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 Kai for Chrome when generating quick meeting summaries and action items without any setup 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.

Kai is a Chrome extension that transcribes and summarizes meetings entirely within the browser, running the full pipeline on the user's own device. Built by Morgen, the team behind the Morgen calendar app, it captures audio from any meeting or audio tab in Chrome, including Google Meet, the Zoom web client, and Microsoft Teams, without sending a bot into the call and without requiring an account or sign-up. Recording is triggered with a keyboard shortcut from the meeting tab. Audio capture happens in an offscreen document inside the extension and is transcribed locally using a Whisper speech-to-text model running via WebGPU or WebAssembly, so the audio never leaves the machine. At the end of a call, a local language model produces a clean summary with decisions, topics, and action items, including who is responsible. A side-panel interface lets users follow the transcript live during the meeting, and notes can optionally be emailed to a team in one click, at which point only the final text is shared. This makes Kai well suited to individuals who want fast, private, browser-based meeting notes without installing a desktop app or adding a visible bot, with an initial focus on English-language meetings. Pricing varies by plan. Check the official website for current pricing.
