Shortlist EventCAT when providing multilingual live subtitles and audio at in-person conferences and seminars matters most, and Sembly AI when multilingual meeting transcription matters most. Try them side by side on real calls before deciding — needs vary by team.

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. Check the official website for current pricing.
