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.

Vexa is an API-first, open-source meeting transcription and intelligence platform aimed primarily at developers and technical teams who want to build meeting features into their own products. Rather than being a polished end-user notetaking app, Vexa provides a developer toolkit: it deploys bots that join meetings via a URL, capture audio, and stream back real-time, speaker-diarized transcripts with low latency over WebSocket, alongside REST interfaces for programmatic bot control. Captured data can be stored and queried for retrieval and export, enabling teams to build live transcription, searchable meeting repositories, or downstream analysis on top of the platform. Vexa currently supports Google Meet and Microsoft Teams, with Zoom support indicated as planned, and its codebase is available on GitHub under an Apache 2.0 license, with both self-hosted and managed cloud deployment options. Because it exposes meeting capture and transcription as programmable infrastructure, Vexa is suited to engineering teams in areas like sales, recruiting, and other domains that need to embed meeting intelligence into custom workflows rather than rely on a standalone consumer app. It is best for developers who want control over how transcripts are captured, stored, and used. Pricing varies by plan. Check the official website for current pricing.
