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 DubTab when watching international livestreams, webinars or videos with instant translated subtitles matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

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. Check the official website for current pricing.

DubTab is a browser extension for Chrome and Edge that translates spoken audio in real time as it plays in a browser tab. Rather than requiring file uploads or exports, it listens to the audio of whatever tab is playing and produces live translated subtitles on screen, optional bilingual (original plus translation) captions, and low-latency AI voice dubbing that speaks the translation aloud. The vendor states audio stays in the tab and only text segments are processed, and that translations appear with roughly half-a-second latency suitable for live content. It supports 50+ languages and offers voice selection and volume-ducking controls. Because it works on any site with audio, supported contexts include YouTube, Twitch, Netflix, Udemy, Coursera and Bilibili, as well as meeting and conferencing tools such as Zoom, Google Meet and Microsoft Teams, where it can show what participants are saying in real time. It is aimed at online learners, livestream and international-content viewers, and remote meeting participants who need on-the-fly interpretation and captioning.
