How Hosiqo compares and tests toolsFinal recommendation
Shortlist 123 Notetaker AI when teams-centric organizations that do not have or want copilot licenses matters most, and EventCAT when adding real-time translation and captions to zoom, teams, or google meet webinars matters most. Run both through a week of actual calls to see which suits your workflow.

123 Notetaker AI is an AI meeting notes and transcription app for Microsoft Teams, built by BlueSky Apps. It runs entirely inside the Teams interface and does not depend on Microsoft Copilot, giving teams an independent option for capturing meetings. During a call, participants can open the app from the meeting window to follow AI-powered transcription that appears in real time in the Teams app sidebar. After the meeting ends, 123 Notetaker AI generates a summary and emails the meeting notes, while transcripts and notes are stored in the user's BlueSky account for later reference. Because it is installed from the Microsoft commercial marketplace and operates within Teams rather than as a browser overlay or external bot, it fits organizations that want note-taking contained in their existing Teams workflow. BlueSky Apps offers a family of conferencing add-ons across Teams, Zoom, and Google Meet, and provides a free plan with paid upgrades for additional capacity and features. The app is currently listed and operating in 2025-2026, and is documented in the company's help center and several third-party Teams tool roundups. Pricing varies by plan.

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.
