smaller and mid-sized dealmaking teams that want behavioral insight into negotiations and high-value conversations. It has been recognized as a high performer across sales coaching, AI sales assistant, conversation intelligence, sales analytics, and revenue operations categories. Pricing varies by plan.
